Adams Key Loop Trail

Adams Key Loop Trail is a nearly one-mile circuit through the island’s hardwood hammock, starting near the south-side dock and trail sign. The mapped line closes back at its start; the dirt-and-grass path stays beneath trees and is an easy walk with little elevation change. Allow about 30 minutes on foot, apart from the boat trip. Distance descriptions conflict: a trail sign and written account call it a half-mile, while the complete mapped circuit measures about 0.96 mile. This entry follows the full named loop; check the signs at the dock if you expect the shorter segment.

Adams Key is reached by water, and there is no ferry to the island. Arrive in a boat that can land at the island dock, and confirm current launch and landing arrangements before setting out. The island day-use area has a picnic pavilion and toilets. Food service and drinking water were not confirmed, so bring what you need. The pet rule for Adams Key is also unconfirmed; check with the park before bringing a pet.

Adams Key was once home to the Cocolobo Club, a retreat associated with developer Carl Fisher and Presidents Warren Harding, Herbert Hoover, Lyndon B. Johnson and Richard Nixon. The walk itself is through hammock; available accounts do not establish that club buildings or remains stand along the trail.

The route is described as smooth dirt with some grass and remains in the wooded interior rather than following the shore. One account notes that wheels can sink into the dirt, so the easy grade should not be taken as an accessibility guarantee. Water views are not reported from the trail. Mosquitoes are mentioned in a visitor account and a trip description; consider repellent if you are prone to bites.
