The Ancient Bristlecone Pine Forest is home to the oldest trees in the world, bristlecone pines. Some of these living trees exceed 4000 years of age and exhibit spectacular growth forms of twisted and beautifully colored wood. The Ancient Bristlecone Pine Forest is a protected area high in the White Mountains in Inyo County located in eastern California. These trees grow between 9,800 and 11,000 fest above sea level in alpine conditions. There are two trails. We took the shorter Discovery Trail which is one mile in length. As you can tell from the images, we were threatened with rain the whole time and it was very cold and windy.
