Kings Creek Loop from Warner Valley

This is a demanding loop from Warner Valley to Flatiron Ridge, Kings Creek Falls and Bench Lake. The route map gives 10.5 miles and about 1,950 feet of climbing; a line traced along mapped paths measures closer to 9.3 miles, so treat the distance as approximate and plan for the longer full-day outing. Budget roughly 7–9 hours for steep grades, rough footing and stops.

A sustained climb reaches a long, waterless ridge before the creek and waterfall section. Carry the water you need before leaving the valley. Kings Creek is crossed near mile 3.7; the crossing can be difficult in high water, and descriptions disagree about whether a bridge is there. Do not count on a bridge. The Falls-side tread is steep and sun-exposed, with fire-damaged forest and standing dead trees nearby. Pets are prohibited on park hiking trails; service animals are exempt.

Start at the public parking area west of Warner Valley Campground, not inside the campground. Switchbacks climb toward Flatiron Ridge, whose open, dry stretch is the route’s main sustained effort. The loop reaches roughly 7,000 feet before dropping toward Kings Creek.

The crossing is followed by creekside trail and cascades on the way to Kings Creek Falls. Expect steep, rocky footing around the waterfall corridor and sun on much of the route. On the return, the trail drops through open forest, which can feel hot. For a shorter waterfall outing, the separate roadside hike to Kings Creek Falls is listed at 2.8 miles round trip; it is not this Warner Valley loop.

The circuit continues by Bench Lake before bending back toward Warner Valley. The lake can shrink or dry late in the season, so do not count on it as a water source. Meadows and streams give way to a long return through open forest.

Ice-age glaciers flowing from the Lassen Peak area shaped Kings Creek Meadows, Flatiron Ridge and Warner Valley. The route’s climb from valley to ridge and back through creek country makes that glacial landscape easy to read as you hike.
