Arnot Creek Trail

Arnot Creek Trail is a long-distance hiking route in the Carson-Iceberg Wilderness on the Stanislaus National Forest side of the Sierra Nevada. The route runs along Arnot Creek and threads through a tree-burned valley bounded by granite bluffs.

The trail character is rugged and often exposed, with rocky, uneven footing and long stretches where you’ll be out in the open. Expect creek-focused navigation around the Arnot Creek corridor and plan on spending time on a slow, careful pace.

A common way to cover it is as a loop from Highland Lakes toward Arnot Creek, then back via the Highland Creek connection—about 20.2 miles with roughly 3,900+ feet of elevation gain for the full loop. It’s also commonly described as an out-and-back option toward Arnot Creek and the surrounding granite country.

Summer typically runs June through October, with winter access often limited by seasonal closures on the roads that serve the trailheads. Overnight travel in the Carson-Iceberg Wilderness requires a wilderness permit.

For the Highland Lakes access pattern, the route is associated with the Gardner Meadow Trailhead area at Highland Lakes; the Arnot Creek option is the Arnot Creek Trail turn in that trail network. Day use/overnight requirements can differ by access point, so confirm at the trailhead before you go.

Given the exposure and high-altitude conditions, plan for layers and sun protection, and carry enough water for the segments you’ll cover. The trail is described as challenging/strenuous, and the typical full loop timing is in the 10–11 hour range for many backpackers.
