Dry Tortugas National Park
Seven coral islands scattered across open ocean seventy miles from the Florida mainland.
The Gulf of Mexico stretches unbroken to every horizon, interrupted only by these small coral and sand keys rising barely above the waves. Fort Jefferson's massive brick walls emerge from Garden Key like a mirage, while shallow turquoise waters reveal seagrass beds and coral patches beneath your boat. The isolation feels absolute—no power lines, no distant shores, just the endless rhythm of waves against coral rubble beaches.

The Gulf's deep blue contrasts sharply with turquoise shallows as afternoon light penetrates clear water to illuminate coral formations twenty feet below.

Stars reflect off calm waters with no land-based light pollution for hundreds of miles, while waves gently lap against coral shores.
