Mountain Biking is allowed in this area and some new MTB only trails may be on the way soon, however you can ride many areas already even though motorized vehicles are allowed most everywhere. Interlake State Recreation Area (ISRA), former coal mine land straddling Pike and Warrick counties, is a multi-use recreational facility focusing on off-road vehicle (ORV) recreation. Interlake is approximately 3,550 acres with nearly 100 miles of trails and 17 lakes (many of which can be accessed for fishing). The three areas of mining and reclamation create a variety of trail experiences for ORV enthusiasts, horse riders, hikers and mountain bikers. From steep spoil banks to rolling grasslands, man-made lakes and strip pits, Interlake offers a diverse array of topography and scenic views.
