Lamar River Trail to Cache Creek

Overview

This is the classic Lamar Valley walk: big skies, rolling sage, and a mellow path to a shady creek. It’s roughly 7 miles total (out-and-back) from the Soda Butte/Lamar River Trailhead to Cache Creek, with about 300 feet of total gain. The grade is friendly, but the route is fully exposed—think sun, wind, and whatever the wildlife is doing that day. If you want an approachable Yellowstone day hike with a real shot at bison, pronghorn, and maybe wolves in the distance, this one delivers.

Route Snapshot

From the trailhead, you cross a bridge over Soda Butte Creek and climb gently above the valley. At about 1.4 miles, stay left to remain on the Lamar River Trail. The path undulates through open sagebrush and bunchgrass, threading a low pass before dropping toward the Cache Creek junction. Continue a short bit farther to reach Cache Creek—your natural turnaround for a day hike. You won’t need to ford the Lamar River to get here; continuing beyond Cache Creek typically requires a crossing and stronger backcountry skills.

Scenery and Wildlife

Expect sweeping views of the Lamar Valley with long sightlines to surrounding peaks and meadows dotted with seasonal wildflowers. Wildlife watching is a highlight—bison are common along the flats, pronghorn roam the open country, and this is prime territory to scan for elk, bighorn sheep, and the valley’s famous wolves. Carry binoculars, give animals a wide berth, and treat this as their home—you’re the guest.

Know Before You Go

• Exposure is real: the trail is open, sunny, and can be windy. Bring sun protection and more water than you think you’ll need.
• Bison frequently use or block the trail; you may need to wait or take a broad detour. Maintain at least 25 yards from most wildlife and 100 yards from bears and wolves. Carry bear spray and hike in a group if possible.
• Afternoon thunderstorms and lightning are a risk in summer; if storms build, move to lower ground and avoid ridgelines and lone trees.
• Park waters are swift and cold. Don’t plan to swim, and don’t attempt any crossing that looks unsafe. You can reach Cache Creek without fording.
• No pets on this trail. If you plan to fish, a park fishing permit is required.

Best Times to Hike

Late spring through early fall is the typical window. Summer brings heat and wind; aim for early or late in the day for cooler temps, softer light, better wildlife viewing, and easier parking. September often offers comfortable weather and fewer bugs. Expect delays whenever wildlife is active.

Who Will Love It (and Who Won’t)

If you want a half‑day sampler of Yellowstone’s wild, open country with standout wildlife potential and minimal elevation gain, this is a great pick. If you’re chasing rugged terrain or waterfalls, or you dislike sun-baked, exposed trails, you’ll likely find it underwhelming. For a bigger challenge, the area connects to longer backcountry routes—but day hikers are wise to make Cache Creek the turnaround.
