This hike combines great views over Sun Valley with a piece of its history––the Ruud Mountain chairlift, one of the world’s oldest according to [Visit Sun Valley](https://www.visitsunvalley.com/summer/hiking-in-sun-valley-idaho-a-summer-guide/).
You’ll pass the top of it near the end of this loop, which is a rewarding workout but very steep in places.
Really the loop is good in either direction, but on a hot day you’ll want to start by heading up the canyon instead of tackling Ruud Mountain first.
The canyon is partially forested and shaded, while the steep switchbacks on Ruud Mountain have no shade. Starting on Proctor Mountain Loop, going up the canyon, the trail is uphill and fairly steep the whole time, taking a few switchbacks in and out of the forest to gain a ridgeline.
From there, you’ll traverse beneath the summit of Proctor Mountain, through sagebrush meadows with wide-open views over Sun Valley toward Bald Mountain. A steep downhill and a gentler uphill gets you on the ridgeline of Ruud Mountain, where views continue to be spectacular.
That’s where you’ll come upon the chairlift, now defunct but enduring as a relic to Sun Valley’s rich history.
From there the trail continues very steeply downhill to return to the road.
Parking is at the edge of the neighborhood along Fairway Road.
Be sure to respect private property and park only where allowed.
