Holly Lake Trail

The Holly Lake Trail is a strenuous 12.8-mile out-and-back from the String and Leigh Lakes Trailhead, climbing through Paintbrush Canyon to a high alpine lake at about 9,400 feet. Plan on a full day: the park estimates seven to nine hours and 2,840 feet of elevation gain. This is a good pick if you want a long climb with a clear destination; it is a lot of work for a quick lakeside stop.

Cross the bridge over String Lake’s outlet and follow the west shore toward Paintbrush Canyon. That is the approach represented by the 12.8-mile figure. The first few miles are comparatively gradual under dense lodgepole pine, with occasional glimpses of peaks through the trees. A different route around the north and east side of String Lake adds distance, so keep the shoreline approach in mind when comparing mileage.

The forest gives way to Lower Paintbrush Canyon, where a rocky ledge looks down toward Paintbrush Creek and the lower camping zone marks the change into open country. The south wall’s banded gneiss is worth a look as you climb. Farther up, the canyon narrows around the creek, then opens again across switchbacks. Expect exposed roots and rocks, bridge and creek crossings, and steep, narrow sections. As the trees thin, views spread back over Leigh Lake and Jackson Lake below.

At the upper junction, turn right onto the lake spur; continuing west leads farther up Paintbrush Canyon toward Paintbrush Divide. The final approach is about half a mile. It passes through high alpine trees and alongside a small creek before reaching Holly Lake. The lake sits in a rocky basin below Mount Woodring and The Jaw, with open boulders along the shore. It is a satisfying place to stop after the climb. Keep the shoreline and the enclosing rock walls in the frame if you want a photo that shows the setting, not only the water.

The distance is only part of the effort. The long ascent, rough footing, altitude and narrow sections make this a strenuous hike, even though the lower approach starts gently. The high-country season is short: the park recommends going after snowmelt in summer or before the first fall snow. Do not travel over snow here without prior experience and proper equipment.

The trailhead is at String and Leigh Lakes, beside the String Lake Picnic Area. Day hikes need no reservation or activity permit, but the park entrance fee applies. Pets are not allowed. Overnight backcountry camping requires a permit. No food service is identified at the trailhead or along the route, and the lot’s capacity and overflow are unclear.
