Barney Riley Access provides a challenging 11. 2-mile trail connecting Markleeville to the East Fork Carson River, featuring natural hot springs with user-built stone pools and riverside camping opportunities.

The rough, rocky terrain (rated moderate to difficult) requires high-clearance 4x4 vehicles and is best accessed during summer months; motorized vehicles cannot cross the river, but foot, raft, and canoe crossings are possible.

The trail offers scenic aspen groves and canyon views along the Carson River, making it a notable destination for off-road enthusiasts and river access seekers.
