Turquoise lakes nestled in dramatic glacial cirques, wildflower-filled meadows ringed by craggy peaks and a pass with see-forever views puts Blue Lakes atop my "to do list" on every trip to southwest Colorado.
The hike, one of the few in the Mount Sneffels Wilderness, culminates at spectacular Blue Lakes Pass (13,000-ft.) located on a steep ridge extending south from Mt. Sneffels (14,150-ft). Along the way the trail visits three scenic lakes cradled in beautiful glacial basin set amid rugged peaks soaring over 13,000-ft.
For an easy day Lower Blue Lake, lying in a pretty cirque dominated by Dallas Peak, makes a worthy destination. Still have energy to burn? Continue on the steep trail leading to the upper lakes set beneath the western flanks of Mt. Sneffels in wildflower filled meadows ringed by jagged ridges. Beyond the lakes a demanding trail ascends 1,250-ft. in 1.4 miles to the panoramic viewpoint at the pass.
Trailhead to Lower Blue Lakes
Distance from Trailhead: 6.3 miles (round trip)
Ending/Highest Elevation: 10,940-ft.
Elevation Gain: 1,590-ft.
The Blue Lakes trail, starting at the north end of the trailhead parking lot (see driving directions below), passes through a gate and soon reaches a signed “Y” intersection. Here the trail to Blue Lakes branches right and ascends on moderate grades through a forest of Engelmann spruce and pines along the right (west) of East Fork Dallas Creek. (The trail to the left leads to Blaine Basin.) Occasional openings in the trees provide tantalizing views of surrounding peaks.
After an hour of climbing intermittent meadows provide vistas of the rugged peaks lining the lower basin. Soon after passing an avalanche chute on the east side of Wolcott Mountain the grade moderates. You'll know when you are less than 1/3 of a mile from the lower lake when you see a waterfall tumbling down a rocky cleft on your left (southeast).
Past the waterfall the trail climbs on moderately steep grades to a signed junction with a short spur trail leading straight ahead (south) to Lower Blue Lake. The trail branching to the left (east) continues to the upper lakes. Acclimated hikers will reach this point in about 1 1/2 hours (3.2 miles, 1,500-ft. elevation gain).
Pretty Lower Blue Lake (10,940-ft.) lies nestled in a scenic bowl beneath a cirque of jagged peaks dominated by Dallas Peak (13,809-ft.) to the southwest. Mount Sneffels (14,156-ft.) rises to the east. Steep scree slopes spill down the cirque's rugged walls to the southern and western shoreline of the lake. Nice campsites, sheltered by trees, are located on the lake’s north shore, with addition sites to the east across the creek.
Lower Blue Lakes to Upper Blue Lakes
Distance from Trailhead: 8.2 miles (round trip)
Ending/Highest Elevation: 11,750-ft.
Elevation Gain: 2,400-ft.
To reach the upper lakes return to the junction and turn east. Drop down to the East Fork of Dallas Creek and find a place to cross. Several large logs will help keep your feet dry. The continuation of the trail is on the left (north) side of the creek draining the upper lakes. Finding the trail on the other side of the creek can be little confusing due to erosion and use trails leading to campsites.
The path now climbs steeply up the headwall of the lower basin, en route crossing back to the west side of the creek. As you climb trees give way to alpine tundra filled with wildflowers in mid-July to early August. At the top of the cliff the trail reaches a fantastic viewpoint showcasing the lower lake basin.
Beyond the viewpoint the climb moderates as the trail passes to the west and above middle Blue Lake, reaching Upper Blue Lake after 0.9 miles and a 700-ft. elevation gain. (Total hiking distance: 4.1 miles / 2,350-ft. of elevation gain.)
The upper lake is set amid meadows dotted with wildflowers. A scenic ridge with steep scree slopes tinted bronze, rust and gold extends from Dallas Peak to Gilpin Peak (13,694-ft.), forming the southern wall of the upper basin. The ridge between Gilpin Peak and Mt Sneffels creates the eastern wall.
While the upper basin is a great destination and the perfect place to relax and take in the scenery, hikers with the time (and good weather) will want to climb to Blue Lakes Pass (13,000-ft), which lies 1,250-ft. above the upper Lake on the ridge extending between Mt. Sneffels and Gilpin Peak.
Upper Lakes to Blue Lakes Pass
Distance from Trailhead: 11.0 miles (round trip)
Ending/Highest Elevation: 13,000-ft.
Elevation Gain: 3,650-ft.
To reach the pass follow the well-defined trail around the left (east) side of Upper Blue Lake to a series of long, steep switchbacks. As you ascend fields of wildflowers give way to dirt and talus. Footing is generally good except for a few eroded sections with some exposure.
Take occasional breaks from the climb to admire the wonderful views of the jagged ridge towering above the sapphire blue lakes nestled in the upper basin. Reach the top of the pass in 1.4 miles (total distance: 5.5 miles with 3,650-ft. of elevation gain from the trailhead).
The pass offers splendid views to the north of the peaks and ridges defining the Blue Lakes basin. To the south is Yankee Boy Basin dominated by Gilpin Peak (13,694-ft.), Potosi (13,786-ft.) and Teakettle Mountain (13,819-ft.). In the distance a series of peaks and ridges form the northern wall of Yankee Boy Basin.
On the northeast side of the pass a faint trail marks the start of a Class 3 route climbing Mt. Sneffel’s southwest ridge. (see: Summit Post Mt. Sneffels for more information on climbing Mt. Sneffels.) This route should only be used by parties with prior climbing experience. Most people climb Mt. Sneffles (14,156-ft.) from a well-defined Class 2 route that begins in Yankee Boy basin.
Once you are done soaking in the scenery retrace your steps to the trailhead. Parties with a pre-positioned second vehicle can continue over the pass and down to a 4WD road in Yankee Boy Basin (1.4 miles).
Note: This is a popular trail that is best hiked on a weekday if you wish to encounter fewer people on the trail.
