Fourth of July Pass
What to Expect
Safety Advisory
The upper mile is fully exposed with no tree cover — afternoon thunderstorms roll in fast over the Cascades in summer. If clouds are building by early afternoon, start heading down.
Black bears are active along the Thunder Creek corridor through September. Carry bear spray and know how to use it — this isn't a drill, encounters happen here every season.
Trail Details
Pro Tips
Start by 7:30 AM to claim parking at the Colonial Creek trailhead — it shares the lot with the popular Thunder Creek Trail and fills fast on summer weekends.
Snow lingers on the upper stretches well into July most years. Bring microspikes if you're hiking before mid-July, and check the Marblemount Ranger Station's trail conditions report the day before.
The best photo op is about a quarter-mile before the pass where the trail breaks out of the trees — you get Neve Glacier framed by subalpine firs with no scrambling required. Afternoon light hits the glacier face perfectly.
