Garden Key Campground is a primitive, first-come, first-served campsite in Dry Tortugas National Park accessible only by ferry or private vessel from Key West (approximately 2. 5 hours away).

The campground offers 8 individual sites accommodating up to 6 people each, with picnic tables and charcoal grills, but campers must bring all supplies including tent, fresh water, food, and fuel—no electricity, running water, or Wi-Fi available.

Fishing and kayaking are permitted with proper licenses and regulations, and the location offers excellent snorkeling, wildlife viewing, and stargazing opportunities, though overnight anchoring for private vessels is limited to designated sand/rubble bottom areas within 1 nautical mile of Fort Jefferson harbor light.
