Select participants and date
You step off the van in Sabang and the air changes—thick with wet limestone and the salt of a nearby sea. Local boats wait on a narrow river that threads through mangroves, and your guide points to a cave mouth where darkness seems to inhale itself. The boat slips forward; stalactites hang like the teeth of some slow-moving beast, and the river, almost black, carries the sound of voices and drip after drip into the cavern’s hush.

Adventure Tips
Book early and check pickup
Shared tours fill quickly—confirm your hotel pickup point and be ready 30 minutes before departure to avoid delays.
Bring a waterproof layer
Boat rides and sudden tropical showers make a lightweight rain jacket or a pack cover useful year-round.
Non-slip footwear only
Docks and trail sections can be wet and uneven—sturdy water shoes or trail sneakers reduce slip risk.
Pack reusable water
Tap water isn’t always available during transit—bring a refillable bottle and use provided refilling stations when possible.
