Mountain Biking Dunning's Spring

****   Add a review
#30 of 96 mountain bike trails in Iowa
#3,940 in the world

No matter where you start, be prepared to climb. Rocks, roots, and hills.
Width of the trail varies from 12 inches and smaller. These trails have every
type of climb you want. Short, steep climbs; long, gradual climbs; long,
steep climbs. The only flat-ish trail is Captain's at the top of the trail but it
has plenty of log piles to make it enjoyable.
Recommended route: The Luge to Backside to Ice Cave/Dunning Springs to
Wold's Peak to Boa to Captain's to Mother's Day (hit Upper, Middle, and
Lower). You will finish near the top of the hill. Take Boa or Backside/one of
it's off-shoots to get down. Total length is around 5-6 miles.

Getting there
From downtown in Decorah take College Drive to Quarry Street/Ice Cave
Road. There are two main parking lots for this section. The first is on the
right, directly across the entrance to Dunning's Springs. The second parking
lot is about 1 mile further down the road, at the four-way stop. The River
trailhead is directly east of the first parking lot, all other trailheads are on
the north side of Quarry Street/Ice Cave Road. The River trail is a great
warm up or just ride on the road towards the four-way stop. Be sure to pick
up a map at the bike store on College Drive (Decorah Bicycles)
