Sahale Mountain via Sahale Arm
A one way trail plus technical scramble takes you to the top of Sahale Mountain in North Cascades National Park. The 30-something switchbacks makes the trail easy on the knees to Cascade Pass. Continue into the alpine for impressive mountain views.
Drive to Marblemount and turn onto unpaved Cascade River Road for 23 miles. The road closes in the winter, so make sure you check the road closures for the park before you go. Drive to the end of the road and find parking in a large lot. Make sure to display your Northwest Forest Pass on the dash before hitting the trail.
Gradual switchbacks make the beginning of the hike to Cascade Pass feel like an easy jaunt. From Cascade Pass, the trail leaves the treeline and the trail becomes rocky.
Stop at Sahale Arm, where small backcountry campsites are a hot commodity and require a backcountry permit. From Sahale Arm, strap on those gaiters, and maybe crampons, to cross the Sahale Glacier to a boulder field.
Choose your own adventure through the boulders aiming towards the eastern ridge with Boston Peak coming into view as you gain elevation. Scramble to the top or consider roping-up with harnesses for a belay to ease the exposure nerves. From the summit, view the jaw-dropping glaciers of Boston Basin and jagged peaks, including Forbidden Peak and Eldorado Peak.
Slowly down-climb or rappel off the summit as Boston Basin disappears behind the ridgelines. Retrace your tracks from Sahale Arm.
After Cascade Pass the trail become rocky with high exposure with consequences to the top. Consider going to the Pass or Sahale Arm for a day trip that provides an introduction to the area.
