An extensive trail system is maintained in cooperation with the Connecticut Forest and Park Association, which provides volunteer assistance. Most hiking trails start and end in the main picnicking area. Each trail is a color-coded loop with the exception of the Nature Trail built by the Youth Conservation Corps. This trail encircles Lake Louise and passes by the pinnacle overlook.
From I-91 North or South: Take Exit 35B which is the Bloomfield Route 218 exit. This road is also known as Cottage Grove Road. Follow Cottage Grove Road heading west until you reach Route 185. Follow Route 185 heading for Simsbury. At the top of the hill, the entrance to Penwood will be on your right.
