Must-Do Activities


One HHI, Five Stars!

Great Trip!!

We took our 3 young children (11, 7, and 7) on this dolphin tour. They loved it! We saw so many dolphins!!! It was so much fun going from side to side to see them! Even though it was scorching hot, the boat is covered and of course you get a good breeze when it is moving.

Pilot your own skiff!

This was a lot of fun. When was the last time you drove a boat? You'll get to on this tour. My husband and I took turns driving (but mostly it was me!)It was very comfortable, much less jarring than the Creek Cats and there is a canopy so we were in the shade the entire time.

Creek Cat Tour was an awesome!!!

My husband and I went out on the 8 AM Creek Cat tour led by Jack and had a great time. We have been coming to Hilton Head collectively for over 65 years and have done numerous adventures on the island, land, sky, and sea, and this was something new and different for us.

Great tour!

Gideon did a great job of explaining what to do beforehand and he was very knowledgeable of the area. We were fortunate to be the only family on the tour so Gideon took his time giving us a little history of the island and the ecosystem nearby. He answered any questions we had.
