Open Daily:

"Year-Round" during Park Hours 



You can enjoy walking, hiking, running and biking through over twenty-eight acres of restored native prairie flowers, and the trails all disperse from one central location off the parking facility.  All trails are "out-and-back" in design.

Two paved pedestrian/bike trails enter the park alongside the roadways (see our website page on Enter The Park), and the trail at Main Street connects with the McHenry County Conservation District "Prairie Trail Bike Path" which is a convenient access point.  For more information regarding the Prairie Trail Bike Path, please visit

East Trail (.5 Miles)

This meandering .5-mile sandy trail starts by the Marina Building and winds its way along the East Shoreline.  It's a favorite for morning bass fishing, with easy access to the water and one fishing outcrop built from stone.  At the end of the trail is a park bench where you can rest and snap great pictures before heading back.

Peninsula ("West") Trail (.75 Miles)

This is our largest and most popular trail, a .75-mile sandy trail starting at the base of the entrance hill where the switchback blacktop walkway enters the park.  The Peninsula Trail also meanders along the lake and connects to shoreline fishing, two fishing piers and two stone fishing outcrops along the water's edge.  Close to the end of the trail is a shelter with three picnic tables where you can enjoy a picnic (no fires allowed).  This shelter is available on a first-come, first-served basis.  Also, the Board House (paddleboarding and sailboarding) is located off the Peninsula Trail. 

Pet Rules

Dogs are allowed on the trails only (not in the water, picnic grounds, Marina or Lake House) at Three Oaks providing they are kept on a short leash and owner pickup rules are adhered to.  Convenient doggie litter bags and drop stations are provided at the start of the trails.  Also, a doggie water station is available at the water fountain located near the Scuba Zone off the East Trail.
