What Travellers Say
Reviews Summary
Visitors find Mound Key a unique historical destination, especially for boaters and kayakers drawn to its Calusa heritage and Spanish fort remnants. While the journey is often described as epic and the island feels like a time portal, recent conditions post-Hurricane Ian have made trails overgrown and mucky, with the dock destroyed, impacting the onsite exploration experience for some.
"Kayaked to Mound Key from Koreshan. The trip was nice (5.5 miles one way), but there's really nothing to see at Mound Key as far as we could tell. We went to the south side of the island where the dock used to be. The pilings are there, but the area is overgrown. We tried pulling up to see if we could find the old trail but gave up after about 100 meters. Lots of branches and muck to walk through."
Steven Chorma
"Rented a pontoon boat to get there. And it was epic, a narrow channel into the island that was once a channel through it in ancient times makes for a landing perfectly for a pontoon boat. Walking the island was mostly difficult and so we didn't really. But still approaching and landing on the island was a major bucket list on our sailing trip this winter ok Dragon's Lair."
Captain Bob Hartzell
"This was the Calusa capital city.
• Built almost entirely out of millions of seashells, bones, and sediment — by hand.
• The central mound rises 30+ feet above sea level.
• Believed to be the ceremonial and political headquarters of the Calusa king.
• You can only get there by kayak or boat, making it feel like a time portal.
• Spanish explorers (like Ponce and Menéndez de Avilés) visited here in the 1500s."
