Explore Samar's Langun-Gobingob cave system, a massive network in a 2,968-hectare karst area. Guided tours are mandatory. Choose from several entrances, each with unique challenges: rappelling 60 feet or navigating submerged tunnels. Expect giant formations, underground rivers, and varying difficulty levels. Essential: proper safety gear and training. These caves are awe-inspiring.
Reaching Langun-Gobingob Cave
Langun-Gobingob Cave, Samar Island Natural Park (Calbiga, Samar), is located two hours from Leyte (via Calbayog or Tacloban airports) or a road trip from Manila to Matnog, Sorsogon, then ferry to Allen, Samar.
From Allen, it's a two-hour drive to Calbiga.
Register at the Calbiga tourism office and pay fees.
Bring a helmet, headlamp, and rappelling harness.
Guided tours only.
Expect a one-hour trek to the cave entrance.
The final approach—a one-hour trek over grass, stones, and mud—is best done by motorcycle to the jump-off point, followed by a twenty-minute motorcycle ride and a forest hike.
Prepare for challenging terrain and rain.
Cave System's Immense Scale
Samar's Langun-Gobingob Cave system, within a 2,968-hectare karst area, is immense.
Gobingob Chamber holds multiple football fields. Langun Cave measures 270 meters long and 160 meters wide. These aren't cavities; they're subterranean cathedrals, too large for complete illumination.
Giant columns, stalactites, and stalagmites, some chandelier-like, fill the caves. Intricate flowstone formations, such as Langun-Gobingob's "The Stage," are breathtaking.
Underground rivers and pools add complexity. Langun Cave's waterfalls, rivers, and islets support rare life: blind crabs and seven-centimeter hypogean blind fish.

Samar's cave entrances demand skill and preparedness. Access varies.
Linao Cave: Rappel or submerged tunnel. Dark, wet; high water. Stalactites, stalagmites. Guided tours; waterproof gear needed.

Planning Your Trip
Plan your Samar spelunking trip carefully.
Choose a base in Eastern Samar or Samar (Guiuan, Calbiga, or Catbalogan).
Select your cave (Linao, Central, Langun-Gobingob, or others). Contact a local guide; Jayson of Yes Org guides Linao Cave (P150/person).
Factor in gear costs and accommodation (local towns or ecolodges like Calbiga-Sinpe).
Reach your base via flights, buses, or private vehicles; use multicabs or tricycles to caves. Allow 30 minutes travel time from Guiuan to Sulangan.
Spelunking is strenuous; be fit.
