Why go by boat

In Marathon, the water is the destination

The Florida Keys look beautiful from the Overseas Highway. They make a lot more sense once you leave the road behind.

A Marathon boat tour can mean getting into the clear water at Sombrero Reef — a protected area of the Florida Keys National Marine Sanctuary marked by the Sombrero Key Lighthouse — or staying above it while Boot Key Harbor, Seven Mile Bridge, and the surrounding islands settle into evening. Both trips begin in the heart of Marathon and put the focus where it belongs: on the water.

The three-hour Reef Snorkel Tour is for guests who want the main event to be underwater. The Sunset Eco History Tour is the easier fit when your group wants Keys scenery, local context, and golden hour without planning a full day offshore.

A real reef day

The Reef Snorkel Tour heads to Sombrero Reef for a three-hour guided outing built around time in the water and views below the surface.

A sunset with some substance

The eco-history cruise pairs Keys color with stories about Marathon's islands, bridges, history, and environment.

Public trips or your own boat

Book a scheduled experience online, or call about a private charter when your group wants a more flexible day on the water.

One experience is built around getting into the water. The other lets everyone enjoy the Keys from the boat.

Reef snorkeling is the main event

The three-hour Sombrero Reef trip is for guests who want time in the water. Review the age, swimming, and participation requirements before reserving for children or less-confident swimmers.

Sunset stays on the boat

The approximately two-hour eco-history trip pairs open-air Keys scenery with local history and ecology, making it the simpler choice for a mixed-age group.
