DRIVING DIRECTIONS: The endpoint is variously called the Tunnel View Trailhead, the Pohono Trailhead, and the Wawona Tunnel Trailhead. It is located at Discovery View (aka Tunnel View), at the east end of Wawona Tunnel. This is on the Wawona Road (CA 41), 1.5 miles west of where CA 41 merges with Southside Drive in Yosemite Valley—or 7.75 miles north of the Chinquapin junction where the Glacier Point Road begins. The trailhead is on the south side of the road at the back of the smaller, subsidiary parking lot.
