We booked this trip because of the marine biology and conservation efforts. I am so glad we did. Heather was wonderful, she taught us about the local ecosystem without making it feel like a lecture. Wade was awesome as well, very funny and very knowledgeable about the area. He made it his mission to find us some dolphins to see. They provide all snorkel equipment, including a wet suit in colder months, which I was grateful for. They also have float belts for those who are not strong swimmers. The snorkel location was about 9-15 feet I believe. Heather snorkeled with us and guided us and taught us along the way. She found a purple sea urchin to show us who had camouflaged with shells! After the snorkel she cut up fresh fruit for us, which was delicious. There is a “head” on the boat (or bathroom) which is very much like an airplane bathroom, except for the flushing which you do by hand. There is plenty of seating down below with shade, and an upper deck to watch from. We saw dolphins, a manatee, and a sea turtle!
