Indian Key Historic State Park

Indian Key is a small island a short distance off the Overseas Highway near mile marker 78.5, and it holds the ruins of one of the earliest European-American settlements in the Keys. In the 1830s a merchant named Jacob Housman built a wrecking town here, a base for salvaging cargo from ships that struck the reef, and for a few years the island was a busy little port with warehouses, houses, a wharf and a hotel. In 1840, during the Second Seminole War, a raid destroyed the settlement and killed Dr. Henry Perrine, a botanist who had hoped to introduce useful tropical plants to Florida. Today the island is quiet, and visitors walk shaded paths past stone foundations, cisterns and signs that describe what stood where.

There is no bridge, so getting there is part of the adventure. Visitors reach the island by their own kayak, a rented paddle craft or a boat shuttle operated by a local concession, with trips leaving from marinas nearby, such as Robbies. The crossing is short but can be breezy, so check wind and tide before you set out.

Once on the island, a loop trail of about a mile passes the remains of the town plan, a lookout tower and the shoreline. There are few facilities, so bring water, sun protection and insect repellent, and wear closed shoes for rocky ground.

The island is small and the experience is atmospheric rather than dramatic. Interpretive signs describe the wreckers, the Seminole conflict and the plants that Perrine introduced, and rangers sometimes lead tours. Expect heat and mosquitoes in summer, and plan for early morning visits when light is gentle and the air is cooler.

Because Indian Key is a state historic site, you must not disturb artifacts, remove plants or walk off marked paths. Pets are generally restricted, and camping is not allowed, so treat it as a short, respectful half-day trip.For travelers who enjoy history and quiet places, Indian Key is among the most rewarding stops in the middle Keys.

It combines well with the tarpon feeding at Robbies, a kayak paddle through mangrove channels and lunch on the water afterward. If you have limited time or do not want to cross water, the Windley Key Fossil Reef State Park offers a land-based alternative with a similar sense of history. Confirm access, tour times and any seasonal limits with the park and the shuttle operator before you plan the trip, since conditions and schedules change.

Families with older children who like exploring ruins will enjoy the island, while very young children may find the crossing and the heat tiring. Bring binoculars for the birds that nest around the shoreline, and take your time reading the signs.

The rewards are quiet and subtle, and they stay in memory. Planning around wind, tide and light will improve the day. Aim to paddle across in the calmest part of the morning, and check the return tide so you are not fighting a strong current. A lightweight long-sleeved shirt, a brimmed hat and a refillable bottle of water are more useful than any gadget.

Take time at the old cistern and the lookout, where views extend across the bay to the highway and the small mangrove islands beyond. Respect the island by carrying out everything you carry in, and consider reading a short history of the Second Seminole War before you go so the ruins make more sense.
