Silliman Pass South Trail

Overview

Starting from Lodgepole’s Twin Lakes Trailhead (signed as Silliman Pass South), this corridor is a sustained climb through forest toward high country lakes and granite. The lower signed segment covers about 4.9 miles one way with roughly 1,900 feet of gain, starting near 6,800 feet and topping out around 8,400 feet before the route transitions toward use trails and off‑trail options. Expect a steady grade with a few short, steeper pitches.

What You’ll See

Early on, the forest opens to glimpses of glacier‑carved terrain and, if you branch that way, the Silliman Lake basin—a worthy detour for a quick overnight or sunset stop. Higher up, the country trends toward slabs, meadows, and tarns above treeline with long views from divides. If you continue beyond maintained tread, features like Silliman Saddle, Tableland, and the Kings–Kaweah Divide deliver big, airy walking when conditions allow.

Route Options

• Lower sampler: Hike the lower 4.9 miles (one way) to get a solid workout and a taste of the scenery, then return. This guide’s mileage refers to this lower, signed segment only (one way).
• Twin Lakes outing: Use the Silliman Pass South corridor for a classic day/overnight to Twin Lakes (a medium‑effort loop).
• Big backcountry linkups: Strong parties extend this approach into multi‑day loops over Silliman Pass, Deadman Canyon, and Elizabeth Pass (very strenuous, with steep, sometimes tricky sections). Advanced hikers also use it to launch high‑route, mostly off‑trail traverses toward Silliman Lake, Silliman Saddle, Horn Col, and Copper Mine Pass into Cloud Canyon. Navigation skills are essential on these variations.

Difficulty and Conditions

On maintained tread the hike is a straightforward but sustained climb. Beyond the first couple of miles, sections may shift to use trails and cross‑country travel—expect route‑finding, slab walking, and occasional hand‑use scrambling near steeper passes. Snow can linger into mid‑summer on higher passes (notably around Elizabeth Pass on longer loops), and wind exposure above treeline is common. Marshy meadows may appear in places like Cloud Canyon later in the season.

Best Time to Hike

Late June through September is typical, but your objective matters. The lower segment and lake detours come into shape earlier; high passes and off‑trail traverses are safest later in summer once snow recedes. Start early for cooler temps and calmer winds; afternoon light is excellent around Silliman Lake and the high tarns. Summer weekends around Lodgepole are busy—weekday starts and using the park shuttle when running can ease parking stress.

Tips

• If you’re overnighting, secure the required wilderness permit and plan camps conservatively—there are no designated “backpacker camps” on this corridor.
• Bear‑proof your food. Lodgepole has bear boxes for anything you leave in your vehicle, and a canister is the simplest solution once you’re hiking.
• Treat all water. Creeks and lakes are common in season, but don’t rely on any single source.
• For off‑trail aims like Mount Silliman or Copper Mine Pass, bring maps and be honest about your navigation comfort. When in doubt, stick to the maintained out‑and‑back or the Twin Lakes outing.
