Samar, the Philippines’ third-largest island, splits into three provinces—Northern, Eastern, and Western Samar—offering diving far removed from mainstream tourist circuits. Biri Island in Northern Samar provides drift diving through the San Bernardino Strait, while Guiuan in Eastern Samar hosts the 52-hectare Pearl Island Marine Sanctuary. Divers reach Samar by flying to Tacloban (1.5 hours from Manila) then traveling overland, or by direct flights to Catarman for Northern Samar access. This destination suits adventurous divers comfortable with limited infrastructure and strong currents.
Samar sits at the eastern edge of the Visayas, bordered by the Philippine Sea to the east and the Samar Sea to the west. The island’s three provinces each offer distinct diving experiences: Northern Samar centers on Biri Island where the San Bernardino Strait funnels water between the Samar Sea and Philippine Sea, creating drift diving conditions comparable to Tubbataha; Eastern Samar around Guiuan features calmer sanctuaries recovering from Typhoon Yolanda’s 2013 devastation; Western Samar offers access points but limited diving infrastructure. The region falls within the Coral Triangle and the Samar Sea Protected Seascape, hosting over 300 documented coral species.
Unlike developed destinations, Samar lacks the tourist infrastructure divers expect—a single dive operator serves Biri Island, and Eastern Samar diving requires arranging independent dive masters. This appeals to divers seeking unexplored waters without crowds but demands flexibility and advance planning. Samar suits experienced divers with Advanced Open Water certification or higher, particularly those comfortable with drift diving and current management. Beginners can dive calmer sites around Guiuan but should expect basic facilities and limited equipment availability.
Samar offers what few Philippine destinations still can: genuinely uncrowded diving with minimal tourism infrastructure and strong marine biodiversity within the Coral Triangle.
Dive sites concentrate around two areas: Biri Island in Northern Samar (accessed from Lavezares) and Guiuan in Eastern Samar. Boat rides range from 10 minutes to over an hour depending on destination.
| Site Name | Depth | Difficulty | Best For | Key Species |
| Garon Wall | 10-27m+ | Advanced | Drift diving | Trevally, jacks, reef sharks |
| Managtuka Sanctuary | 5-18m | Intermediate | Reef exploration | Giant clams, nudibranchs, juvenile fish |
| Cogon | 8-20m | Intermediate | Macro photography | Nudibranchs, anemonefish, sea weeds |
| Pearl Island | 5-15m | All Levels | Sanctuary diving | Lobsters, hard corals, giant clams |
| Salvacion | 10-22m | Intermediate | Wall diving | Soft corals, reef fish, sea snakes |
The signature drift dive of Biri Island drops along a dramatic wall with San Bernardino Strait currents carrying divers past schools of trevally and occasional reef sharks. Visibility varies from 8-20 meters depending on tidal conditions. The wall features healthy soft coral growth and crevices harboring lobsters and groupers. Only diveable during specific tidal windows—experienced guides time entries to match current direction. Advanced Open Water certification required; strong negative entry skills essential.
A protected area just offshore from Biri town featuring gentle slopes covered in hard coral formations. Giant clams (Tridacna gigas) appear at multiple depths, with strict penalties for touching. The sanctuary hosts exceptional nudibranch diversity—three species spotted in a single dive is common. Calm conditions most mornings before afternoon winds build. Schools of dalagang bukid (fusiliers) feed in the shallows.
Eastern Samar’s primary dive destination sits 30 minutes by boat from Guiuan. The 52-hectare sanctuary surrounds a former Bureau of Fisheries pearl farm established in 1972. Shore entry leads to slopes with recovering hard and soft corals—debris from Typhoon Yolanda still visible in some areas but marine life returning strongly. Lobsters shelter in crevices, and giant clams dot the seafloor. Visibility reaches 10-15 meters in calm conditions.
A Pacific-facing site on Biri Island’s eastern shore, diveable only during summer months (March-May) when habagat winds subside. The terrain resembles green underwater hills covered in sea weeds with hard corals interspersed. Strong nudibranch populations and sea anemones hosting multiple clownfish species. Current increases in afternoon—morning dives recommended.
Samar’s waters fall within the Coral Triangle, benefiting from the biodiversity hotspot status this designation confers. The Samar Sea alone contains over 300 documented coral species across its 3,870 square kilometers, with reef systems extending throughout the northern and eastern coasts.
