8 best eco-friendly hotels in Marathon

Eco-friendly hotels in Marathon offer a practical base for exploring the Middle Florida Keys without compromising on comfort—ideal for travellers who want to cut down on car dependency, support conservation-friendly tourism, and recharge between outdoor days. Marathon’s natural draw includes Crane Point Museum & Nature Center, a 63-acre hammock preserve with museum exhibits and wildlife viewing opportunities, plus the Florida Keys’ iconic conservation work such as the National Key Deer Refuge (Key deer habitat) in the Lower Keys region.

Staying in Marathon suits couples, families, and eco-conscious solo travellers who prefer an efficient itinerary: walkable morning plans, beach-and-bay activities, and minimal detours. In this setting, “eco-friendly” typically means thoughtful energy and water practices, waste-reduction initiatives, and amenities that help guests travel lighter—especially useful for visitors heading out for snorkelling, kayaking, and wildlife-focused attractions rather than spending the day indoors.

For where to stay, look for locations clustered around Marathon’s visitor-friendly centre and marina access, which makes it easier to build low-impact days. Your booking options here range from full-service resorts to quieter, budget-led stays, including Courtyard Faro Blanco Resort (3★) and Fairfield Inn Suites By Marriott Marathon Florida (3★) for a straightforward, facilities-first approach, while Faro Blanco Resort & Yacht Club Marathon, Curio by Hilton (4★) adds a more premium “resort with access” feel. If you’re travelling on a tighter budget, Kingsail Resort (2★) and Coconut Cay Resort and Marina (2★) can still keep your trip centred on the Keys rather than the road.
