Great experience!

The staff is awesome! So helpful and funny. Nice to be able to swim into the cave on our own, compared to other groups that were roped together like little kids.

Great adventure and crew!

Well organized and efficient crew to help with all needs. Plenty of water available and lunch was good and plentiful with both a bit spicy and not spicy with fruit and cola beverages. Kept us on schedule with a nice bit of time at each stop. Snorkeling was good with Emerald cave adventure something special. Would highly recommend if you can.
