Four miles of the Continental Divide Trail lead to a locals' favorite downhill on the Switchback Ridge Trail. The CDT portion doesn't climb very much, but it is strewn with very challenging rock gardens. The downhill is relatively buff until the last few hundred yards.

Exit Highway 12 at the Cromwell-Dixon Campground, and drive up the hill to the Continental Divide overlook. The trail starts at the stairs. There is a gate shortly after entering the forest; be sure to close it behind you. As the CDT rises into an open meadow, stay left towards the trees to start the downhill.

During the summer months, the Bike Helena Trail Rider runs shuttles from the City of Helena's Tenmile Water Treatment Plant up to the CDT overlook. This is a great way to do this ride, as at the end you only need to roll back down Rimini Road to your vehicle. The schedule is available at the Bike Helena website: http://www.bikehelena.com/index.php/trail-rider/
