JMF Trails is designed to show the trail system at Jefferson Memorial Forest, located in Louisville, Kentucky. The app uses detailed 7.5-minute topographic maps (showing 10-foot elevation contour lines) as a background for over 35 miles of trails. The maps are incredibly accurate and helpful for hiking, trail running and orienteering. The app also uses the location services (GPS), when available, to show the user location on the trail, altitude (above sea level) and magnetic heading. For those new to the JMF trail system, this is an excellent tool for becoming familiar with the more than 35 miles of beautiful trails in this forest.

Included on the map are all parking locations, campsites and all trail markers. The user can switch between topographic and satellite base maps.
