Bush Key Shoal is a marine shoal located within the Dry Tortugas National Park in the Gulf of Mexico, approximately 70 miles west of Key West, Florida. This is a remote, open-water paddling environment characterized by expansive, shallow sand and coral reef flats. The area is part of a chain of islands and shoals, forming a strategic deepwater anchorage historically guarded by Fort Jefferson. Paddlers will experience clear, emerald-blue to deep blue water over the shoals, with significant exposure to wind and waves from the open Gulf. The primary visual landmark from the water is the massive, historic Fort Jefferson on Garden Key, and a seaplane is a common sight flying over the shoal. Access for paddlers is almost exclusively via private boat or the authorized ferry or seaplane services to the national park; there is no direct mainland launch. Kayakers typically launch from a mothership anchored in the designated anchorage areas, such as near Bush Key Shoal itself, to then paddle in to the park's docks or explore the surrounding shallows. This area is adjacent to major shipping lanes, so paddlers must maintain constant awareness of substantial vessel traffic. The paddling experience is defined by its extreme remoteness, exposure to the elements, and the historical significance of Fort Jefferson. All paddlers must adhere to National Park Service regulations, which govern activities within Dry Tortugas National Park.
