Adams Key Loop Trail

Overview

This is a very short, easy 0.5-mile loop through the wooded interior of Adams Key, a small day-use island in Biscayne. Plan on about 15 minutes total. The tread is smooth dirt with some grass and no elevation to speak of—simple, flat, and straightforward.

What You’ll See

Don’t expect water views. The path stays under closed-canopy maritime forest the whole way, offering shade but little variety. Think maritime hammock on coral limestone, with dense subtropical greenery. There are no notable overlooks, historic markers, or standout features along the loop itself—just a quiet forest walk.

Access and Facilities

Adams Key is boat-access only. The island has a dock, picnic pavilion, and restrooms, but it’s day-use only (no camping). The loop is not wheelchair accessible; the dirt surface can be soft enough for wheels to sink.

Is It Worth It?

As a hike, not really. Most visitors find it underwhelming—short, no vistas, and the mosquitoes can be brutal. Treat it as a shaded leg-stretcher while you’re already on the island for a picnic or water-based activities. The real draw here is being out on the water, not this walk.

Best Time to Hike

Year-round access, but mosquitoes are persistent in every season. Cooler, breezier months (late fall through early spring) may take the edge off, yet bug pressure can still be intense. If you’re here, do the loop quickly between paddles or lunch.

Tips

Bring strong insect repellent (seriously) and consider long sleeves and pants. There’s no potable water on this “waterless” island—pack in everything you’ll drink. Set expectations: this is a quick forest loop with no bay views; pair it with paddling, snorkeling, or a picnic to make the stop worthwhile.
