Things to do nearKeewaydin Island
Keewaydin Island is a pristine, car-free barrier island off the southwest Florida coast, celebrated for its shell-strewn beaches, calm waters, and abundant wildlife.
Keewaydin Island sits within a chain of barrier islands separating Naples Bay and Rookery Bay from the Gulf of Mexico in Collier County, Florida. For most of the twentieth century the island was privately held, which kept development at bay and allowed its natural character to remain largely intact. Today much of it falls within the Rookery Bay National Estuarine Research Reserve, one of the few remaining undeveloped mangrove estuaries on the Gulf Coast of North America.
Visitors come primarily for the beach itself. The Gulf-facing shore is wide and gently sloped, with calm, clear water well suited to wading and swimming. The island's remoteness means the sand is consistently clean and the shell hunting is exceptional. Whelks, olive shells, and the occasional junonia turn up regularly, drawing dedicated collectors who time their visits to the tides.
The interior and bay-side edges of Keewaydin Island support dense mangrove habitat that shelters nesting ospreys, roseate spoonbills, great blue herons, and brown pelicans. Kayakers and paddleboarders often explore the quieter bay-side channels, where the water is shallow and the birdlife is close. Water-taxi and charter-boat operators based in Naples and Marco Island offer scheduled and private runs to the island, making access straightforward even without a private vessel.
Keewaydin Island rewards visitors who appreciate a place that asks little of you beyond attention. There are no curated attractions here, only the rhythm of tides, the geometry of shells, and a coastline that looks much as it did long before the mainland to the east was built up. For anyone seeking a genuine natural escape within reach of a major Florida destination, it remains one of the region's most compelling day trips.
7-day forecast
Chance of rainTips for visiting Keewaydin Island
Arrive by mid-morning to claim a stretch of beach before the day-trip boats from Naples bring their passengers ashore.
Bring a mesh bag for shelling. Keewaydin Island is renowned among shell collectors, and low tide exposes the best finds along the southern tip.
Pack all food, water, and sunscreen. There are no concession stands or facilities on the island, so everything you need must come with you.
Visit between May and October to watch for loggerhead sea turtle nesting activity along the upper beach, and give any marked nests a wide berth.
Bring water shoes for wading the sandbars on the bay side, where the bottom shifts between soft sand and scattered shell beds.
