Located in Westmore, Vermont, Willoughby Lake was carved out by a glacier; the latest findings state it is 357 feet deep at its greatest depth, about 5.5 miles long, and 1 mile wide. Mount Hor and Mount Pisgah tower above its tranquil beauty. During Prohibition, Mount Hor was the site of a secret cave harboring a still, accessible only by boat or on foot. The mysterious Arcadia Retreat was built in a very remote area not easily accessible and was left vacant for many years before burning in 1923. Sentinel Rock is situated on a hill high above Westmore with a tremendous view of the lake and valley below. It has been owned by a few different families over the years—most recently the Wright family, who donated the area to the State of Vermont as a park, so that everyone could enjoy the area. Today, visitors enjoy peaceful canoe rides while others brave the icy cold waters as they run into the frigid lake to raise money for various causes.
