The main trail follows a small river, up to the top. However, there are a lot of cutoff trails, and it's hard to get them all in on one day. Downhill is kind of rocky, so it's a bit tiring. Have fun!
Go west on W Deer Creek Canyon Rd, which intersects Wadsworth just south of C-470 by Chatfield. Travel 4 miles to Grizzly Dr and turn left. Parking lot is on the right about 1/2 mile up this steep road.
