What do you want to do in Acadia National Park?

Overall Best Time to Visit Acadia: September & October

If you want to avoid the largest crowds, still have nice weather, and travel when most restaurants (be sure and try lobster rolls) and attractions are still open, the perfect time to visit Acadia National Park is in September and October.

While summer is the popular time to go and you’ll have the warmest weather, the summer crowds can be overwhelming and you’ll pay the highest price for accommodations.

September tends to have nice weather that’s still on the warmer side. You can participate in many of the popular water activities like fishing charters, kayak rentals, and boat tours in the earlier part of the month.

It’s also a fantastic time for hiking the best hikes in the park, including the beehive trail.

In early October, the leaves will start to change, and this is a wonderful time to visit. The crowds will pick up a bit, but it’s not usually as busy as in summer. There’s something about a New England autumn, and you’ll definitely get a beautiful taste for it in Acadia during the early fall.

Best Time to Visit Acadia with Fewer crowds & cheaper prices: November-May

For those who cannot stand crowds and/or want to save as much money as possible, visiting Acadia National Park between November and May is a good option.

Late fall and all through the winter are the park’s off-season, and the number of people who visit Acadia during these months drops significantly. There’s a good chance you’ll be able to experience much of the area with few other people around.

You’ll also pay a lot less for hotels and food during this time of year. While the dining options and accommodations will be limited, the places that are open won’t be busy, and you’ll get to see the quiet, local side that not many tourists have the opportunity to experience.

Best time to Visit Acadia for Good weather: June-September

The best weather in Acadia National Park is between June and September.

This is summer and the temperatures will be warm, and the chances of rain are a lot lower than in the spring. You’ll be able to spend a lot of time doing outdoor activities like hiking, boating, fishing, and biking.

If you want the highest likelihood of warm, sunny days, you’ll want to come between late June and early September.

Best time to visit Acadia for Fall colors: mid-October

While every year is different, peak fall foliage in Acadia National Park tends to occur in mid-October.

This is one of the most popular things to do in Acadia in autumn, and while you won’t be able to predict exactly when the best colors will happen months in advance, if your goal is to see the leaves changing color, you should plan your trip between late September and mid-October.

Best time to visit Acadia National Park for Hiking: June-October

The best time to visit Acadia National Park for hikers is June through October.

The weather is warm and sunny and the snow will have melted, which means the trails will have dried off for the most part and be safe to walk on.

The majority of the hiking trails are open during the summer months, although a few (such as the thrilling Precipice Trail) are closed in the late spring and early summer due to the peregrine falcons nesting. If you want to tackle any of these trails, you’ll want to visit in the later summer or in the fall.

Best Time to Visit Acadia for Biking: June-October

For avid bikers who want to experience the bike paths and the famous carriage roads of the national park, June through October are the best months to visit.

There are miles of carriage roads to explore in Acadia National park. In the spring, many of the carriage roads are closed because they are too wet and need to dry out before they can open up to bikers.

Most of the roads do open by May, but an extra rainy spring could cause a delay, so planning to visit by June is a safer bet.

Best time in Acadia for Horseback Riding: July-October

Horseback riding is a popular activity on the Acadia National Park carriage roads, and if this is something you are interested in, you should plan to visit between June and October.

Just like with biking, the carriage roads need to dry out from the winter before they open for horses, so you’ll need to visit in the summer or fall to participate in this activity.

Best time for Fishing in Acadia National Park: April-September

Fishing is a popular sport around Acadia National Park, and if you’re itching to get out there and catch your own supper, you’ll want to visit between April and September.

There are lots of great lakes and ponds in Acadia that are open to fishing. This can be a fantastic activity and a unique way to enjoy the national park. Some of the most common fish species include brook & brown trout, yellow & white perch, landlocked salmon, and smallmouth bass.

If you want to try your hand at ocean fishing, you’ll need to visit between mid-July and September.

Best time to go Camping in Acadia: Memorial Day-Labor Day

For the outdoor lovers who can’t get enough of sleeping under the stairs, most of the campgrounds in and around Acadia National Park are open between Memorial Day and Labor Day.

This is also when the weather is the best and it won’t be too cold and miserable to sleep outside.

One thing to keep in mind when planning to camp in Acadia: biting bugs start making an appearance in May and June, so if you want to camp in the earlier part of the season, make sure you take this into account and pack plenty of bug spray.

Best time in Acadia National Park for Water activities: June-early September

Since Acadia National Park is right by the ocean, it’s the perfect location for those who want to spend some time on the water. Fishing, kayaking, boating, and whale-watching tours are all popular attractions.

