Ocean Path trail, as its name suggests, is mostly a flat walkway along the southeast coastline of the Mount Desert Island. The trail is rated easy/beginner level with nice ocean view throughout. We thought it would be a great starting hike to explore Acadia National Park.
The trail starting from Sand Beach to Otter Point is about 4 miles back and forth. If you would like to explore some of the side tracks and take lots of photos, it could easily take 2-3 hours. We were a bit short on time so decided to do the trail half way from Thunder Hole to Otter Point.
