Overview
The Spring Mountains rise from the Mojave Desert northwest of Las Vegas to nearly 12,000 feet, creating a sky island ecosystem in Humboldt-Toiyabe National Forest that supports ponderosa pine, white fir, and bristlecone pine above the surrounding desert scrub. The Las Vegas Watershed Loop uses the Cathedral Rock Trailhead in Kyle Canyon to explore the ponderosa pine and fir forest zone at approximately 7,000 to 7,800 feet, offering one of the best easy loops accessible from Las Vegas in a comfortable 6-mile circuit.
For Las Vegas residents and visitors, the Spring Mountains are primarily known as a temperature refuge. The 25 to 35 degree difference between the valley floor and Kyle Canyon is real and reliable, and the forest provides genuine shade that the desert below cannot. The trail corridor also passes through a landscape that looks nothing like what most visitors expect from Nevada: the ponderosa pine forest, the rocky canyon walls, and the cool air create an environment that feels closer to the Rocky Mountains than the Mojave Desert.
The loop is accessible for most of the year, with the lower sections of Kyle Canyon snow-free from March or April through November. Summer is the most popular season, when Las Vegas heat drives visitors upslope. The trailhead has facilities and is the most developed hiking area in the forest's Nevada portion.

The Route
Miles 0 to 1.5 (Cathedral Rock Approach): From the trailhead, the trail climbs through ponderosa pine and enters a rocky draw below the Cathedral Rock formation. The canyon walls are prominent in this section. The gradient is moderate and steady.
Miles 1.5 to 3.5 (Upper Loop): The loop's upper section gains the highest elevation, passing through a zone of white fir and mountain mahogany. Views across the Las Vegas Valley open on clear days. The trail junction divides the loop here; the route continues clockwise.
Miles 3.5 to 5.0 (West Return): The trail descends the western arm of the loop through ponderosa pine back toward Kyle Canyon. This section is more open and sunlit than the shaded east arm.
Miles 5.0 to 6.0 (Canyon Return): The trail re-enters the lower canyon and returns to the trailhead.
When to Visit
April through November at this elevation. Summer is peak season for temperature relief from Las Vegas. The trail can be icy in January and February. Spring (April-May) brings wildflowers in the canyon. Fall color appears in October.

What to Bring
Many hikers carry 1.5 liters for this loop. Individual needs vary. Water is available at the trailhead.
Consider bringing:
- A light jacket even in summer: temperatures can drop quickly in the afternoon
- Sunscreen for the exposed upper sections
- Comfortable walking shoes
Practical Details
A day-use fee or America the Beautiful pass is required at the Cathedral Rock Trailhead (as of 2026; verify current requirements). Flush toilets and water at the trailhead. Dogs allowed on leash.
Veterans and military families should review the America the Beautiful pass for veterans for fee coverage and our veteran benefits guide.
Getting There
From Las Vegas, take US Route 95 north approximately 20 miles to the Kyle Canyon Road exit (State Route 157). Drive west on Kyle Canyon Road approximately 16 miles to the Cathedral Rock Trailhead in the Kyle Canyon recreation area. The drive takes approximately 45 to 60 minutes from the Las Vegas Strip. Cell service is limited above the valley floor but a Forest Service visitor center in Kyle Canyon has current conditions information.
