    The Convict Lake trailhead is about seven miles south of Mammoth Lakes. The route follows Convict Lake's north shore into a rugged canyon. A hazardous stream crossing occurs within three miles; Mildred Lake is five miles one way and Dorothy Lake six miles one way. Trailhead and overflow parking directions are published, and overnight wilderness stays require a permit.

  1. Evidence stance: supports · Evidence details

    The official Forest Service Convict Lake hiking map depicts a continuous dotted hiking route around the lake. The retained south-shore trail reaches the road and cul-de-sac on the lake's east side; the mapped loop follows a road connection, returns to an east-side lakeshore trail, and then uses another road connection through the boat-ramp and trailhead-parking area to rejoin the retained north-shore trail. The map does not publish individual leg mileages or reusable line geometry for these three mixed-surface connections.

    The July 2026 USGS Transportation service returns the Convict Lake Road and Boat Launch road features plus a paved 0.34564349-mile CONVICT LAKE VIS trail. Their geometry matches the road-trail-road loop closure depicted by the official Forest Service hiking map. The south road feature intersects the paved trail endpoint within 0.4 meter; the north road and retained trail endpoints match within approximately 1.4 meters.

    The Forest Service guide directs drivers two miles west from US 395, then right toward the trailhead parking area. It identifies overflow parking at the south end of the resort. Its map depicts the trail leaving the parking area and continuing around the north shore on a paved-road approach. It does not publish parking capacity, restroom details, or potable-water service for the trailhead.
