"If you are deciding on doing this tour, just do it! Experience this breathtaking environment by kayak so you can beach the boat and get out on the beach, unlike the motor boats that can't stop in the cave. Be sure to find the exact meeting point at this marina. We had our vouchers and were given really bad information twice as where to find the boat. The marina in huge so we went to a different dock and missed our tour. The operators were excellent though. We explained our situation and since the next morning want sold out, they let us come on no extra charge. Thank you for that!
Please get there early and find the correct spot as there is no signage anywhere."
