For the first mile the trail makes an U-shaped bend as it follows the Gold Camp Road. Exit the road after you pass a collapsed tunnel. Trail #624 then continues along a creek through the Buffalo Canyon. After about 1.7 miles you will reach the sign pointing to the base of the St Marys Falls. After enjoying the view of the falls you can continue up through several switchbacks to the top of the falls or continue to Mount Rosa.
Length: 6.2 miles roundtrip
Directions: Coming south on I-25 take exit 140 to access Cheyenne Canyon. Drive all the way through past Helen Hunt falls until you reach parking lot at intersection with Gold Camp Road
