About Upper Narrows
Overview
Upper Narrows Campground is located southwest of Grantsville, Utah, in South Willow Canyon at an elevation of 6,400 feet. Visitors enjoy exploring local trails.
Recreation
The multi-use Stansbury Front and Medina Flat Trails begin nearby, offering access to the rugged Deseret Peak Wilderness. Willow Creek offers rainbow and brown trout fishing.

This primitive campground is dispersed over a mile-long stretch of road. One walk-to group site, ideal for family reunions or church groups, is available for up to 50 people. A footbridge must be crossed to access the site from the parking area. Picnic tables and campfire rings are provided, as are vault toilets. Roads and parking spurs are dirt.
Natural Features
The remote desert canyon is forested with oak, maple, and juniper trees, which offer partial shade. Willow Creek runs alongside the site.
