Tampa to Sea Island Road Trip: Ultimate Coastal Drive Guide

Route 275 North meets I-75 near downtown Tampa, a convergence that has funneled travelers toward Georgia's Golden Isles for decades. This 280-mile journey from Tampa, FL to Sea Island, GA typically takes 4.5 to 5.5 hours of driving, but savvy explorers extend it to a full-day adventure. The route crosses the Suwannee River, a designated National Wild and Scenic River, making it one of the few blackwater rivers in the US with protected status.

I-75 is generally safe, with an accident rate of 0.6 per million vehicle miles. Watch for wildlife near Paynes Prairie and dense fog in the Suwannee River basin. Family-friendly stops include the Children's Museum in Ocala and the Georgia Sea Turtle Center on Jekyll Island. For pet owners, Gainesville's dog parks and St. Marys' pet-friendly waterfront are ideal. Fatigue management is crucial; take a break every 2 hours at designated rest zones like the Alachua County Rest Area (mile marker 399) or the Georgia Welcome Center (mile marker 1).

• Child-friendly: Silver Springs glass-bottom boat tours, Okefenokee Swamp Park, Sea Island Beach Club.
