Interlake State Recreation Area

Interlake State Recreation Area in Lynnville is a 3,550-acre former coal mine converted to off-road recreation, one of the largest OHV destinations in the Indiana state recreation system. The property's heritage as reclaimed mining land is what makes the terrain unusual, the natural elevation, drainage patterns, and surface variety differ from most natural-topography state recreation areas. The trail network covers 100 miles of multi-use trails. The footprint includes rock garden play areas for technical riding, dedicated single-track for dirt bikes and trials work, and 4x4 trails sized for full-size Jeep and truck access. The cross-machine inventory is the operational identity: the same property welcomes Jeeps, trucks, dirt bikes, ATVs, and UTVs, which works for mixed-vehicle family groups doing multiple disciplines on the same trip. Operating model is day-use only with a small fee. Indiana ORV Sticker is required for motorized riding, the state's standard OHV registration program. Adjacent restrooms at the main entrance handle the basic facility needs. No on-site camping; the property runs as a day-use destination. For local riders in Pike and Warrick counties and the broader southwest Indiana region, Interlake is the destination state recreation OHV property. Riders in Lynnville, Boonville, Petersburg, Princeton, Jasper, and the Evansville metro have everyday access to a state-managed legal OHV property. Bloomington and Terre Haute area riders make the trip south for the 100-mile trail network. Owensboro and Henderson (KY) riders cross the river for cross-state legal OHV access. The reclaimed coal-mine heritage is part of the broader Indiana state recreation system's commitment to converting industrial heritage land into public recreation infrastructure. For southwest Indiana, that conversion delivered the area's largest dedicated OHV destination.
