Rain in Bar Harbor is not a disaster. It is a redirect. The town has more going on indoors and in bad weather than most visitors realize, and some of the best experiences on Mount Desert Island actually improve when it is wet out. Jordan Pond House is less crowded. Whale watches still run. The museums have room to breathe. A rainy day in Bar Harbor is not a wasted day. It is just a different kind of day.
Here are 15 things worth doing when the forecast turns gray.
1. Abbe Museum
The Abbe Museum at 26 Mount Desert Street is the best museum in town and one of the better small museums in New England. It focuses on the Wabanaki Nations, the Indigenous people who have lived in this region for over 12,000 years. The permanent collection includes birchbark canoes, baskets, tools, and contemporary art. Rotating exhibits change a few times a year and are consistently well-curated. Admission is $10 for adults, $5 for kids 6-15. Budget about an hour, maybe more if the current exhibit hooks you.
The Abbe has a second location inside Acadia National Park at the Sieur de Monts area, but the downtown museum is the larger and more complete experience. Start there.
2. Atlantic Brewing Company
Atlantic Brewing is at 15 Knox Road in Town Hill, about a 10-minute drive from downtown Bar Harbor. Free tastings. The blueberry ale is the one everyone tries first, and it is legitimately good, not syrupy sweet like most fruit beers. They also make a solid coal porter and a real ale series that rotates. The tasting room is casual and the outdoor area works if the rain lets up. No food kitchen on site, but food trucks park outside in summer.
3. Criterion Theatre
The Criterion at 35 Cottage Street is an Art Deco movie theater built in 1932 that still shows films. The interior is the real draw: ornate plasterwork, a balcony, vintage fixtures, and a stage that hosts live music and comedy in addition to indie and first-run films. Ticket prices are reasonable. Check their schedule online before you go. On a rainy evening, watching a movie in a theater this beautiful feels like something out of another decade, because it is.
4. Shopping on Cottage Street and Main Street
Bar Harbor has actual shops worth browsing, not just t-shirt outlets. Sherman’s Books on Main Street has been around since 1886 and stocks Maine authors, maps, and trail guides alongside a full bookstore. Cool as a Moose is the souvenir shop that locals will admit to liking. Island Artisans is a co-op gallery with work by Mount Desert Island artists, including pottery, jewelry, and woodwork. The two streets together take about 90 minutes to walk if you are serious about it, less if you are just killing time before dinner.
Sherman’s has a great selection of USGS topographic maps and Acadia trail maps. If you are planning hikes for later in the trip, this is where to stock up.
5. Jesup Memorial Library
The Jesup Memorial Library at 34 Mount Desert Street is a free public library with a reading room that overlooks a garden. It is small, quiet, and beautiful. The building itself is worth seeing, with wooden beams and windows that let in soft light even on cloudy days. They have Wi-Fi, comfortable chairs, and a good collection of Maine history and nature writing. No one will bother you. If you just want to sit somewhere warm and read for an hour, this is the spot.
6. Whale Watching
Rain does not cancel whale watches. Bar Harbor Whale Watch Co runs trips out into the Gulf of Maine in everything short of a gale. The whales do not care about the weather, and frankly, some of the best whale watching happens in overcast conditions when the water is calmer and the glare is gone. Dress in layers, bring a waterproof jacket, and expect to get damp. Trips run 3 to 4 hours. Humpbacks and finbacks are the most common sightings from late May through October.
Sit on the upper deck even in rain. The enclosed lower cabin gets stuffy and the motion is more noticeable down there. Seasickness is worse when you cannot see the horizon.
7. Diver Ed’s Dive-In Theater
This one is unique. Diver Ed’s operates out of the College of the Atlantic campus and puts a diver with an underwater camera into the cold waters off Bar Harbor while you watch the live feed on screens above. He narrates what he finds: sea urchins, starfish, crabs, lobsters, whatever shows up. The audience reacts like it is a nature documentary happening in real time, which it is. Great for kids and honestly entertaining for adults too. Runs seasonally. Check the schedule.
8. Jordan Pond House Popovers
The Jordan Pond House inside Acadia National Park serves popovers and tea on the lawn, but on a rainy day you eat inside, the wait is shorter, and the experience is more relaxed. The popovers are light, eggy, hollow pastries served with butter and strawberry jam. They have been the thing to order here since the 1890s. Lunch is solid too. Arrive by 11 for the best shot at walking in without a long wait.
The drive along Park Loop Road to Jordan Pond House in the rain is actually gorgeous. Fog sits in the valleys, the granite gets dark, and the forest looks like something from the Pacific Northwest. Bring a camera.
