These trails are a fun place to ride close to Bloomington-Normal. The network consists of a wide doubletrack backbone maintained by the McLean County Parks and a number of singletrack loops that shoot off of the county trail. Some people like to make a loop, riding the county trails out and the singletrack back or vice-versa. I sometimes ride out & back both on the singletrack. The singletrack is for the most part pretty flat but tight & twisty. The two new sections north of the dam add a little elevation, particularly the newest (and as of 10/25/03 unfinished) section northeast of the dam. Highlights of the park include a series of ravines in Section 5; a number of logpiles in sections 6, 4, 3, "Bovine Run", and the new-new trail; a fast downhill/slow climb (depending on which way you go) on the new-new trail, and a floating bridge on the county trail. Comlara Off-Road Biking Association (CORBA) builds and maintains the trails; see our website (linked on this page) for more information about the club, more detailed descriptions of each section, and a few pictures of us building and riding the trails.
Find Exit 8 on Interstate 39 (8 miles north of Normal).<br />Go west on the road that crosses the I-39 (Lake Bloomington Road / County Highway 8). In 2 or 3 miles you will cross the dam that holds back Evergreen Lake (about halfway to the dam you will see a wooden sign for the campground & visitor center; do not turn here, but continue on straight). A mile or so past the dam, there is a gravel parking lot on the left where the woods end and cornfield begins. This is probably the best place to begin -- there is a bulletin board with a large map, general info, and a few 8 1/2 x 11 copies of the trail map in a mailbox on the back of the display. If you prefer, you can park at either end of the dam or at the big log between the dam and the main parking lot; all of these have or will soon have a smaller display showing the trail map.
