There is a "Long Loop" and "Short Loop". The short loop is beginner/intermediate and the long loop is intermediate to expert areas. This trail is still under some construction as of 10/1/14 and has many sandy areas to be boardwalked in the future.
Across from Happy Chef Restaurant on the North edge of Mankato, right off Hwy 169. Park in lower gravel lot to the right after going around the large Kiwanis sign.
