This Is the Most Claustrophobic Hike in Maine—Would You Try It?

I don't know if there's any other state with the kind of hiking that Maine offers. Despite being one of the less-populous states, it's home to some of the country's most beautiful trails, waterways, parks, and, of course, mountains. The Pine Tree State is dotted with gorgeous peaks offering stunning summit views, but some of them require more effort to reach than others. One of the most fascinating hikes in the state is located on Tumbledown Mountain, far away from the most popular hikes in Acadia National Park. This hike offers rugged trails, steep climbs, and a challenging section that might require you to suck in your breath as you squeeze past narrow rock walls.

Tumbledown Mountain definitely isn't for everyone, but if you have the fortitude to brave this challenging path, you'll be rewarded; it's the last obstacle before you reach the summit, and take in one of the most beautiful views in Maine.

An adventure on Tumbledown Mountain is best for experienced hikers. The Tumbledown Mountain Trail, a 5.5-mile loop trail, is rated hard due to its rocky terrain and intense elevation gain of just under 2,000 feet. Bring your best hiking boots and your sense of adventure, because this is an outing unlike any other in Maine!

Many people have made it almost all the way to the summit only to be stopped dead in their tracks at the last leg, when they see the narrow crevice they have to squeeze into in order to reach the summit. This spot has been called the most claustrophobic spot in Maine, and it is also a challenge to get through.

But for those who have taken it, they say it's a rewarding one. This tricky squeeze through the rocks is assisted by iron handrails. This is an official trail marked and maintained by the Tumbledown Public Lands, so it's considered safe to explore. Know your comfort level with narrow spaces, but if you make it through, your reward awaits!

Tumbledown Mountain isn't the highest mountain in Maine, but it does have some of the most beautiful views. Make your way to the summit and enjoy! You'll have to leave the dogs at home for this one, as the trail is considered too steep for them to climb safely, but this truly is an only-in-Maine adventure.
