Cascade Pass and Sahale Arm Trail

Route Description for Cascade Pass and Sahale Arm Trail

Cascade Pass is sublime. Meadows, valleys, glaciers, mountains—it’s all here. With dreamy scenery, wildlife, and a sense of solitude even when shared with others, Cascade Pass is a must-do hike. Go a little further, taking Sahale Arm Trail to the summit of Sahale Mountain. This gives you a wonderful view over the pass, especially in autumn when the colors turn.

The road into the hike is pleasant in its own right. The unpaved portion of Cascade River Road is lined with huge old-growth trees and the parking lot is in the shadow of a huge peak. It’s already sure to be a good day!

The hike begins from the trailhead parking, and it begins with a bang. The first nearly 4.8 km are consistent switchbacks before the path finally evens out to a one-mile traverse that’s more level in nature. The trees will gradually thin out as you get closer to the pass. Hike over a couple of rockfields and make a couple more turns before arriving in Cascade Pass.

Admire the view over the ridge of Johannesburg Mountain, Magic Mountain, Mixup Peak, and Cache Glacier. Behind you, El Dorado Peak dominates the view. Look for marmots and pika or even larger characters, including bears. They don’t wander into the pass too often, but they often eat berries on Sahale Arm.

From the pass, it’s time to head up Sahale. Take the trail heading north (left), switchbacking up a steep incline. This area tends to be filled with marmots, so watch for fuzzy faces if you stop to catch your breath.

About three-quarters of a mile from the pass, the trail climbs over a small slope, giving you a direct view of Sahale Mountain and its glacier. Go left on the trail, enjoying a stretch of flat trail before turning right towards the mountain. You’ll be back on a steep trail here.

About a half of a mile further, the path flattens out again. Before long, you’ll be heading back uphill, eventually over loose scree. The trail doesn’t relent until you arrive at the glacier camp. The views from here are too good for words, extending beyond Cascade Pass to mounts Formidable, Spider, Buckner, Storm King, and Goode, the tallest mountain in the park.

You won’t want to leave, but when it’s time, retrace your steps back to the trailhead.
