Corral Pass is set in a beautiful alpine setting with several hiking trails within walking distance. The Rainier View Trail provides scenic overlooks while the Greenwater Lakes Trail accesses the Norse Peak Wilderness. Noble Knob Trail is nearby and open to mountain bikes. The steep, narrow winding FS road 1174 that accesses the campground is not recommended for trailers or RVs.
I loved this place. The drive up was rough, steep, and slick. I would never attempt with a trailer or even cab over camper. We took the tent and my Subaru Crosstrek up, took it slow and did just fine.
There were a lot of large downed trees being cut by the forest service scattered everywhere. Two loops of campsites, roughly 20 in all. Two very rustic pits and one typical vault toilet near the Rainier View Trail trailhead that departs from the parking lot at the beginning of the campground. No water, power, trash, tables, metal fire rings, or really people up here.
Total, almost creepy seclusion. We saw no animals either. A couple multi day trip backpackers came passing through.
Unfortunately, the large Norse Peak wildfire swept through in 2017. This road is permanently closed. I hear you can park and walk the roughly 6 miles up past the gate to the former campground. Not much left up there for camping. Maybe the Forest Service will reopen it someday? If so, it's worth the drive for the peace and quiet or to do what you do with a group and not be disturbed.
We camped off Mather memorial parkway for just a few hours during a Questival and found it to be quiet, easy to access and plenty of firewood. Loved sleeping by the creek!
