This was such a great tour. The tour guides were so friendly and knowledgeable about the wildlife. I'm a local and plan to do this tour often. It was such a fun day. Shell key was so beautiful as well.

So fun and relaxing! We all didn't want to leave... The water was crystal clear, shells everywhere and it was totally uncrowded. Had the best time. Could have stayed all day!

Booking was easy, details were clear and the captains were great! We had the best time finding dolphins, and riding the boat- then found so many shells! The crew helped us explore the water to find crabs, conchs and more- so cool- then the dolphins joined us for a swim. Great experience especially for the cost!

We had the best time on this water tour! We have 3 young kids - 7, 4, and almost 2 and they all had a blast. The Captain made sure to seek out the dolphins and make sure we all got plenty of chances to see them -even taking extra time. We got to get off and explore the sea shells at the island and when some other people aboard the boat got cool sea shells that the captain realized were still alive he was willing to give her a similar seashell of his own so she could still go home with one. The staff were very knowledgeable. The captain let our kiddos "drive" the boat on the way back. It was truly a great all around experience and we would definitely do it again.

Captain John and first mate Jennifer were great and entertaining. We saw lots of dolphins, and had a great time shelling. We would do this trip again without a doubt.

To start, I had purchased the 2.5 hour tour that went to Shell Key. Due to weather issues I got a call saying our tour was being canceled so they offered us the 4 hour tour that was a day earlier. I am so happy we were able to make that work. It was SO much fun.
The 2 gentlemen that were our guides were awesome! Very informative and super friendly.
I would definitely recommend this experience.

Come prepared to walk the beach with water shoes- the shells are sharp on tender feet. Bring a shell bag.

It was a super fun and easy excursion. Our captain John and Jennifer were great. Beautiful sites and the shelling was so relaxing! Got to see a lot of dolphins jumping all over
Gail_G, Mar 2026
What a wonderful adventure! The crew was so nice & informative. Made several stops to watch the dolphins play! Shelling was also wonderful! Great experience! Will definitely do another trip with island adventures! Highly recommend!!

We actually transferred to the Dolphin chase , snorkeling & island adventure.
The operating family; Betty, Mike and captain John welcomed us aboard like we were visiting their home for dinner.
We were made to feel comfortable and safe.
Catered to all twelve passengers individual requests.
If you go please ask Captain John to do his best to introduce you to "Steven" the cheeto stealing bird.

Amazing experience today! We had so much fun and learned a lot! The guides were so nice and gave background information on the shells and guidance on where we should look. Must do with kids!

Relaxing. Professional with casual feel. Lots of shelling. Island is just nice to go to. Boat is great. Captain and first mate are friendly and knowledgable. Would highly recommend.
Vanessa_S, Feb 2026
My friend and I had a great time! We didn't find any big shells that didn't have live animals in them, but we found some smaller shells. Saw plenty of playful dolphins and enjoyed the boat ride to the island.
Annie_K, Feb 2026
We had booked a much more expensive tour that cancelled last minute. I booked the ferry and would not have changed a thing Sierra was awesome! Very quick boat ride, shells everywhere.

Betty and John were great guides with lots of knowledge about the area, plus the dolphins, birds, fish and seashells. They even recommended a great restaurant called O'Maddy's.
Searching for seashells was really cool. Found some great treasures. If it is cold out, make sure to bundle up! That wind on the water is cold!
Thank you again for a great adventure.Weatherade Challenge

Our captain was welcoming and knowledgeable about the sea life and the history of the local area. He fielded all questions and answered to his best knowledge. When we got to Shell Island , he didn’t just leave us. He walked along with whom ever had questions and showed us how to handle sea life we encountered. He searched for shells to give to passengers to make sure everyone had a good experience. It was a peaceful boat ride with marine life and beautiful views! Would definitely recommend .

Captain Mike was great. When my mom was getting overheated, he took great care of her. We had a wonderful time. Will definitely do it again!

I ended up doing Egmont Key Island instead and was glad I did. It was a 4 hour trip and I had so much fun shelling, hiking, and snorkeling.
Bridget_S, Aug 2025
Best part of our trip! Go early as possible it’s a great way to start a vacation day, by far my favorite thing I’ve done in Florida. We have so many cool shells to make our own crafts to remember the trip! We saw dolphins and manatees, the captain is very nice he helps to find cool shells and gave us snorkels to use. Very chill and knowledgeable great time 10/10 definitely doing this everytime we come back!

Captain Tom was amazing…. funny and knowledgeable….. we were able to stop at a very tiny island where sand dollars were plentiful on our way back to the marina….we booked another boat excursion for the following Saturday…. To another island…. there is a cooler on board where you can bring your own drinks of any kind and keep them in the cooler….
