Overview
The bristlecone pines of the Spring Mountains are among the oldest living things on Earth, individual trees estimated at 1,500 to over 3,000 years old growing on the rocky ridgelines of what is now Humboldt-Toiyabe National Forest. The Bristlecone Trail is the most accessible route to this ancient forest, a 5.4-mile out-and-back that climbs from the Kyle Canyon recreation area through ponderosa pine and white fir to the twisted, gnarled bristlecone zone above 9,000 feet.
The experience of standing next to a bristlecone pine that was already a few centuries old when the Roman Empire fell is not easily replicated anywhere else in southern Nevada. These are not trees that look impressive in the way a giant sequoia does (bristlecones are typically under 30 feet tall) but rather trees that communicate extreme age through form: the dense, resinous wood; the multiple growing tops that respond to the loss of individual stems over the centuries; the storm-carved shapes that document thousands of winters of high-altitude exposure.
The trail begins at approximately 8,200 feet in Kyle Canyon, climbing steadily through forested terrain before reaching the bristlecone zone. Views over the Las Vegas Valley appear on the upper trail, offering one of the stranger visual juxtapositions in the national forest system: ancient trees older than most of human recorded history, with one of the country's fastest-growing cities visible below. For information on how national forests protect resources like these old-growth trees, see our national forest vs. national park guide.
The Route
Miles 0 to 1.5 (Lower Forest): The trail begins in ponderosa pine and white fir forest, climbing on a clear, well-maintained path. The trees here are relatively young by bristlecone standards. The gradient is steady.
Miles 1.5 to 2.5 (Bristlecone Zone): The trail enters the bristlecone forest. Individual trees become visible on the rocky ridgeline to the left. The most dramatic specimens are accessed via a short spur trail. Do not leave the trail to approach the trees closely.
Miles 2.5 to 2.7 (Upper Viewpoint): The trail ends at a rocky viewpoint with clear sight lines across the Las Vegas Valley and toward the Sheep Range to the northeast. This is the turnaround for most hikers.
The Return: Descend the same route.
When to Visit
May through October. The trail may have snow in April in cold years. Summer visits are comfortable due to the trailhead elevation (temperatures 25-35 degrees cooler than Las Vegas). Afternoon thunderstorms are possible from late June through August.
Check current conditions before visiting via our pre-trip guide.
What to Bring
Many hikers carry 1.5 liters for this moderate hike. Individual needs vary. Water is at the trailhead.
Consider bringing:
- A camera: the bristlecone forms are dramatic in morning or late-afternoon light
- A light jacket: the upper trail is breezy and cooler than the lower sections
- Sunscreen for the exposed upper viewpoint
Practical Details
A day-use fee or America the Beautiful pass required (as of 2026). Flush toilets and water at the Kyle Canyon recreation area trailhead. Dogs allowed on leash.
Veterans should review the America the Beautiful pass for veterans and our veteran benefits guide.
Getting There
From Las Vegas, take US Route 95 north to the Kyle Canyon Road exit (State Route 157). Drive west approximately 16 miles to the Kyle Canyon recreation area. The Bristlecone Trail trailhead is signed from the main recreation area road. The drive takes approximately 45 to 55 minutes from the Las Vegas Strip.
