Cayo Costa is one of our favorite places to go to! This island is only accessible by boat or ferry. Check out https://www.cayocostaferry.com/punta-gorda.html for ferry rides. Once on the island a tram will stop and pick you up and take you across the island to the beautiful beaches and trail systems. You can can rent kayaks and paddle boards! This island doesn’t have restaurants or stores, so I highly recommend packing a lunch and cooler with cold drinks! . For out of state travelers shoot one of us a text to borrow a cooler or beach supplies, we have plenty :)
