Plan this island well

A practical base for the right kind of trip.

Key Colony Beach offers a small island setting close to Marathon’s larger service network. It works well when travelers want a quieter base without giving up quick access to groceries, healthcare and major Middle Keys attractions.

Confirm whether beach, dock, pool or rental access belongs to a specific property. Public and guest-only facilities can sit close together but operate under different rules.

How to use this island page

Treat Key Colony Beach as a quieter Marathon-adjacent base. Confirm public vs guest beach and dock access before you advertise it to the group as “the beach.”

Marathon fishing day

A starter skeleton for a Mid-Keys fishing morning: a charter dock check-in or a City ramp, a bait stop by Boot Key Harbor, a bridge walk as the weather backup and a meal by the water. It does not book a captain, rank charters or promise bait, seats or opening hours.

Charter dock check-in exampleKey Colony Beach MarinaMarina hub on the Sadowski Causeway with charter departures and boat rentals run by separate operators—not a ranking. Confirm which company you booked, the slip and parking with the operator.
Self-launch alternate33rd St Gulf Boat Ramp (City of Marathon)City of Marathon public ramp at 33rd St Gulf, MM 49, open around the clock, if you tow your own boat instead of booking a charter. No overnight parking, and visitors pay to launch and park a trailer; check current fees on the City's public boat ramps page.
Bait and tackleKeys Maritime Bait Shop & Seafood MarketDockside shop at 890 15th Street Ocean, reached from Sister Creek Channel, with live and frozen bait and tackle. Live bait changes daily, so call before you count on it. Skip this stop if the charter includes bait.
Weather backup: bridge walkOld Seven Mile Bridge (Knights Key Trailhead)Knights Key Trailhead at about MM 47 for the restored span toward Pigeon Key. There are no restrooms at the trailhead. Follow the rules posted at the bridge, and check posted roadwork detours near Knights Key.
Meal by the waterSparky's Landing Fish and Cocktails Bar & GrillWaterfront restaurant and bar at 13205 Overseas Highway, behind the Fairfield Inn & Suites. Ask the restaurant whether it will cook a catch you bring in, and confirm hours on its source.

Starter skeleton from directory listings—not a booking, live ops feed or sold ranking. Re-check each source the morning you go.

Practical questions

Using Key Colony Beach without treating every map listing as a plan

Do I still need Marathon if I stay here?

For a full grocery, hospital or airport stop, yes. Key Colony Beach is a compact city with beach and marina access, not a replacement service hub.

Is the beach public?

Some shoreline access is property-specific. Confirm whether the sand or dock you circled is public or guest-only.
