Tumbledown Mountain in western Maine is a well-known hiking destination distinguished by a small alpine pond just below its summit, locally called Crater Lake or Tumbledown Pond. Its appeal lies in the contrast between easier routes that reach the pond and continue along Tumbledown Ridge Trail between the East and West peaks, and much steeper climbs such as the Loop Trail, with cliff views, boulder scrambling, and the narrow passage known as Fat Man's Misery. An even harsher Chimney Trail has long been considered unmaintained and risky. This mix of accessibility, rugged terrain, ridges, cliffs, and summit pond has made Tumbledown one of the region’s better-known mountain outings.
