North Creek Canyon is entirely located within the Mount Nebo Wilderness. Wilderness rules apply (nothing mechanized or motorized allowed, including power drills).
This canyon is home of the ice climb, Frozen Assets. You can see it looking East, high on the steep North facing limestone wall while driving South on Interstate 15 as you approach Mt. Nebo.
Getting There
Take the Mona exit just before Mt. Nebo. Go west to Mona. Turn right and follow a frontage road going north. Turn east on a dirt road leading past a quarry. Follow a the road to the mouth of the Canyon.
The Classics
Mountain Project's determination of some of the classic, most popular, highest rated routes for North Creek Canyon:
No established camping at all. Just a narrow dirt road to a dead end where the canyon starts. 10 miles up Nephi Canyon is Ponderosa and Bear Canyon Campgrounds though.
I am not really interested in established camping as much as just a place to throw down for the night. Is camping in North Creek or at the trailhead allowed?
Dispersed (undeveloped) camping is allowed by the road on the National Forest land (per forest ranger at SF Ranger Station). There is a small barricade at the end of the dirt road indicating the start of the Mt Nebo Wilderness boundary. Camping is also allowed in the wilderness following normal wilderness rules.
There are a couple good car camping spots on the left where the road splits a few hundred yards before the dead end. What a beautiful place with an amazing amount of rock.
