Overview
Lookingglass Creek flows north out of the Blue Mountains plateau to join the Grande Ronde River near La Grande, and its canyon offers a quieter alternative to the better-known river trails in Umatilla National Forest. The 6-mile out-and-back follows the creek through mixed conifer forest where western larch, ponderosa pine, and grand fir grow side by side, a forest composition that looks ordinary in summer but turns spectacular in October when the larch needles go gold.
The trail is straightforward with steady elevation gain. It sees light enough traffic that wildlife encounters are common. The canyon character becomes more interesting in the upper miles where old larch trees begin to dominate.
No permit is required. No facilities at the trailhead.
The Route
Miles 0 to 2: Creek corridor. The trail begins near the creek and stays in the narrow bottomland for the first two miles, crossing the creek twice on footlogs. Ponderosa pine dominates, with Douglas fir and grand fir appearing on the north-facing slopes. The creek is clear and cold, supporting trout visible in shallow pools.
Miles 2 to 3: Old larch grove. Around mile 2.5, western larch appears and increases in dominance on the upper slopes. In October this section is the visual highlight of the hike. The larch grove extends for about a half-mile before the trail reaches a broad flat near a forest road crossing at mile 3, which is the natural turnaround for day hikers.
When to Hike
May and June offer high water and fresh green growth. The larch leaves out in May, an underrated season for the tree. Crossings are more significant in May; wait for June if possible.
July through September are the driest months. The trail is fully accessible and comfortable. Wildlife is most active in early morning.
October is the standout month for this trail. Western larch turns brilliant gold from mid- to late October, peaking about the same time as elk bugling season. The combination makes an October morning on this trail particularly rewarding.
What to Bring
Many hikers carry 1.5 liters of water for this route. The creek is available throughout but requires treatment. Layered clothing is worth carrying; canyon temperatures can differ 10 to 15 degrees from the plateau above.
Trailhead Access
From La Grande, take OR-203 south, then forest roads west to FR-63. The trailhead is about 15 miles from La Grande. Paved road most of the way; the final 3 miles on gravel are suitable for standard vehicles.
