The first mile is fairly gentle through patches of forest. The path then climbs gradually across the open Ruth Creek valley, with the white dome of Ruth Mountain appearing after about a mile and views toward Mount Sefrit and Nooksack Ridge. The creek stays below the route, and small waterfalls cross the trail. Short shady glades break up the open stretch, though biting flies can be a nuisance where the lower vegetation is dense.
Around mile three the grade picks up. Switchbacks climb toward Hannegan Camp and then through subalpine forest to the pass. About half a mile below the pass, a signed right-hand branch leads to camp; stay on the main trail to reach the pass.
