Folsom and Crooked Ponds are connected to each other by a channel and split up into three distinct areas - each surrounded by various species of trees and other vegetation. Folsom Pond is 282 acres in size and 19 feet deep. Crooked Pond is 220 acres and 30 feet deep. They're located just a little ways southeast of the town of Lincoln in between Mattanawcook and Upper Ponds. Access is located around homes and cabins, so be sure not to park or carry on private properties. Be prepared to ward off mosquitoes - especially in spring.
