Best time to go on a road trip from Boston to Acadia National Park and Bar Harbor

The road trip from Boston to Acadia National Park and Bar Harbor is definitely best enjoyed when the weather is pleasant - the mountainous terrain of the park can make the temperature rather unpredictable, so keep an eye on the forecast before taking off.

When it comes to a summer visit, the good news is that temperatures will often reach a comfortable 70-or-so degrees. That said, this also means you can expect flocks of tourists all over the park, so you may want to steer clear if you're looking for a quiet trip.

On the other extreme, most of the park's services and amenities are inaccessible in the winter, and the freezing temperatures don't help either. If you really want to see Acadia during the snow season, your best bet for accommodation would have to be Bar Harbor itself.

Although spring should be a good time to visit in theory, you'll often find that there's residual snow left over from the winter. Still, if you've been keeping tabs on the weather and you think you're coming up on a warmer spring, you can expect a fairly empty park and low prices.

The best time to visit would have to be fall, though - beautiful sights, declining prices, and a relative lack of tourists makes this a great time to go hiking and sightseeing in Acadia. Be sure to check out Cadillac Mountain for some of the most epic views along the East Coast!
