Navigation: From Jefferson, CO. head north-east on US Hwy 285 for 1.2 miles. Turn right onto Lost Park Road, County road 56, and go 10.8 miles. Turn right to stay on Lost Park Road and go 6.6 miles. Turn right onto Bonis Creek 4WD road.
Bonis Creek 4WD road starts in Lost Park just before the Lost Park Campground. After crossing the south fork of Lost Creek the road will climb up into the forest and come to an intersection. The right turn is a spur road, FR853.A, that climbs to the top of the ridge above Bonis Creek. The left continues following Bonis Creek.

The main road will continue as a two track along the creek before crossing and quickly climing to an intersection with the Wallace Gulch road, FR854, which takes you back to the Lost Creek valley. Continuing to the right, the Bonis Creek road will loop around the head of Bonis creek passing a large camp site. About a mile further you will come to the intersection with the Topaz Mountain road, FR446, to the left. The right goes to the other end of FR853.A.
