Mount Lindsey: The Blanca Massif's eastern outlier
Mount Lindsey is the eastern peak of the Blanca Massif — accessed from a separate trailhead than Blanca, Ellingwood, and Little Bear. The standard route includes a popular Class 3 alternate and an open-access challenge.
Mount Lindsey is the eastern outlier of the Blanca Massif — separated from Blanca, Ellingwood, and Little Bear by a different drainage and a different trailhead. The peak is climbed from the east via the Lily Lake trailhead, not from the Lake Como road that serves the rest of the massif.

How Mount Lindsey got its name
Named for Malcolm Lindsey, a Denver attorney and outdoor enthusiast who advocated for the peak's recognition in the 1950s. The peak previously appeared as "Old Baldy" on early-twentieth-century maps. The Lindsey naming was approved by the U.S. Board on Geographic Names in 1953.
The standard route
The standard Northwest Ridge route ascends from the Lily Lake trailhead off CR-559 east of Gardner. The trail climbs through aspens to the upper basin and ascends the northwest ridge on a Class 2 line, with one short Class 3 step. About 8.5 miles round-trip with 3,500 feet of gain.
Other ways up
The Direct Ridge (Northeast Ridge) is a more sustained Class 3 alternative — favored by climbers wanting cleaner movement and less loose talus. Adds technical interest without significantly changing distance.
When to climb
The Colorado fourteener climbing season is short. The standard window runs from late June through mid-September — after the snow has melted off the trail and before the first serious autumn storm. Outside that window, you're committing to a winter ascent: snow travel, avalanche assessment, post-holing through drifts, and route-finding without a visible trail.
Inside the window, the rule that has saved more Colorado lives than any other is be off the summit by noon. Afternoon convective storms build over the high peaks almost daily in July and August. Lightning is the leading weather killer in the Rockies. Plan for a pre-dawn start — most experienced climbers leave the trailhead between 4:00 and 5:30 AM.
Where it sits
What climbers wish they'd known
Trailhead access has changed. The Lily Lake trailhead has had access disputes with private-land easements. Check current Forest Service guidance before relying on the standard approach.
