Technical singletrack in native upland burr oak forest. Many intersecting trails of varying difficulty with optional "trail features" alongside main trails. This is a relatively small (80 acre) parcel of land... the organization of the interconnecting trails is continuously being improved by the local mt. bike club (LAMBA).
Copy-paste / type the address below into any map web site, there is a gravel parking area adjacent to an old softball field, here you will find a kiosk with information about the park and mtb club that stewards the area. To the left of the kiosk are entries to the trails... 37th Ave SW & 21st St SW, Cedar Rapids, IA 52405
