Indian Key Historic State Park

Accessible only by boat or kayak, Indian Key Historic State Park sits on an 10-acre island in the turquoise waters off Islamorada in the Florida Keys. This isn’t your typical state park — it’s a place where history and tropical beauty collide in a way that feels almost cinematic.

In the 1830s, Indian Key was a thriving settlement and the original county seat of Dade County, complete with a hotel, warehouses, and streets. That all ended in 1840 when a Seminole raid destroyed the village. Today, the foundations of those buildings still poke through the tropical vegetation, and interpretive signs guide you through the ruins along well-maintained trails. The observation tower at the island’s highest point offers sweeping views of the surrounding Keys and shallow flats.

Snorkeling in the surrounding waters reveals healthy coral formations and a surprising variety of marine life for such a shallow area. Kayaking to the island from Robbie’s Marina or Lower Matecumbe Key is one of the most popular ways to arrive, and the paddle itself — across gin-clear flats where you can spot rays, nurse sharks, and sea turtles — is half the experience.

There are no camping facilities on the island, so plan this as a day trip. Bring water, sun protection, and sturdy shoes for walking the coral rock paths.

The best time to visit is November through April, when temperatures are mild and humidity drops. Arrive early to beat afternoon winds that can make the paddle back choppy.