Macro subjects dominate Samar diving. Nudibranchs appear in unusual density, particularly around Managtuka and Cogon where three or more species on a single dive is typical rather than exceptional. G
iant clams maintain healthy populations in protected sanctuaries—Tridacna gigas specimens exceed one meter in some locations. Pelagic encounters increase around Garon Wall and San Bernardino Strait sites where currents concentrate fish activity.
Trevally schools, Spanish mackerel, and yellowfin tuna pass through seasonally. Reef sharks patrol deeper sections. Sea snakes appear regularly but maintain typical evasive behavior. Reef fish populations reflect limited fishing pressure in remote areas. Groupers, snappers, sweetlips, and angelfish occupy typical depth ranges. The recovering Pearl Island sanctuary shows increasing fish density as protection continues post-typhoon.
Samar’s eastern exposure to the Philippine Sea creates distinct wet and dry seasons affecting dive conditions significantly.
Peak Season (February-May): Dry season brings the best visibility (15-25 meters), calmest seas, and accessible Pacific-facing sites. March through May offers optimal conditions for San Bernardino Strait drift diving when currents become predictable. Water temperatures reach 28-30°C.
Shoulder Season (November-January): Transitional weather with increasing visibility as amihan (northeast monsoon) establishes. Some sites accessible but Pacific-facing locations rough. Water temperatures 26-28°C.
Off-Season (June-October): Southwest monsoon (habagat) brings rain and rough seas, particularly affecting Biri Island’s Pacific sites. Guiuan diving remains possible during calmer periods. Visibility drops to 5-12 meters. Typhoon risk peaks August-October.
Water Temperature: Ranges from 26°C during cooler months (December-February) to 30°C in summer (April-May). A 3mm wetsuit suffices year-round; cold-sensitive divers may prefer 5mm November through February.
Visibility: Highly variable based on season, tides, and recent weather. Expect 5-12 meters during wet season, 15-25 meters during dry season peaks. Drift sites in San Bernardino Strait can experience reduced visibility during strong current periods.
Currents: The defining characteristic of Samar diving. San Bernardino Strait currents reach 2-4.5 meters per second—faster than most recreational divers can swim against. Even “calm” sites may experience 1-2 knot currents. All diving requires current awareness and ability to execute negative entries.
Recommended Gear: Surface marker buoy (SMB) mandatory for all drift diving. Audible signaling device. Dive computer with current dive log. Reef hook for specific sites. Backup mask and torch for variable visibility conditions.
Safety & Emergency: No hyperbaric chamber exists in Eastern Visayas. Nearest chambers: Manila, Cebu, and Subic Bay. Emergency evacuation to Manila takes 3-4 hours minimum. Dive conservatively—surface early if any symptoms develop.
Accommodation options remain limited across Samar, concentrated in Catbalogan (Western Samar), Biri Island, and Guiuan.
Premium: No high-end resorts currently operate in Samar’s diving areas. Divers seeking luxury should base in Tacloban (2-3 hours away) for accommodation, though this adds significant travel time to dive sites.
Browse dive resorts and accommodations across Philippine dive destinations for alternatives. Compare regional rates through Agoda for current availability.
Samar’s diving infrastructure remains severely limited compared to developed destinations. Equipment rental available but limited inventory—bringing personal gear strongly recommended. The center arranges boat diving to all 20+ mapped sites around Biri and the San Bernardino Strait.
Eastern Samar lacks established commercial dive operators. Diving around Guiuan and Pearl Island requires arranging independent dive masters locally—inquire through Guiuan tourism office or accommodation owners. Bring all equipment; rental not reliably available.
Explore scuba diving schools and centers throughout the Philippines for additional training options before visiting Samar.
No liveaboard operators currently service Samar waters. The region’s remote location, limited diving infrastructure, and challenging currents have not attracted commercial liveaboard routes. Divers seeking multi-day boat trips should consider nearby Leyte, which occasionally appears on liveaboard itineraries exploring the Visayas.
Browse schedules on Liveaboard.com or Divebooker for vessels operating in Eastern Visayas waters that may include Samar stops on extended charters. Check liveaboard operators serving Philippine waters for alternative routes.
