Tucked in the heart of the Florida Keys, Marathon feels like the perfect blend of laid-back island living and nature excursion. This 10-mile-long city stretches across 13 islands about an hour away from the famous Key West. It's home to Sombrero Beach, one of the most spectacular beaches in the Florida Keys, as well as some of the most fascinating coral reefs in the state.
Marathon has everything you need for an activity-packed vacation. The historic Old Seven Mile Bridge, now a pedestrian path to Pigeon Key, offers sweeping ocean views and a great place to cast your fishing line. This stretch was once part of Henry Flagler's early-1900s railway, and is listed on the National Register of Historic Places. There's even a tram tour ($28) to Pigeon Key for history buffs who'd like to learn more about the region's backstory. Add in Marathon's coastal parks and nature trails, and you've got postcard-perfect backdrops for sunrise beach jogs or bike rides at dusk.
But the real showstopper lies underwater. Marathon is a snorkeling hotspot, perfectly adjacent to Sombrero Reef and Looe Key Reef, both just a short boat ride away — making it one of the most accessible and beautiful snorkeling bases in the Keys. Whether a casual beachgoer or serious reef-diver, Marathon's sandy shores and historic charm offer everything needed for a memorable Keys adventure.
Marathon is a snorkeling paradise in the Florida Keys
When it comes to beaches and snorkeling around Marathon, visitors have a plethora of options. Sombrero Beach, a sandy stretch with tons of amenities, is often the first stop. It's also a hotspot from April to October for sea turtles coming on shore to nest. Coco Plum Beach is a favorite for visitors looking for a more natural beach experience. Marathon's beaches and parks are dog-friendly, too, so you can bring your pupper as long as they're leashed.
For an amazing underwater experience, head offshore. Local outfitters like Captain Hook's and Spirit Snorkeling offer trips to Sombrero Reef, a National Marine Sanctuary reef system known for colorful coral and tropical fish. A guided snorkel excursion with equipment included will run you around $60. Or venture slightly farther to Looe Key Reef, consistently hailed as one of the area's best snorkel sites. Whether you're scanning the surface or diving deeper, you'll encounter wildlife like parrotfish, eels, barracudas, reef sharks, and more. Both reefs are part of Mission: Iconic Reef, one of the world's largest reef conservation projects.
To mix history and snorkeling, check out some of the shipwreck viewing excursions that take snorkelers along the Shipwreck Trail — nine historic shipwrecks that now serve as artificial reefs. For even more nature exploration, head to Curry Hammock State Park for paddling tours through Florida's famous mangrove ecosystem. This protected natural sanctuary is excellent for bird-watching, too, and paddlers might even spot dolphins or manatees with some luck. Just remember to always protect coral and wildlife when snorkeling or swimming by using coral-friendly products, like this Blue Lizard reef-friendly sunscreen.
Planning your visit to Marathon, Florida
Key West International Airport is the closest to fly into, although roadtrippers can also land at Miami International and drive there in about two hours.To get the most from Marathon, plan your visit around the best weather and visibility. Late spring through summer brings clearer water, calmer seas, and ideal swimming conditions — and it's also just after high season (January to April) winds down, so it's less crowded. The shoulder season in late fall is another great time to avoid crowds, but it may be rainier.
Stay central on the island by booking a waterfront resort, condo, or vacation rental. Most are just minutes from Sombrero Beach and dive shops offering boat charters. Visitors interested in quality water time might enjoy Captain Pips, a waterfront resort and marina with tons of amenities, rentals, and charters available on-site. For swankier digs, Isla Bella Beach Resort is top-rated for its on-site dining, spa, five oceanfront pools, and more. Be sure to reserve snorkeling charters in advance, especially during holidays and high season.
After working up an appetite, enjoy fresh fish tacos or conch fritters at local seafood joints before catching sunset from the bridge or harbor. Marathon is unique for its blend of laid-back, classic Keys vibe, iconic reefs, and hands-on marine conservation. So whether you're looking to experience Florida's best beaches on a scenic road trip or booking a family-friendly getaway, Marathon fits the bill.
