Trail guide
Cache Creek Trail is a 37.6-mile (60.5-km) out-and-back from Soda Butte / Lamar River Trailhead (3K1). It follows the shared trail corridor through Lamar Valley, then turns up Cache Creek into the Absaroka Mountains toward Yellowstone’s northeast boundary. It is long and strenuous; budget about 18 hours of walking, plus time for stops. At this distance and remoteness, plan it as a backcountry trip rather than a casual valley walk.
The route begins on shared marked trails from the large trailhead, then turns into the Cache Creek drainage and continues upstream. The creek valley opens into grassland beneath wooded slopes before the trail climbs farther into the mountains. Keep the established route at junctions: a field account describes multiple bison trails in the drainage that can be easy to confuse with the hiking line.
A recent multi-day trip through this drainage recorded antelope, bison, moose, elk, deer, bighorn sheep, and mountain goats. Those are possible sightings, not a promise; give wildlife room. Yellowstone’s waters can be swift and cold, and crossings are hazardous. Snowmelt can keep streams high into summer.
Pets are not allowed on Yellowstone hiking trails or in the backcountry. Every overnight stay requires a permit for specified campsites and dates; use designated campsites and follow the park’s food-storage rules.