Samar’s remote location means freediving infrastructure remains undeveloped. The province offers adventurous conditions for experienced, self-sufficient freedivers—strong currents, variable visibility, and limited emergency support require careful planning. No dedicated freediving schools currently operate in the region. Visiting freedivers should bring their own safety equipment and ideally travel with a buddy experienced in remote diving. Local boatmen can provide surface support but lack freediving-specific training.
The uncrowded waters and unexplored reefs appeal to adventurous freedivers comfortable with frontier conditions. Explore freediving schools and centers in the directory.
No dedicated dive gear retail shops operate in Samar. The nearest equipment purchases available in Tacloban offer limited selection focused on snorkeling gear rather than scuba equipment. Emergency equipment replacement requires travel to Cebu or Manila. Explore dive gear shops in major Philippine cities to arrange equipment before traveling to Samar.
Samar’s marine areas benefit from several protected zones though enforcement varies by location.
Biri Island Environmental Fee: PHP 50 (~USD $1) collected upon arrival in Lavezares. Funds support local conservation monitoring.
Managtuka Sanctuary: Established marine protected area with active local management. Giant clam touching or removal carries penalties up to PHP 150,000 (~USD $2,500). Night diving requires operator coordination with barangay officials.
Pearl Island Marine Sanctuary: The 52-hectare protected zone around Kantican Island prohibits fishing and extractive activities. Separate sanctuary fees may apply—confirm with local guides. The Bureau of Fisheries maintains oversight though facilities were damaged in 2013 and recovery continues.
Samar Sea Protected Seascape encompasses waters west of the island, extending protections across critical ecosystems. Spearfishing prohibited in designated sanctuary zones. Support ocean conservation organizations working to protect Philippine marine ecosystems.
Samar offers significant land-based attractions that complement diving exploration.
Biri Rock Formations: Seven massive limestone boulders—Magasang, Magsapad, Makadlao, Puhunan, Bel-at, Caranas, and Lugsukan—shaped by Pacific waves and San Bernardino Strait currents. Boat tours PHP 1,000-1,500 (~USD $17-25) for groups. Habal-habal tours PHP 300-500 (~USD $5-8) full day.
Sohoton Natural Bridge National Park: Cave systems, underground rivers, and natural rock bridges accessible from Basey, Western Samar. Full-day tours PHP 1,500-2,500 (~USD $25-42) including transport and entrance fees.
Homonhon Island: Historical significance as Ferdinand Magellan’s 1521 Philippine landfall. Accessible from Guiuan by boat (2 hours). Kayaking, surfing, and beach exploration available.
Calicoan Island: Surf breaks on the Pacific-facing coast near Guiuan. Board rentals and lessons available seasonally. Book activities through Klook for organized tours when available, or arrange locally through accommodation providers.
Community Vibe: Samar remains largely untouched by diving tourism. Expect curiosity from locals unaccustomed to foreign visitors and genuine hospitality uncorrupted by tourist industry dynamics. English proficiency varies—basic Waray or Tagalog phrases appreciated. The diving community effectively consists of Biri Resort’s small operation and occasional visiting divers.
General Customs: Waray-Waray people value respectful interaction and modesty. Remove shoes when entering homes. Ask permission before photographing people, especially in smaller communities. Catholic religious observances influence daily life and business hours.
Tipping Culture: Tipping is entirely optional throughout the Philippines and not culturally expected. If dive guides provide exceptional service, PHP 200-500 (~USD $3-8) per day is generous but never required. Do not feel obligated to match Western tipping percentages.
Safety & Scam Awareness: Samar presents minimal tourist-targeted scam risk due to low visitor numbers. Primary concerns involve logistics rather than crime: verify boat and vehicle arrangements before departing, carry cash (ATMs unreliable outside Catbalogan and Tacloban), and confirm accommodation bookings directly. Petty theft remains rare but secure valuables as anywhere. Typhoon season (August-October) demands weather awareness and flexibility.
To Northern Samar (Biri Island): Philippine Airlines operates Catarman flights from Manila twice weekly (1 hour 20 minutes). Fares range PHP 2,100-10,200 (~USD $35-170) depending on booking timing. From Catarman Airport, hire tricycle to town center, then jeepney to Lavezares (1 hour, PHP 80/~USD $1), followed by boat to Biri Island (1 hour, PHP 50/~USD $1 public boat or PHP 1,000-1,500/~USD $17-25 private charter).
