Silliman Pass Trail

Start from the day-hiker lot beside the Lodgepole bus stop. Cross the Marble Fork Kaweah bridge, pass the Tokopah Valley Trail junction, and take the signed Twin Lakes Trailhead about 30 yards farther on. The route length begins at that signed trail, not at the lot. The early climb moves through open Jeffrey pine and incense cedar, then settles into fir forest. Silliman Creek is about 2.3 miles in and Cahoon Meadow about 2.7. A sustained climb reaches Cahoon Gap near mile 4.3, followed by a descent to Clover Creek and the junction around mile 5.1. From there, switchbacks climb beside East Fork Clover Creek. Look for the fractured-granite cascade near mile 5.8, Twin Lakes around mile 6.8, then the final forested climb to the pass at roughly mile 7.6 to 7.7. Expect uneven rocky tread and creek crossings.

The two lakes have different characters: the southern lake is larger, while the northern one is smaller and swampier. From the north lake shore, Twin Peaks rise above the water; include the rocky shoreline in a photo to show the scale of the peaks. The pass itself is mostly forested, so do not expect a wide-open panorama at the high point. For a more open view toward Mount Silliman and the Beville and Ranger Lakes area, continue about 0.7 mile down the north side. That optional detour adds roughly 1.4 miles round trip and you must climb back over the pass before returning to Lodgepole.

The climb passes from dry, open pine and cedar into red and white fir, then into upper-elevation lodgepole and western white pine. Cahoon Meadow interrupts the forest, and the creek cascade crosses fractured granite. The Sierra’s granitic bedrock formed deep underground as magma cooled; later glaciers carved the hanging valleys and lake basins visible above Lodgepole. The name Silliman honors Benjamin Silliman, a Yale chemistry professor who taught William Brewer. Brewer was among a party credited with the first ascent of Mount Silliman in 1864.

Snow can linger near the pass into early summer, and the best window depends on the year’s snowpack. Check current park conditions before you go, set a turnaround time, and allow enough daylight for the return. No food or water service is confirmed along the route, and creek flow changes seasonally. Overnight trips require a wilderness permit; dogs are not allowed on park trails. The trail starts near Lodgepole, where the bus stop and day-hiker parking are together, but the signed trailhead is across the bridge and a short walk beyond the Tokopah junction.
