In 2021, the EID Board of Directors declared Earth Day (April 22) an annual day use free access day at Sly Park Recreation Area. All fees associated with day use activities will be waived for guests on this day and for future Earth Days. For 2022, Earth Day falls on a Friday. Camping fees will remain in effect, along with all other policies and procedures.

Jenkinson Lake, at the heart of Sly Park, is surrounded by over nine miles of trails that accommodate hikers, bikers and horses. Scattered throughout the park are a variety of day use areas which are excellent picnic or cookout locations.

All day use areas are in close proximity to the lake and have access to picnic tables, restrooms and water. Sly Park has something for everyone and is open to the public year round.
