The Monument Creek trail is a mostly-unmaintained trail through the Pasayten Wilderness that connects to the Hidden Lakes trail. The first four miles of trail are well maintained and wind through old growth forests and rock slopes along the river. Find the description of that hike in our Lost River entry.

The maintained trail stops after a bridge washout at Eureka Creek, but for confident hikers the trail continues on into the Pasayten for many more miles. The section of Monument Creek trail past the bridge washout should be attempted only by confident hikers with solid navigational skills, since the trail beyond this point has not been maintained for over 30 years, so is impassable for stock and extremely difficult for hikers.

This trail is part of WTA's Lost Trails Campaign. Learn more about how we're saving lost trails across the state here.
