Lamar River Trail

This is a long 33-mile (53-km) there-and-back trail that follows the Lamar River all the way to Cold Creek. The trail stays on the east side of the river through the Lamar Valley and offers chances to see many of the park's large mammal species. CAUTION: Grizzly bears frequent this area.

Specimen Ridge Trail

This is a strenuous 17.7-mile (28.5-km) one-way hike that ascends over 3,300 feet (1000 m) up Amethyst Mountain before descending almost the same amount of elevation on the way to the Soda Butte / Lamar River Trailhead. Fording the Lamar River is required to reach the Soda Butte / Lamar River Trailhead, so use caution about crossing the river. Check the Backcountry Situation Report or at a backcountry office before taking the hike to make sure the river is crossable. This hike provides excellent vistas of the surrounding region.

Cache Creek Trail

Miller Creek Trail

A remote 7.4-mile (12-km) there-and-back trail that links several eastern boundary trails to the Lamar River Valley. Several backcountry campsites are along this trail.

What to do...

If You Encounter a Bear: Stay calm, do not run. Quietly detour or back away; stop if this seems to agitate the bear. Stay at least 100 yards (91 m) from bears. Do NOT feed bears or other animals.

If a Bear Charges You: Stand still, do not run. Stand your ground and use your bear spray. Spray when the bear is 60 feet (18 m) away or closer. If a bear charges, it may be a bluff charge.

If a Bear Makes Contact: Drop to the ground; play dead. Lie face down and clasp your hands over the back of your neck; stay still and silent. Wait several minutes after the bear leaves before getting up and leaving the area.
