Wonderland Trail is located on what is called the ‘Quietside’ of Mount Desert Island. This trail is located in Acadia National Park, but in Bass Harbor on the west side of the Island. You will not follow the Park Loop Road to access Wonderland, you will follow Route 102 in Southwest Harbor to Seawall. Wonderland is a flat 1.5-mile hike, with wetlands, forest, and rocky areas. This hike is great for younger children and a favorite during low tide for tide-pooling. Make your trip to Wonderland last longer by packing a picnic lunch and grabbing a picnic table at Seawall or continue to Ships Harbor Trail nearby. Insider Tip: Wonderland is a great rainy day hike!
