Bar Harbor is a small, walkable village of a few thousand residents that sits on the edge of one of the most visited national parks in the United States. That combination is the source of both its charm and its challenges: the scenery is superb, the food is excellent and the history is rich, but the best sights fill quickly in summer and fall, and a few simple decisions made in advance will make your trip smoother. This guide covers what a first-time visitor needs to know.
How the island is laid out
Bar Harbor lies on the northeast corner of Mount Desert Island, which is joined to the mainland by a short causeway near Trenton. Most of Acadia National Park occupies the eastern and southern parts of the island, and the 27-mile Park Loop Road is the main scenic route, running from near the Hulls Cove entrance past Sieur de Monts, Sand Beach, Thunder Hole, Otter Cliff and Jordan Pond. Cadillac Mountain rises in the middle. The western side of the island, around Somes Sound, Southwest Harbor and Bass Harbor, is called the quiet side. The Schoodic Peninsula, the park's mainland section, is about an hour away across Frenchman Bay.
Passes and reservations
An Acadia entrance pass is required year-round, and you can buy a vehicle pass at machines and entrance stations or online ahead of time. Passes are valid for several days, so you buy once for your stay. In the main season, from late May to late October, driving a private vehicle up Cadillac Summit Road also requires a timed vehicle reservation, sold in advance online and in a smaller batch closer to the date, with sunrise slots in higher demand. Guided tour operators have their own commercial arrangements, so tour guests generally do not buy the summit reservation themselves. Ask when you book whether the park pass is included.
Getting around without a car
Bar Harbor itself is walkable, and the free Island Explorer shuttle buses connect the village with the park, trailheads, carriage road entrances, Jordan Pond and Sand Beach in season. The shuttle does not go to the Cadillac summit. Narrated trolley tours cover the Park Loop Road, and a downtown trolley loop gives a quick introduction to the village. If you do bring a car, remember that parking at Sand Beach, Jordan Pond and Thunder Hole fills early on sunny days, so start before nine or after three.
What to book ahead
In July, August and the first half of October, book your accommodation months in advance and reserve tours the moment your dates are fixed. Whale watches, sailing trips and trolley tours sell out on busy days. A table at Jordan Pond House can be reserved only in a limited number, so plan on a wait unless you go at off-peak times. Cadillac sunrise slots are the most difficult reservations of all.
Weather and clothing
The Maine coast is cool and changeable. Even on a warm July day the summit of Cadillac Mountain can be windy and chilly, and boat trips are colder than the town. Pack layers, a windproof jacket, sturdy walking shoes and a hat. Fog is common in early summer and can hide views for hours, so keep plans flexible and treat foggy days as an opportunity for museums, the downtown trolley, gardens and food.
Must-do list for a short stay
If you have only one day, take a narrated Acadia trolley tour or drive the Park Loop Road with stops at Cadillac Mountain, Thunder Hole and Jordan Pond, then walk the Shore Path at the end of the day. With two days, add a boat trip, the carriage roads or a hike, and a quiet-side drive to Bass Harbor Head Light at sunset. With three days, see the three-day itinerary guide on this site.
Eating well
Try lobster in some form, whether a roll on a picnic table, a boiled dinner at a lobster pound or a tasting on a food tour. Look for blueberry pie, popovers at Jordan Pond House, chowder and local ice cream. Restaurants in Bar Harbor can be busy in the evenings, and many take reservations only for larger groups, so eat early or late, or have lunch as your main meal.
Respecting the place
Acadia is crowded in peak season, which puts pressure on fragile habitats and the people who live and work here. Stay on marked trails, carry out your trash, give wildlife a wide berth, keep a safe distance from surf at Thunder Hole and watch the tide on Bar Island. Support local businesses and be patient in lines and traffic. A little courtesy goes a long way in a small town at its busiest.
A sample first day
Start with coffee and a pastry in the village, then join a morning trolley tour of the park. Have an early lunch in town or at Jordan Pond House, spend the afternoon on a boat or the Shore Path, and finish with a lobster dinner and a stroll past the harbor lights. Whichever combination you choose, build in slack for traffic, weather and the simple pleasure of sitting on a bench and watching the bay.
