Was hoping to see dolphins 🐬 and we got to see a few!! Also the islands were amazing the beach was all shells 🐚 šŸ˜ so we got to collect a few for keepsakes. Our guide was very informative šŸ‘Œ and learning about the structures in water and the animals made it a great experience. Would definitely recommend and also go again if I ever come back!
Amazing day!

Wesley and Sonia were extremely pleasant and knowledgeable. Got to see dolphins and many different birds. The dolphins came pretty close to the boat. Got off the boat to do some shelling for a while. Visited the dome houses. Would highly recommend.
Beyond our expectations!

You can see views of South Marco that you cannot see by land. Fun time with family. Saw lots of dolphins and enjoyed Captain Dave’s stories. Would highly recommend coming by.
We had a wonderful morning with Captain Joe of Eco Endeavors!

He was so personable and allowed our family to decide exactly what we wanted to do for the whole trip. We were able to see the dome homes, stop for some great shelling, and watch lots of dolphins! We can't wait to do this again!
