Lake Triangle is a YMCA lake, which limits access to off-camp months, as the campers use the lake everyday when in session. Says Matt
60 acres of skiable land is on hand to the skiers who congregate at Otis Ridge in wintertime; 70% of the ski trails are green and blue while 30% are tough. The 6 feet of good snow that fall per winter at the close by ski resort Otis Ridge is splendid. Otis Ridge has 5 different ski lifts, a splendid 400-foot height difference,
and 11 ski trails. Lots of people from Colebrook come to Lake Triangle, and it's a perfect idea to pop by Doolittle Lake Brook. Going for a hike on the Mattatuck Trail is always a delightful adventure, and go on a trip to Thunder Ridge Farm in the event that you want to ride a horse.
