Bush Key Beach Walk

Overview

A rare treat when conditions line up, the Bush Key Beach Walk is a roughly 1-mile round-trip, out-and-back stroll along the shoreline of Bush Key. It’s flat and entirely on sand, with turquoise water on one side and wide-open Gulf views on the other. Fort Jefferson looms across the channel on Garden Key, adding a dramatic historic backdrop.

Trail Experience

You’ll start from the landing beach area on Garden Key and step onto a natural sandbar that connects to Bush Key when it’s exposed. Expect soft sand, occasional bits of coral rubble, and sometimes a brief, shallow wade if water laps over the bar. The walk is simple and scenic rather than technical, but loose sand can make it a touch slower than a paved path. There are no facilities or shade on Bush Key—everything (water, restrooms, shade) is back on Garden Key—so plan accordingly.

Wildlife and Scenery

This is bird country. Outside nesting season you’ll often see seabirds cruising the shoreline, and photographers will love the open vistas and color contrast of white sand and clear water. During nesting season (typically February through September) Bush Key is closed to protect up to 80,000 sooty terns and 4,500 brown noddies—the only significant breeding colony of these species in the continental U.S. When it’s open, bring binoculars and a camera and give wildlife plenty of space.

Best Time to Hike

Access is seasonal and condition-dependent. The island is generally open from late fall to early winter (roughly October–January) and closed the rest of the year for nesting. Even when open, whether you can walk over depends on the sandbar being above water. Aim for calm conditions and check status the day you visit. The trail is open sunrise to sunset when the island is accessible; cooler temps and softer light typically make mornings and late afternoons the sweet spot.

Logistics and Tips

• Length is about 1 mile total (out and back); most people take 30–45 minutes with photo stops.
• Footwear: water shoes or sandals with sturdy soles work well on sand and occasional coral; avoid bare feet.
• Sun and water: there’s no shade or potable water on Bush Key—pack plenty, cover up, and reapply sunscreen.
• Access: no cars here. You’ll reach Garden Key by ferry, seaplane, or private vessel; the walk begins from the Garden Key landing beach when the sandbar is exposed.
• Leave no trace: there are no trash facilities on Bush Key—pack everything out.

Bottom line: When open and the sandbar cooperates, this is an easy, photogenic coastal stroll with standout birdlife and a surprisingly quiet feel compared to Garden Key.
