Reducing Congestion

The Island Explorer is a fare-free, seasonal, propane-powered bus system that runs through Acadia National Park and its surrounding gateway communities.

The Island Explorer is a long-running success, carrying millions of passengers since its inception and helping hikers enjoy car-free trips in Acadia.

Friends of Acadia has been involved with the bus system since the beginning, helping to fund and spearhead the initial test routes and facilitate major gifts from L.L.Bean and other donors to enable continued growth of this innovative transportation system. The Island Explorer receives funding from the state and federal government, as well as grants from L.L.Bean, Friends of Acadia, local towns, businesses, and passenger donations.

As use of the Island Explorer has expanded, additional routes have been developed. The system is expected to grow as Acadia National Park’s transportation plan is implemented. Friends of Acadia is excited to work with partners to facilitate future access to Acadia via public transportation.