9. Hulls Cove Visitor Center
The Acadia visitor center at Hulls Cove has a free 15-minute orientation film about the park that is well produced and worth watching, especially if this is your first visit. Rangers give talks throughout the day on topics from geology to wildlife. The bookstore is stocked with field guides, maps, and Acadia-specific books. This is a good 45-minute stop that resets your trip planning and helps you figure out what to do once the weather clears.
10. Seal Cove Auto Museum
On Pretty Marsh Road, about 20 minutes from downtown Bar Harbor on the quiet western side of the island, the Seal Cove Auto Museum has over 100 antique cars and motorcycles. The collection leans early 1900s through the 1930s. Brass-era cars, early Fords, steam-powered vehicles, and vintage motorcycles are displayed in a clean, well-lit space. Even if you are not a car person, the craftsmanship is impressive. Open seasonally, usually May through October. Admission is about $10 for adults.
Seal Cove is a 20-minute drive from downtown, which means the parking lot is never full. Combine it with a drive around the quiet side of the island. Stop at Southwest Harbor for lunch at Beal’s Lobster Pier on your way back.
11. Shore Path in the Rain
The Shore Path is a 0.75-mile waterfront walkway that starts behind the Bar Harbor Inn and follows the edge of Frenchman Bay south past grand old summer cottages. In the rain, the path empties out and the bay takes on a moody silver quality that photographs better than sunshine. The cobblestones can be slippery when wet, so wear shoes with grip, not flip-flops. Fifteen minutes out, fifteen minutes back. Free. No reservation needed. One of the best short walks in town, weather or not.
12. Side Street Tavern
Side Street Tavern at 49 Rodick Street is the kind of place that makes a rainy afternoon feel intentional. The lobster mac and cheese is the order that put them on the map. The haddock chowder is thick and good. The dining room is small and warm, and on a stormy day it fills with people who look like they are exactly where they want to be. No reservations, so expect a wait at dinner, but lunch is easier.
13. Galleries on Main Street
Bar Harbor has a real gallery scene that goes beyond the tourist shops. Alone Moose Fine Crafts on West Street carries handmade work by Maine artisans: pottery, blown glass, wood bowls, and jewelry. Eclipse Gallery on Main Street shows fine art and sculpture in a bright, well-curated space. There are half a dozen other galleries within a few blocks. You can spend an hour walking in and out of them without spending a dollar, or you can spend a lot of dollars. Either way, it is a good way to pass a gray afternoon.
14. Lulu Lobster Boat Ride
The Lulu operates from 55 West Street on the Bar Harbor waterfront. It is a real lobster boat, and the captain hauls actual traps during the ride, pulls up whatever is inside, and explains the whole operation. You will also see seals, harbor wildlife, and the Porcupine Islands from the water. The trip runs rain or shine. It is about 90 minutes and family-friendly. Dress warm. The harbor is cold even in July.
15. Acadia Night Sky Festival Planetarium Events
This is a fall-only note for trip planning. The Acadia Night Sky Festival happens in September and includes planetarium shows, telescope viewing, and astronomy talks. If rain cancels the outdoor events, the planetarium program at the College of the Atlantic moves indoors and becomes one of the best things to do during the festival. Worth building into a fall trip if you are planning ahead.
If you are visiting in September or early October, check the Acadia Night Sky Festival schedule before booking. The festival runs about four days and most events are free or low-cost.
Making the Most of a Rainy Day
The honest truth is that rain in Bar Harbor is not rare. The island averages about 55 inches of precipitation a year, and summer fog can settle in for a full day. Do not fight it. A rainy day is a good day to eat well, browse the shops, catch a museum, and save the hiking for tomorrow. The trails will be better for it.
Does it rain a lot in Bar Harbor?
Bar Harbor averages about 55 inches of rain per year, and fog is common from June through August. Plan for at least one or two rainy days during a weeklong trip. The rain is rarely all-day though. Morning drizzle often clears by afternoon, and the reverse is also true.
Are Acadia trails safe when wet?
Most Acadia trails are safe in rain, but the iron-rung trails (Beehive, Precipice, Jordan Cliffs) become genuinely dangerous when wet. The granite gets slick and the metal rungs are hard to grip. Stick to lower-elevation trails like Ocean Path, Jordan Pond Path, or the carriage roads on rainy days.
Can you still do whale watching in the rain?
Yes. Bar Harbor whale watch boats operate in rain unless there are high winds or severe weather. Dress in waterproof layers and bring a hat with a brim. The whales are just as active in overcast conditions, and some regulars say sightings are actually better when the glare is off the water.
What should I pack for rainy weather in Bar Harbor?
A good rain jacket is essential. Bring waterproof shoes or hiking boots, a packable rain layer for the backpack, and an extra dry layer for after getting wet. An umbrella works in town but is useless on trails. A dry bag for your phone and camera is worth the $10 investment.
