01
Classic alpine day hike
Granite Lake via Swift Creek Trail
Swift Creek Trailhead West Of Trinity Center • Forest And River Canyon Hike To Alpine Lake • Classic Trinity Alps Sampler
A rewarding out-and-back that follows Swift Creek to a bowl of polished granite and a cold, clear mountain lake.
From the Swift Creek trailhead, the path climbs gently along the water before steepening toward the upper basin and Granite Lake. You get a little of everything: shaded riverside walking, big granite walls, and open views as you gain elevation. It’s a solid day for fit hikers and an excellent first taste of the higher Trinity Alps country.
02
Best short, steep payoff
Boulder Lakes Trail
Coffee Creek Road North Of Trinity Center • Short, Steep Climb To Granite Bowls • Best Bang-For-Your-Buck Views
A brisk climb lands you at a pair of compact alpine lakes tucked into bright granite cirques above Coffee Creek.
The Boulder Lakes trail wastes no time gaining elevation, switchbacking quickly out of the forest to more open slopes. In a few miles, you’re circling small lakes ringed by rock slabs and low ridges, with options to poke around for quieter shoreline nooks. It’s a favorite for strong hikers who want big scenery without committing to an all-day epic.
03
Iconic backpacking route
Stuart Fork to Emerald and Sapphire Lakes
Stuart Fork Trailhead South Of Trinity Center • Long River Valley Hike Into High Alpine Basins • Classic Multi-Day Adventure
A long, gradually climbing valley trail that builds to a dramatic pair of deep blue lakes beneath jagged peaks.
Starting near Trinity Lake, the Stuart Fork trail follows the river for miles, passing side creeks, big ponderosa pines, and occasional meadows. The grade is kind, but the distance adds up, making this ideal as a one- or two-night backpack to Emerald and Sapphire Lakes. Expect classic Trinity Alps drama at the head of the valley, with steep granite walls dropping straight to the shoreline.
04
Steep climb to open high country
Long Canyon Trail
Long Canyon Trailhead Off Highway 3 • Direct Ascent Through Forest To Subalpine Meadows • Best For Strong Day Hikers
A no-nonsense climb that trades shade and switchbacks for quick access to airy meadows and ridgeline views.
Long Canyon is straightforward and steep, gaining serious elevation in a relatively short distance as it pushes into the heart of the Trinity Alps. Once you break out of the thicker forest, views widen quickly and small stream-fed meadows dot the upper canyon. Ambitious day hikers can tag the high basin and start of the passes before turning around, while backpackers often use this as a gateway to deeper routes.
05
Signature high-country loop
Four Lakes Loop
Backcountry Above Long Canyon And Deer Creek Pass • High Alpine Backpacking Circuit • Premier Overnight Loop
A rugged circuit that strings together four alpine lakes along airy benches and passes high above the main valleys.
Most hikers reach the Four Lakes Loop via Long Canyon or nearby trail systems, then settle into a rolling high-country traverse that rarely dips far below tree line. The loop arcs past a series of lakes perched on shelves, each with slightly different aspects and views across the surrounding peaks. It’s demanding enough to feel remote but compact enough to savor over a long weekend, making it a standout Trinity Alps classic.
