Essential Acadia: Top 5 Things To Know Before Visiting

Since time immemorial, Native American peoples have inhabited the land now called Maine. Acadia National Park continues to be a place of enduring and immeasurable importance to the Wabanaki, People of the Dawnland. Resistant and resilient, Wabanaki people are still here. We gratefully acknowledge the Houlton Band of Maliseet Indians, Mi’kmaq Nation, Passamaquoddy Tribe at Motahkokmikuk, Passamaquoddy Tribe at Sipayik, and the Penobscot Indian Nation on whose ancestral homelands we now gather.

Your Safety Starts With You

All natural areas pose risk. Your safety depends on your own good judgement. Before setting out on the park’s hiking trails, carefully research hazards and challenges along your planned route. Please do not rely on your cellphone as a map or flashlight. Always carry extra water, a detailed map, warm layers, and foot traction as conditions warrant. Bicycles and horses are not allowed on hiking trails. Check for trail closures and current conditions at

Only Class 1 E-bikes are allowed on carriage roads. Motorized vehicles and Class 2 & 3 E-bikes are prohibited. In winter, please avoid trampling groomed ski tracks.

Take Only Memories, Leave Only Footprints

Please leave Acadia as you find it. Walk only on designated trails and durable surfaces. Pack out trash and pet waste. Secure food and keep your distance from wildlife. Do not stack rocks or alter cairns used for trail navigation. If you discover a cultural artifact, leave it in place, snap a picture, note the location, and tell a park ranger. Learn more at
