Map of General Route:
Castle Peak is popular due to easy access from Hwy 80, high elevation start, and mellow terrain. Get a CA Sno-Park permit at our shop ($5/day or $25/season). You’ll find the parking area adjacent to the Boreal Ski Area Parking Lot, on the south side of Hwy 80. Take the Boreal Exit from Hwy 80. Then walk under the freeway and up a short, steep dead end paved road. Skin through the trees straight towards the peak and aim for the right shoulder. You don’t actually get to the summit. You are approaching the peak on the low angle south side. If you cross over the ridge, you’ll find a small but glorious north bowl with a few runs of about 800′. There are avalanches back here due to high winds and storm snow accumulation. You will also be close to snowmobilers. There is a nice side tour out to the Frog Lake Cliffs if you are looking for some spice.
If you are aiming for the small west slope and Peter Grubb Hut, which is maintained by the Sierra Club, don’t climb the south slopes. You will want to stay on the snow covered dirt road that is basically the continuation of the paved road. It heads west, right from the end of the pavement, and crosses over a the toe of Castle Peak’s South Ridge. Take off the skins after passing over the ridge down low in the trees, and drop just about 100′ of vert and look for the hut at the edge of the meadow. The hut is not far from the car really, maybe an hour skin. Book your stay, as the 3 local Sierra Club Huts are usually booked through the winter.
