Vista Trail

The Vista Trail begins at the upper observation deck, which provides views of the White River basin to the north, and Mud Mountain Dam to the south. Descending 1/3rd of a mile down moderately steep switchbacks brings visitors to the lower observation deck, providing a closer view of the dam and it's operational areas.

The 2-mile Rim Trail follows the White River and provides views of ancient volcanic mudflows and other sedimentary deposits that formed the reservoir rim.  This is an easy hike with terrain that is gentle to slightly sloping and offers spectacular views of the White River canyon and neighboring mountains.

Hikers and mountain bikers can also join horse riders on the River Trail.  This 3.1-mile trail begins at the equestrian parking lot about two miles north of the day use area.  You can wander down through mature and transitional stands of forest on a trail that gradually opens into mudflats along the banks of the White River. You can enjoy unobstructed scenic views, abundant wildlife, and access to the White River.
