More ways to explore the area's outdoor wonders
You climb into a longtail as limestone cliffs narrow and the sea changes color—green glass giving way to teal—until the boat slips under a low rock arch and into a dark throat. Light squeezes through at the far end; the cave exhales a bright, tropical hush and a hidden crescent of sand appears like a secret kept by the island.

History
The cave and surrounding karst islands are the product of millions of years of carbonate rock erosion and coral accretion; local fishermen and island communities historically used these coves for shelter and small-scale fishing.
Conservation
Coral reefs here are fragile—support operators who use mooring buoys, avoid anchoring on coral, and encourage reef‑safe sunscreen and no‑touch policies.

Check tide times
The cave’s passage is accessible only at certain tides—confirm with your guide and follow their timing to enter safely.
Bring a snorkel mask
Masks fit better when personal—many tours supply basic equipment but a good personal mask keeps water out during reef swims.
Use reef‑safe sunscreen
Coral reefs are sensitive—choose mineral sunscreen and reapply before entering the water to protect marine life.
Waterproof your valuables
Short swims and wet landings are standard; use a dry bag or waterproof phone case for cameras and documents.
Swimwear and quick‑dry clothes
Comfortable swimwear and a lightweight cover-up for boat travel and beach time.
Snorkel mask (personal)
A well-fitting mask improves comfort and lets you focus on reef life during stops.
Reef‑safe sunscreen
Protects your skin and the coral—choose mineral-based SPF and apply before entering water.
