About Marathon & “The Outpost”


The early 1800’s saw Bahamian farmers settling in the Vaca Keys, now Marathon, which encompassed several islands including what we know today as Grassy Key. But the island, Grassy Key, has only been “on the map” as accessible to travelers since the early 1900s during the era of Henry Flagler’s ambitious railroad. A ferry connected a few islands to the lowers until the 1930’s when an extension of our famed Overseas Highway put all of Marathon on the map for travelers driving from Miami to Key West.


Grassy Key Outpost, est. 2013, is on the site of the landmark Marathon restaurant, Grassy Key Dairy Bar. And like then it reflects Marathon area history and is known for its local color — as well as colorful characters. Since the early days it’s been a popular respite for comfortable dining and good take-out food for travelers. It is known as a local haunt for residents seeking breakfast, lunch, dinner or just a welcome smile and an ice-cold beer.



"Grassy Key Outpost is a little treasure."

The only thing better than being able to spend a day at the beach in Marathon, is being able to stop at the Grassy Key Outpost on the way there to get supplies for the beach and again on the way back north to order appetizers and cold beer on the patio...This looks like a hole in the wall kind of place, but the food really is gourmet quality. The staff is very friendly and helpful. The restaurant/market is clean and fresh, and the variety of menu items and convenience items is excellent. We've made the Grassy Key Outpost a regular stop and recommend it highly.
