Marathon Key is located in the middle of the Florida Keys and is a great island for a laid back vacation. You’ll get more of a ‘locals’ feel than you would at some of the more touristy keys.
What to See in Marathon Key:
Seven Mile Bridge
Sombrero Beach
Bahia Honda State Park
The old Seven Mile Bridge
Take a snorkeling tour
Watch the sunset
Turtle Hospital
Stand up paddleboarding or kayaking
Restaurants in Marathon Key:
Burdines Waterfront was our go to. It was one of the first places we ate and we loved the casual waterfront atmosphere and the simple delicious food so much we went back 2 or 3 more times! Sunset Grille & Raw Bar, Castaway Waterfront Restaurant, and Sweet Savannah’s for ice cream.
Must Eats in Marathon Key:
All the key lime things (pie, ice cream, fried key lime pie, chocolate dipped) but also conch fritters, lobster bisque, blackened hogfish, and other seafood.

1 Day Marathon Key Itinerary
See the Seven Mile Bridge at the southernmost point of the key.
Take a snorkeling tour. There is nothing that says ‘The Keys’ to me quite like really good snorkeling. And as much as we enjoyed snorkeling around the beaches (and we saw flounder, colorful fish, and several urchins), it did not compare to the snorkeling excursion.
For dinner: Sunset Grille if you like a party atmosphere and fun drinks, Castaway for a marina experience, or Burdines for something small and casual. After dinner, take your key lime pie to go and watch the sunset at Sombrero Beach.

3 Day Marathon Key Itinerary
Day 1: Rent paddleboards or kayaks. After lunch, check out the turtle hospital. Get ice cream from Sweet Savannah’s. Watch the sunset from the point of end of Marathon and look out over the old Seven Mile Bridge.
Day 2: Visit Bahia Honda State Park. Take the nature trail to the Old Bahia Honda Bridge or view it from the beaches on that end of the key. Snorkel gear and kayaks can also be rented here. Bring a picnic lunch or visit the snack bar.
Day 3: Take a snorkeling tour. Have dinner on the water. Then watch the sunset from Sombrero Beach. Preferably with key lime pie.

2 Day Marathon Key Itinerary
For a 2 day itinerary: Merge days 1 and 2 above. Spend the morning at Bahia Honda State park either snorkeling or kayaking. Get ice cream and check out Seven Mile Bridge.
