this is really good single track, great for the area. there is a small fee to ride there. the single track loops all over what the local people call there mountain. there are some really good short distance steep climps and some fast short down hill sections. if you ride in minnesota this is a must. well good luck and keep a good cadence!!
when you come into mankato in 169 south exit at riverfront srive and take a right onto river front then follow the sign to mountkato ski area. thwy will lead you out a windy highway minnesota state 66. this will lead you right to the hill. you will see the chair lifts.
