The approach sets the outing’s scale
Sand Creek Lakes lie in the alpine watershed of Great Sand Dunes National Preserve, a long drive and high-elevation hike from the east side of the Sangre de Cristo Mountains. The approach begins from Highway 69 south of Westcliffe, turning west at the Music Pass and South Colony Lakes sign, then left at the T junction onto South Colony Road. A second Music Pass sign appears at the end of the ranch fence on the right. NPS
The road determines where the hike begins. Two-wheel-drive vehicles should park where Rainbow Trail crosses Music Pass Road; from there, the lower trailhead adds 2.5 miles each way. High-clearance four-wheel-drive vehicles may continue another 2.5 miles to Music Pass Trailhead at the road’s end. NPS
Climb to the basin
From Music Pass Trailhead, a steep 1 mile hike reaches the pass at treeline. The view opens onto Upper Sand Creek basin, turning the pass into a natural decision point: continue toward the lakes or take in the basin from above. The trail beyond leads into alpine terrain, with the lakes set below peaks above the basin. NPS
The lower lake is listed as an 8-mile round trip from Music Pass Trailhead, and Upper Sand Creek Lake as a 9-mile round trip. Both routes have 2000 feet of elevation gain. These figures begin at the upper trailhead; starting from the two-wheel-drive parking point adds the stated road-access extension to the hike. NPS
Choose the season and surface
The trail becomes steep and rocky beyond the vehicle-accessible Music Pass Trailhead and is unsuitable for wheelchairs. Snow may block the route from November into June. Although the preserve is open year round, the lakes are recommended for summer or fall unless hikers have snowshoes and avalanche gear; snowdrifts may remain through June in an average snow year. NPS
Mid-summer brings blooming flowers, green grass, and snowfields still visible on the mountainsides. Those conditions give the approach a changing alpine character, but the high elevation and round-trip distance make this a long-day outing. The park advises planning enough time for the drive, hike, lunch, photos, and exploration. NPS
An alpine destination with a choice
Visitors can make the lakes a day hike or backpack to marked campsites set back from the water. No reservations are needed to camp in the preserve. Pets are permitted in the preserve on leash at all times, with cleanup required. NPS
For a shorter commitment, the pass itself provides a view over Upper Sand Creek basin; reaching either lake extends the outing into the alpine watershed. Check conditions with a ranger before travel, since snow and the vehicle approach both shape whether the lakes are accessible. NPS
