Amazing tour of the 10,000 islands
We did the sunset tour and our entire family loved it. We saw dolphins, a shark, crabs, and other wildlife. The tour captain was fun and entertaining. I highly recommend it.
Was a great way to spend the morning!
Was hoping to see dolphins and we got to see a few!! Also the islands were amazing — the beach was all shells so we got to collect a few for keepsakes. Our guide was very informative. Would definitely recommend!
Amazing day!
Wesley our captain was wonderful and full of information. We saw many dolphins, heron, egrets and even manatee. The remote island was a super treat and the shelling was outstanding.
Great experience!
Wesley and Sonia were extremely pleasant and knowledgeable. Got to see dolphins and many different birds. The dolphins came pretty close to the boat. Visited the dome houses. Would highly recommend.
Beyond our expectations!
Amazing, me and my friend booked it last minute, and it was beyond our expectations! The Captain and our tour guide, Campbell, was very professional, friendly, and super fun! We got to see plenty of Dolphins!
The boat tour was excellent!
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.
Wonderful morning with Captain Joe!
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!
