Get an early start to squeeze this 13.9-mile loop into one day, or savor this super-scenic trip over the course of a weekend. From the overflow parking area in Benchmark, follow Benchmark Creek Trail to the northeast. The trail parallels and crisscrosses its namesake creek—and several tributaries—for the first 3.7 miles. (Tip: Bring an extra pair of socks.) Near mile 4, the path crests an unnamed summit, then climbs to the southeast before dropping down to Renshaw Lake, a quiet mountain tarn rimmed by conifers and a steep scree field. Set up camp beneath the trees, or continue the hike, following Renshaw Creek past wildflowers and grassy meadows. After 8.4 miles, turn right at the T-junction for the return trip, paralleling Fairview Creek. The hike finishes off with an easy, 1.6-mile road walk back to the trailhead.
