The bristlecone pines of Great Basin National Park have been radiocarbon dated up to 10,000 years old. When it was cut down, the bristlecone pine "Prometheus" was the oldest known living tree and is estimated to have been at least 4,800 years old. Many of the trees in the Wheeler Peak bristlecone grove have not been dated, but they are believed to be equally old.
The Bristlecone Trail is a relatively easy hike totaling 3 miles there-and-back. The trail is well maintained and easily accessible, which allows for even a beginning hiker to manage the adventure. A few sections have loose rock and quick switchbacks, but the trail remains tame throughout. There are also several resting points and benches along the way. The pine tree grove is an ideal spot for a snack or a longer appreciation of the area. The grove is a peaceful place with incredible views and wondrously old trees.
Remember that this hike is at a high mountain altitude, and the weather can change drastically without warning.
