California is the most populous state of America and probably one of the most well known states. It is situated on the West Coast of the USA, along the Pacific Ocean. California is bordered by Nevada to the east, Arizona to the southeast, Oregon to the north and Mexico to the south. It is also one of the largest states.
The Sierra Nevada mountain range lies in California. Here you'll find Mount Whitney, with 4421 m the highest mountain of the contiguous States, Yosemite Valley, famous for its glacially carved domes and Sequoia National Park, with its famous giant sequoia trees and the deep freshwater lake, Lake Tahoe.
There are excellent trekking possibilities in California.
