Alpine Lakes, Bristlecone, and Glacier Loop

This is a linked loop-and-spur hike of about 6 miles: follow the Alpine Lakes circuit to the Bristlecone junction, visit the grove, continue up Glacier Trail to the Rock Glacier, then retrace that branch and finish the lake loop. You get two small alpine lakes, a stand of old pines, and a high boulder-filled cirque in one demanding half-day. The saved trail line measures 5.96 miles. Published totals run from about 5.8 to 6.5 miles because accounts measure the connected segments differently, so treat 6 miles as an estimate. Allow about four hours, longer if you linger. The start is near 9,890 feet; the signed glacier endpoint is about 10,800 feet, with roughly 1,250 feet of cumulative climbing along this mapped route.

The elevation is part of the challenge: even the lake section begins higher than many visitors are used to, and the climb to the grove and cirque is steep and rocky. Carry water before driving up; there is no potable water along Wheeler Peak Scenic Drive, and the trailhead toilets have no running water. Afternoon thunderstorms are a recurring high-country hazard, so plan the climb with time to turn around before weather builds. Pets are not allowed on park trails. Parking at Bristlecone Trailhead is limited; use marked spaces and do not park along the road. When the scenic drive is seasonally closed, this saved itinerary no longer begins at a drive-up trailhead, so check the current access route and added distance before setting out.

From Bristlecone Trailhead, bear right at the early junction for Alpine Lakes rather than taking the Island Forest spur. The maintained path climbs through conifers, crosses a small creek, and uses a short boardwalk before opening toward Wheeler Peak and Doso Doyabi. Stella Lake arrives at roughly a mile, with a broad shore and a striking peak backdrop. It is exposed, so there is little shade beside the water. Continue through pine thickets to smaller Teresa Lake, around 1.8 miles from the start, then climb a short rocky rise to the Bristlecone fork. Teresa’s water level varies with precipitation and can be very low in a dry year.

Leave the lake circuit for Bristlecone Trail. The path climbs across a slope, crosses a rocky wash, and gets steeper on loose, rocky switchbacks. At the grove, take the short interpretive loop to see the twisted, weathered trunks up close; some bristlecone pines here are more than 3,000 years old. Return to the main path and follow the Glacier Trail signs. The grove is a destination in its own right, but it is not the end of the glacier route.

Beyond the grove, the trail rises above treeline through moraine and boulder fields toward the sign marking Rock Glacier at about 10,800 feet. This is a rock-and-ice mass slowly moving within a glacial cirque, not a wide white ice field. Snow patches can look like the glacier from below, so continue to the signed endpoint for the intended destination. The upper tread is rough and exposed; this section can feel much harder than the mileage suggests.

Retrace Glacier Trail to the Bristlecone junction, then take the remaining Alpine Lakes path to close the loop instead of walking the entire approach twice. At Stella Lake, the shore makes a good pause for a photograph: frame the water with Wheeler Peak and Doso Doyabi above the far slope. Water levels and seasonal color change the scene, but the open basin keeps the mountain view in the composition.
