Wapehani Mountain Bike Park is a 1 mile loop trail located near Bloomington, Indiana that features a lake. The trail is rated as moderate and primarily used for mountain biking.
Me, my wife and 4 children enjoyed our time there (on foot). Lots of small loops and connectors for the children to explore. We had it all to ourselves on a Saturday.
Wapehani is a small area with many offshoots. It is fun to ride and encircles a small lake with a very large and old turtle. There are many trails with moderate climbs and some courses have obstacles to ride on or around.
