Tunnel Drive is a fascinating road on the outskirts of Canon City. It leads to a trail that ascends cliffs via an old railroad grade. Vehicles with handicapped stickers can drive up the first steep section of the trail, but others have to walk it. The rocky areas along the trail are famous for Rufous-crowned Sparrows, which are not numerous here at the northern extreme of their range, but can be found year-round with a little luck. More common birds include Canyon and Rock Wrens and White-throated Swift. Look for bighorn sheep and deer farther down the canyon.

Directions: To reach Tunnel Drive, follow US-50 through the center of Canon City, and as the road bends to the north by the large prison, take a left onto Tunnel Drive. Follow the road to a small parking area at the base of the cliffs, along the river.
