Great tour. The captains were great, friendly, knowledgeable, considerate and fun. We saw lots of dolphins and lots of shells! Definitely recommend this tour with John and Jennifer!

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.

Thanks!

Great day with some great people!

Cheyenne_L, Jul 2026
The whole experience was beyond amazing!! We originally booked a 9am tour, but due to 2 crashes and a couple gridlocks, our 45 minute drive turned into an hour and 45 minutes... The staff of Calypso Cat didn't hesitate offering to get us booked on another tour that afternoon that turned out to be an upgrade without having us pay the difference! Very generous of them! They were super friendly and informative throughout the tour. We saw many dolphins, found some neat shells at Egmont key, went snorkeling and saw some cool fish, and genuinely had a great time with them. They also offered complimentary water, had life jackets the kids could use, as well as pool noodles to float with. Definitely plan on booking another tour with them next time we're in Florida!

Response from Host, Jul 2026

YAY! We're so glad you were able to make it our with us! We understand that things can happen and we always try our best to work things out. See you again soon!

A Perfect Way To See Shell Key

Dena_J, Jun 2026
Amazing! We saw manatee and dolphins. Shell Key was beautiful. John and Jen were so good about pointing things out and stopping for us to view the wildlife. The excursion was well planned and we had plenty of time.

Response from Host, Jul 2026

We absolutely love the wildlife and we enjoy viewing thew just as much as our guests. Thanks for the awesome review!

John and Jen were great tour operators. We spent enough time on the island to acquire shells and enjoy the scenery. We had a great time!

Morning cruise

Deborah_F, Jun 2026
The morning ride is perfect if you want the rest of the day to relax. Love the dolphins! Need to scuba to find nice shells

Response from Host, Jul 2026

Yes, Although many beautiful shells do wash up on shore each day ,snorkeling can provide great shells too. Thanks for the great review!

Amazing Experience

Best in the Bay

Jen_K, Jun 2026
Hands down the best in the area for any outing. Forget about the bigger companies this family run business was is still the best in the bay. Very friendly, knowledgeable, and caring staff. Will definitely do again if we’re back in the area.

Response from Host, Jul 2026

Thank you so much! We're very proud of what we do and your compliments mean a lot to us!!!

Nice morning on the water

Rachael_S, Jun 2026
This was a nice boat ride with very friendly folks on board (those running the boat, and the other passengers too) we saw lots of dolphins and our Captain was respectful of them as to keeping a safe distance and not chasing them around (a major plus for this tour!) - minus one star because the shell area was average in my opinion and nothing special in the finding shells category-- Our Captain again tho went in the water and found several sand dollars and shells for folks on the boat, which was really nice of him.... They provide snorkel equipment, bags for shells and ice cold water. This was a nice way to spend the morning!

Response from Host, Jul 2026

Thanks for the great review!

Worth it!

Stephanie_H, Jun 2026
Beautiful day! We found some interesting shells. The captain even hunted for rare shells for us in deep water.

Response from Host, Jul 2026

Thanks for your 5 star review!

A Fever of Stingrays highlight of the trip!

Michelle_N, May 2026
Guides were great and it was nice to see the dolphins and stingrays. But the shell experience was disappointing. No large shells like were advertised.

Response from Host, Jul 2026

We remember you well Michelle! The gentleman sitting next you you that day did find a huge shell (his review is just before yours in the list). Shelling is such a fun treasure hunt and finding that special one is what makes it super exciting, maybe you'll be be the one to find it next time! We thank you for your review and wish you many exciting adventures in the future!

Recommend!!!

Alexus_L, May 2026
10/10 experience. The boat was really spacious, clean and accessible to get on and off. I loved getting to get off the boat to go shelling. I found a massive sea shell! The tour guides were so kind and helpful, even finding shells for us. We saw so many dolphins too.

Response from Host, Jul 2026

We're so excited that you found that awesome shell! Thanks for the great review!

Captain was funny,...

Craig_P, May 2026
Captain was funny, knowledgeable, and it was a smooth ride. Plenty of dolphins, manatee, and sea shells. Snorkeling was great and kids 7 and 10 had a blast.

Response from Host, Jul 2026

Thank you!

Fun family excursion!

Melanie_D, May 2026
Great experience and so much fun! Captains John and Jennifer were fantastic and entertaining. We wish we could’ve stayed longer! Shell island is simply beautiful. Suggest to bring a bag for the shells you collect! We forgot one, but someone offered an extra.

Response from Host, Jul 2026

Thank you so much for the great review!

Go! Our age of 82 and 78 was no problem as they were helpful getting on and off the boat.

Patricia_H, May 2026
We were prepared because we were told what to bring. Captain John was a delight. The wildlife he pointed out was nice.

Response from Host, Jul 2026

This is so wonderful! Thank you!

All day!

heather_g, May 2026
What a great, kind, and family owned operation! Capt John and his first mate Katie were wonderful. They were fun and knowledgeable about the area and local wildlife. We enjoyed our morning shelling/snorkeling so much that we asked if they had room for us to go out with them again on the later snorkeling cruise. We spent the whole day with them on the Calypso Cat and had so much fun and found lots of shells. 10/10 would recommend.

Response from Host, Jul 2026

WoW! Thank you! Both trips are fun and offer a different variety. I'm so glad you opted to enjoy them both! We hope to see you out with us again soon!

Best 2.5 hr local day cruise!

B_C, May 2026
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!

Response from Host, May 2026

We love Shell Key! Thank you so much for the great review!

Great experience!

Sarah_P, May 2026
The crew was friendly, funny and accommodating! We saw quite a few dolphins, including a few newborns and the beach to collect shells was beautiful! Highly recommend!

Response from Host, May 2026

Thank you for the 5 stars!

Perfect family activity

Rachel_H, Apr 2026
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!

Response from Host, Apr 2026

So cool that the dolphins came so close! Thanks for the great review!

Chick_C, Apr 2026
Fun little cruise. Saw plenty of dolphins and even 5-6 manatees! The 2 person crew knew their stuff and were fun to travel with!

Response from Host, Apr 2026

We love it when the manatees come to say hi! Thanks for the kind compliments and the 5 star review!
