Naples to St. Simons Island: Ultimate Gulf-to-Island Road Trip

Driving from Naples, Florida to St. Simons Island, Georgia along Interstate 75 and US 17 covers roughly 500 miles—a journey that transitions from the manicured golf-course suburbs of the Gulf Coast to the live-oak-draped barrier islands of the Golden Isles. The route passes through Florida’s Turnpike and I-75 corridor, then east on I-10 to Jacksonville, before veering north on US 17 and finally across the Torras Causeway onto St. Simons Island.

A little-known fact: the stretch of US 17 through Fernandina Beach and into Georgia was once part of the original Dixie Highway, a critical north-south route before the interstate system. Today, this road offers a slower, more scenic alternative to I-95, passing through historic towns and maritime forests.

Best stops along this route include Paynes Prairie Preserve State Park, the Okefenokee Swamp, and the historic districts of Fernandina Beach and Brunswick. The question how long to drive Naples, FL to St. Simons Island, GA is best answered as about 7.5 hours without stops, but with exploration, plan for two days. Is it worth driving Naples, FL to St. Simons Island, GA? Absolutely—the journey itself is a highlight, offering diverse ecosystems and cultural gems.

• Fuel: Gas stations are abundant on I-75 and I-10; US 17 has fewer options between Brunswick and St. Simons, so fill up before leaving the interstate.
• Tolls: Florida’s Turnpike (Naples to Wildwood) uses SunPass or toll-by-plate; no tolls on I-10 or US 17.
• Rest areas: I-75 has modern rest stops every 30-40 miles; US 17 lacks formal rest areas but offers small parks and pull-offs.
