Lamar Valley is one of the most spectacular parts of Yellowstone National Park, and well-known habitat for all the park's wildlife. There are many backcountry sites along the Lamar River, well spaced for seclusion. Be sure to have a permit. This route makes an out and back of about 12 miles to the southernmost backcountry campsite on Lamar River Trail, but shorter and longer variations can be made with other camps.

All overnight trips require a backcountry permit from Yellowstone National Park. Permits are specific to designated backcountry campsites, and must be reserved in advance. See the national park website or Recreation.gov for more information and to make reservations.

At about 3.7 miles from the TH, you reach the Cache Creek and the first two backcountry sites. Plan your trip for the right time of year so you can cross the river safely. Typically after the 4th of July will give you the best odds for water levels to be low, but consult with the park rangers to be sure.

Once you cross the Cache Creek, the trail begins to climb. From here you'll go up and down following the Lamar River. The views are spectacular of the river below you! Along the way will be several more water crossings, and you'll be taking your boots off.

Bison, wolves, grizzly bears, elk, and mule deer frequent the area. Be sure to practice wildlife safety and proper food storage.