If you want to spend a few days on the water, the best time to visit Acadia National Park is June to early September when these activities are available. Ocean fishing usually happens later in the summer though (July-September), so keep that in mind if you want to do that.

Best Beach days in Acadia: July & August

In the summer, Acadia National Park averages highs in the 70s with July and August being the hottest months. If you want to spend some time laying on the beaches, soaking up the sun, and taking a dip in the water, you’ll want to plan your trip for mid to late summer when the air and water temperatures are the warmest.

Driving Park Loop Road: May-October

Park Loop Road is the popular scenic drive on Mount Desert Island that takes visitors around a portion of the park and to many of the popular tourist attractions. In the winter months, sections of this road close down, so if this is an item on your Acadia bucket list, you’ll want to visit between May and October when the road is pretty much guaranteed to be open.

However, you should always check the National Park Service website for construction and closure notices ahead of time to avoid disappointment.

A free shuttle in the summertime drives Park Loop Road and can pick up and drop off visitors at many of the popular attractions along this route.

If you plan to visit without a car or would rather avoid the traffic, you should come to Acadia in the summer when the shuttle is running.

Sunrise at Cadillac Mountain: May-October

Seeing the sunrise from the top of Cadillac Mountain is one of the most popular attractions in Acadia National Park. If you want to add this to your itinerary, you’ll want to come between May and October. In the off-season, the road closes and you can only reach the summit by hiking, often in snowy and icy conditions.

➡️ Note: if you decide to visit between late May and late October, you will need a vehicle registration to drive up Cadillac Mountain.

Seasons in Acadia National Park

So what is each season like in Acadia National Park? What activities are open during the different times of the year? Here is a breakdown of what you can expect during each season so you can choose the best time to visit Acadia National Park.

Spring (April & May)

Spring is the shoulder season for Acadia National Park. For those who want to avoid crowds and don’t mind some things not being open, it’s a good time of year to visit.

Temperatures in April and May can range from the high 30s to the low 60s during the day and drop into the low 30s and 40s at night. At this time of year, the leaves haven’t started growing back on the trees yet, so there won’t be a lot of green or any flowers yet.

This is also the time of year with the best chance of rain, so if you do visit in the spring, make sure you bring warm rain gear and appropriate footwear. Some hiking trails could still be wet and muddy, and there may still be some lingering snow, although this is more likely in early April than later on.

In the spring, not everything has opened up yet for the season. Many restaurants might still be closed, such as lobster shacks and the famous Jordan Pond House, but you’ll also have fewer crowds in the park and at restaurants and shops.

However, by late April, the carriage roads start to open up to foot traffic and things do start to come alive a bit more in downtown Bar Harbor. The road to Cadillac Mountain should be fully open as well as Park Loop Road. Memorial Day weekend is the unofficial full opening of the park, so almost everything will be open by the last weekend in May.

We visited Acadia National Park in early May and although we didn’t get to experience everything we wanted, we thought it was a great time to go because of the lack of people and the cheaper prices. For a first visit, spring can be a great introduction to the park.

Summer (June-August)

Summer is the most popular time to visit Acadia National Park. This is peak season, which means the most people and the highest prices.

However, everything is open by June, so you can experience just about everything you would want to this time of year. Summer also has the warmest temperatures and the best weather, with highs in the 70s and lows in the 50s on average.

Biting bugs can be a problem in early summer, so keep this in mind as well. Later in the summer, they do start to die down a bit. Also, if you visit Acadia National Park in the late summer, you might find some wild blueberries!

Fall (September & October)

By Labor Day, the crowds start to die down a bit, so autumn is another great time to visit if you want to deal with fewer people in the park and in the towns.

However, there are a lot of people that do come to Acadia to see the fall foliage, so early to mid-October will still have a fair amount of tourists coming to gawk at the stunning colors.

When fall arrives, some things start to close down, but there is still plenty to do. Hiking is fabulous this time of year because the weather is still pretty nice and the leaves are in color. Temperatures will average between the 50s and 60s.

Another thing to note about visiting Acadia National Park in the fall is that cruise ships tend to port in Bar Harbor around this time of year, so the town may be a bit busier when they dock.

Winter (November-March)

If winter activities are something you enjoy, then visiting Acadia National Park from November to March might be for you. Temperatures average between the high 20s to the mid-40s during this time of year, so make sure you pack your warm clothes!

Most attractions and many restaurants and hotels start to close up by the beginning of November. However, this is the low season for the park, so prices will be at the lowest as will the crowds.

Just keep in mind that some of the major tourist spots, like Cadillac Mountain and Park Loop Road, will be closed to cars in the winter, so you’ll have to be content finding other things to do. However, cross-country skiing is great in Acadia, as is snowshoeing, ice fishing, and snowmobiling.
