About Oli's Trolley
Oli's Trolley is Bar Harbor's best-known narrated sightseeing tour company, operating distinctive open-air trolley vehicles through Acadia National Park and around Mount Desert Island. Since 1986, they've been giving visitors an accessible, entertaining introduction to the park's highlights — from the summit of Cadillac Mountain to Thunder Hole, Jordan Pond House, and the scenic Park Loop Road. Their trolleys are a familiar sight on the roads of Acadia, and many repeat visitors to Bar Harbor consider an Oli's Trolley tour an essential part of the experience.
Their tour lineup includes the flagship 2.5-hour Acadia National Park tour, which covers all the major stops with narrated commentary on the park's history, geology, and ecology. A separate Cadillac Mountain sunset tour times the visit to coincide with one of the most celebrated sunsets on the East Coast. For visitors who prefer a slower pace, their one-hour trolley tour through Bar Harbor's historic village district covers gilded-age cottages, the town's maritime heritage, and waterfront views. All tours depart from downtown Bar Harbor with convenient pickup options at major hotels and campgrounds.
What makes Oli's Trolley a standout is the quality of their narration — drivers are trained naturalists and local history buffs who deliver engaging, informative commentary that goes well beyond a standard tour script. The open-air trolley format allows passengers to feel the breeze and hear the ocean, creating an immersive experience that enclosed bus tours can't match. For visitors with limited time in Acadia, Oli's Trolley provides the most efficient and enjoyable way to hit all the highlights without navigating the park's congested roads and limited parking.
