If you're going to Acadia, this is a great alternative from the overcrowded frenzy of Bar Harbor, or the overpriced chain hotels/motels around Mount Desert Island. Located just outside Southwest Harbor, this is a quieter corner of MDI with a little village that has a few stores and restaurants (most close at 8pm, so we didn't get to take much advantage). It's about a 15 minute drive from Bass Harbor Light, and about 25 minutes from Bar Harbor, so keep that in mind when planning your visit.
The yurt itself is terrific! Solidly built, with a concrete floor and wood roof ribs, it was remarkably spacious and had all the conveniences of home: modern bath, kitchen, queen bed, couch, and dining table (no TV, which we didn't miss at all.) We stayed in the Beech Mtn yurt, which was set back from the circular drive, offering a bit more privacy than the other yurts.
Most nights, we had a good nights sleep, but there was a rain storm on our final night, which was loud: a reminder that you're staying in a tent, not a solid structure. Also, there is a skylight/oculus centered on the roof, so the light comes streaming in the morning (when we were there, sunrise was at 445am). The hosts do provide eyeshades and earplugs, which do an ok job, but if you're a light sleeper, it might be a challenge to sleep straight through.
Overall, we loved our experience, and would highly recommend to others looking to have a true outdoors stay in one of the most beautiful corners of the northeast.
