We were traveling with 6 yo kid, and I want to say special thanks to our boat nr 18 crew for helping to encourage him and for support :) all was good, really recommend. Guys from boat 18 - special huge thanks again, you qre great! :)
Wonderful experience with plenty of time to see enough aquatic life. Check with the tour operator about the water conditions and sea lice (Thimble jellfish) so you can pack the appropriate clothes. we were stung by lots of sea lice at the first snorkeling pot. The current had brought them in (2 Feb 2025). It was a bit uncomfortable but woryh the discomfort. long sleeve swim shirt and should resolve the issue.
