Wear secure water shoes
Stony, slippery surfaces and short swims make closed, grippy water shoes essential for traction and foot protection.
Leave sunscreen and lotions behind
Oils and chemicals harm cave ecosystems and are not permitted; use provided wetsuits and rely on indoor protection instead.
Bring a swimsuit and quick‑dry clothes
You’ll get wet walking and swimming for about 1–1.5 hours inside the cave; a change of clothes is helpful for the buffet afterwards.
Be honest about medical limits
The tour requires moderate to high fitness and involves uneven terrain and swimming — disclose spinal, heart or pregnancy concerns in advance.
Closed‑toe water shoes
Provide grip on wet rock and protect feet during walks and swims.
Swimsuit
Worn under the provided wetsuit for comfort during submerged sections.
Lightweight change of clothes and towel
Dry clothes and a towel are useful after the cave and before the buffet.
Small waterproof bag or case
Protects phone or small valuables during transfers and wet sections (large electronics are best left in lockers).
