Went on a mid-morning snorkel tour of the Grecian Rocks! Literally couldn’t improve that experience if we tried. Adam and Annie kept us informed, safe, and kept us having a great time. Oh, and the coral reef was incredible! We rented our flippers, snorkel, mask, and they give you an air valved snorkel vest which was essential for this poor swimmer. Unbelievable, best part of our whole vacation… and it was a great vacation. Thanks!

A beautiful place to paddleboard or swim. they have kayak rentals if you don't have your own kayak or paddleboard. i watched the sun set over the mangroves, and it was just stunning (and private!) you can either walk or drive to the short mangrove boardwalk. clear water and beautiful plants. i loved this place.

The visitor center and aquarium is underwhelming. The boardwalk loop is a great way to walk through the mangroves. The glass bottom boat tour was a neat experience, worth the cost. However, if the boat would have been full I think the enjoyment would have been reduced.

Beautiful park with a great food truck for some great food and refreshments. (Blue Heron) Beautiful views. The mangrove is awesome to see up close. Mango, avocado, and lime trees at the end of one of the trails. Rentals of kayaks available and boat tours. Saw beautiful fish, stingrays. Highly recommend this park.

We did a 9:00am snorkeling tour through the park. They took us to grecian rocks. Adam was our captain. I cannot forvthe life of me remember his crews name. They were both amazing. The snorkeling experience was amazing as we were all newbies. I took my husband and two children. We were in about 10 feet of water. We saw a ton of amazing colorful fish. We saw lots of coral, queen conch shells, and two different species of sting rays. Top 10 experience of my life. 10 out of 10 recommend to anyone who has never been snorkeling! The aquarium afterwards was awesome as well.
