💡 Local Tip
Frequent visitors often use the St. Johns River Ferry at nearby Mayport Village for a scenic shortcut to Fort George Island and Amelia Island, avoiding the longer drive around through Jacksonville.
🚖 Getting There
For commercial flights, use Jacksonville International Airport (JAX), then drive via I-295/FL-9A and Mayport Road (A1A) to the base; the trip usually takes 35-50 minutes. Rideshares, taxis, and rental cars can reach the base gates, but non-DoD visitors must have a sponsor, pass, or prior authorization. JTA bus service serves the Mayport area, but schedules are limited and may not go directly to the airfield.
