Starting from Wheeler Peak Campground at 10,000 feet, this trail passes through a grove of ancient bristlecone pines — some over 5,000 years old — making them the oldest living organisms on Earth. The gnarled, ancient trees are profoundly moving, and the 12,000-foot peaks above provide dramatic backdrop.
The Bristlecone Trail at Wheeler Peak in Great Basin National Park provides access to one of the finest groves of ancient bristlecone pines in the world, trees that are among the oldest living organisms on Earth, in a dramatic high-altitude alpine setting in eastern Nevada. Great Basin National Park is located near Baker, Nevada, approximately 290 miles north of Las Vegas via US-93 and US-6, near the Utah border in one of Nevada's most remote landscapes. The trailhead begins at Wheeler Peak Campground, reached via the 12-mile Wheeler Peak Scenic Drive that climbs from the park's main visitor center to approximately 10,000 feet elevation. A $35 per-vehicle park entrance fee applies; no separate hiking permit is required. No public transit serves the park; a personal vehicle is essential. The campground has flush toilets and running water, with day-use parking available for hikers not staying overnight. From the campground the trail ascends gradually through Engelmann spruce and limber pine forest on a well-graded, clearly signed path. The terrain is rocky but manageable, and the trail surface is maintained in excellent condition. At approximately one mile the forest thins and the trail enters the ancient bristlecone pine grove, a ghostly landscape of silver-gray deadwood and living gnarled specimens clinging to the rocky slope at approximately 10,800 feet elevation. The bristlecone pines here (Pinus longaeva) have been dated at up to 5,000 years old. One individual named Prometheus, felled in 1964, was found to be 4,862 years old at that time, then the oldest known living tree ever documented. Living trees in the current grove may be similarly ancient. The combination of extreme cold, rocky alkaline soil, and persistent winds that makes this terrain hostile to most species is precisely what allows bristlecones to thrive, as their dense resinous wood resists insects and disease across millennia. The high-altitude setting means even this shorter trail can cause noticeable breathlessness in visitors arriving from lower elevations the same day. The trail ends at the grove; hikers return the same way or connect to the Alpine Lakes Loop and Wheeler Peak Summit Trail from the same trailhead.
Trail facts
- Trail area
- Great Basin National Park, Baker
- Best season
- Late June to mid-September (snow typically clears by late June)
Highlights
- 5,000-year-old bristlecone pines
- Dramatic mountain scenery
- Accessible alpine hike
- Connects to Wheeler Peak Summit trail
Tips for visiting
- The trailhead is at 10,000 feet; allow extra rest breaks if arriving from lower elevations on the same day
- Carry layers; temperatures at 10,800 feet can be 25 to 30 degrees Fahrenheit cooler than in the valley even in summer
- Visit on a clear day for views of Wheeler Peak's glacial cirque above the bristlecone grove
- Look for the Prometheus interpretive marker in the grove indicating where the famous ancient tree stood
- Carry at least 1 liter of water per person; no water is available on the trail after leaving the campground area
- The Bristlecone Trail connects directly to the Alpine Lakes Loop and Wheeler Peak Summit Trail for those wanting a longer day
When to visit
Late June through mid-September when snow has cleared from the trail. The grove is most atmospheric in September when summer crowds thin and the light softens in the lower sun angle.
Accessibility
The Bristlecone Trail involves 200 meters of elevation gain on natural rocky mountain terrain at high altitude; it is not accessible to standard wheelchair users or strollers. The rocky surface throughout and the elevation preclude the use of mobility aids.
Frequently asked questions
How old are the bristlecone pines in Great Basin National Park?
Individual trees in the Wheeler Peak grove have been dated at up to 5,000 years old. The species is the longest-lived non-clonal organism on Earth. Prometheus, felled in 1964, was 4,862 years old, a discovery that helped spur protections for the remaining ancient groves.
Can visitors touch or collect bristlecone pine wood?
Collecting any natural material including wood, bark, or rocks is prohibited in Great Basin National Park under National Park Service rules. The bristlecone pines are fragile cultural and natural resources; visitors should observe from the trail without touching the trees or their deadwood.
Is the Bristlecone Trail suitable for children?
Children aged 5 and older who are comfortable hiking can generally complete this trail, but the 10,000-foot elevation may cause fatigue more quickly than expected. Families should carry water, snacks, and warm layers and allow for a slower pace than at lower elevations.
What is the difference between the Bristlecone Trail and the Wheeler Peak Summit Trail?
The Bristlecone Trail is a shorter, easier hike (4.8 km, 200 m gain) focused on the ancient pine grove at 10,800 feet. The Wheeler Peak Summit Trail (13 km, 700 m gain) continues above the grove to the 13,063-foot summit. Both begin from the same trailhead at Wheeler Peak Campground.
Is Great Basin National Park crowded in summer?
Great Basin is one of the least-visited national parks in the contiguous United States. Even at summer peak the trails are rarely crowded compared to parks like Zion or Yosemite. The remote location discourages casual tourism; weekdays are especially quiet.
