Lundin Peak View and Red Mountain via Old Commonwealth Trail

Route Description for Lundin Peak View and Red Mountain via Old Commonwealth Trail

Old Commonwealth Trail is a great hike throughout the year, and it provides access to the thrilling ascents of Red Mountain and Lundin Peak, which involve a sky-high scrambling section. This is a good hike for those comfortable with exposure, heights, and intermediate scrambles. If that’s not your style, skipping Red Mountain might be best.

Begin at the PCT trailhead. The Old Commonwealth Trail split off left from the PCT very quickly so make sure you watch for the turn. Stay right through two junctions and cross the creek. This first mile or so is quite flat and relaxed, but also deep in thick brush and potentially overgrown.

When you cross Commonwealth Creek, look for a bridge to use to cross and then return to the trail. Head northwest, you’ll merge onto Commonwealth Basin Trail. A handful of stream crossings lead you up to where you’ll begin to climb a bit more aggressively, hiking through very narrow switchbacks.

Stay right at the junction around 1,480 m and begin your ascent of Red Mountain. It’s fairly short in terms of distance, but expect the last mile or so to take longer as you navigate the scramble. Some hikers report feeling uncomfortable and turning around before the summit, which is exactly what you do if you feel too far outside of your comfort zone on this section. Otherwise, after enjoying the summit, you’ll descend and then continue north on the trail.

Climb the ridge in front of you, going left towards Lundin Peak. Many hikers just enjoy the view for the false summit if the true summit seems too far, so it’s up to you whether you go the whole way or not. From where you are, turn around and retrace your steps to the trailhead.