To Eastern Samar (Guiuan): Fly to Tacloban (multiple daily flights from Manila, 1.5 hours, PHP 2,500-8,000/~USD $42-133), then air-conditioned van to Guiuan (3-4 hours, PHP 270-500/~USD $5-8). Vans depart Tacloban terminal hourly.
From Tacloban to Western Samar: Air-conditioned vans to Catbalogan depart frequently (2-2.5 hours, PHP 150-200/~USD $3). San Juanico Bridge connects Leyte to Samar.
From Sorsogon (Luzon) to Northern Samar: RORO ferry from Matnog to Allen (2 hours, PHP 200-350/~USD $3-6 passenger, PHP 1,500-2,500/~USD $25-42 vehicle). From Allen, transport continues to Catarman or Lavezares. Book transport via Bookaway or compare routes on 12Go for ferry and bus connections.
Tricycles serve short distances within towns (PHP 20-50/~USD $0.50-1). Jeepneys connect municipalities along main roads. Habal-habal (motorcycle taxis) reach remote areas—negotiate fares before riding. Boat charters for island hopping run PHP 1,000-1,800 (~USD $17-30) depending on distance and group size.
Booking Timeline: Contact Biri Resort & Dive Center minimum 2-4 weeks before arrival to confirm availability and equipment status. Peak season (March-May) requires earlier booking. Flights to Catarman sell out quickly—reserve 4-6 weeks ahead. Eastern Samar diving requires advance coordination with local dive masters through tourism offices.
Dive Insurance: Essential given Samar’s remote location and evacuation distances. The nearest hyperbaric chambers in Manila and Cebu require 3-4+ hours to reach. Secure coverage through DAN, Diveassure, or SafetyWing before arrival. Policies should explicitly cover drift diving and emergency evacuation.
What to Pack: Complete dive gear (rental unreliable), SMB and reel, backup torch, reef hook for current-heavy sites, 3-5mm wetsuit, save-a-dive kit, personal medications (pharmacy access limited), cash in PHP (ATMs unreliable), waterproof bags, mosquito repellent, and rain gear year-round.
Samar challenges beginners due to strong currents, limited infrastructure, and remote conditions. Pearl Island sanctuary near Guiuan offers calmer diving appropriate for Open Water certified divers, though equipment availability remains problematic. Most Biri Island sites require Advanced Open Water certification and drift diving experience. New divers should gain experience at developed destinations like Anilao or Moalboal before attempting Samar. If visiting as a beginner, dive conservatively and clearly communicate comfort levels with guides.
March through May offers optimal conditions with calm seas, 15-25 meter visibility, and accessible Pacific-facing sites. February provides good diving as dry season establishes. June through October brings southwest monsoon with rough seas, reduced visibility, and typhoon risk—avoid this period for dedicated dive trips. November through January works for protected sites but Pacific-facing locations remain rough.
Expect PHP 1,500-2,000 (~USD $25-33) per guided dive through Biri Resort & Dive Center. Two-tank boat dives run PHP 2,500-3,000 (~USD $42-50). Budget accommodation starts at PHP 200 (~USD $3) for homestays, with mid-range options at PHP 1,500-2,500 (~USD $25-42) nightly. Transport from Manila adds PHP 3,000-12,000 (~USD $50-200) depending on route and timing. Total budget for a 4-day trip: PHP 15,000-25,000 (~USD $250-417) excluding international flights.
Samar delivers strong macro subjects—nudibranch diversity around Biri rivals more famous destinations, with multiple species appearing on single dives. Giant clams maintain healthy populations in sanctuaries. Drift diving sites produce trevally schools, mackerel, and occasional reef sharks. Reef fish remain abundant due to limited fishing pressure. Sea snakes appear regularly. Don’t expect whale sharks or mantas—Samar’s appeal lies in healthy reef ecosystems and macro rather than megafauna.
Samar presents minimal safety concerns for divers. The region sees little tourism, eliminating common scam risks. Primary challenges involve logistics rather than security: unreliable transport schedules, limited ATM access, and basic facilities. Carry sufficient cash, confirm bookings directly, and maintain weather awareness during typhoon season. The diving itself demands respect—strong currents and remote locations mean conservative dive planning is essential. Bring dive insurance that covers emergency evacuation given chamber distances.
