Yosemite National Park

Yosemite Valley offers incredible beauty

Yosemite National Park is one of the most popular tourist attractions in the USA. This is partly because of its proximity to the population centers of Los Angeles and San Francisco but is mostly due to the incredible natural beauty of Yosemite Valley. The glacially eroded alpine valley is just 8 miles long and less than one mile wide with sheer granite walls rising vertically over 3000 feet (1000 meters) on either side. Nine magnificent waterfalls cascade into the valley. Five of them are over 1000 feet (300 meters) high including the 2425 feet (800 meters) Yosemite Falls. Yosemite Park actually encompasses about 1200 square miles (3000 sq. km) and includes many other natural attractions, but most tourists visit only Yosemite Valley or the Mariposa Grove of Giant Sequoia trees near Wawona at the southern entry.

Due to its immense popularity, Yosemite Valley frequently becomes very crowded in the summer months and on weekends throughout the year. The single loop road that circles the valley floor often becomes choked with traffic on popular summer weekends. The National Park Service provides a free shuttle bus around the loop from various parking areas outside of the valley. They are considering a ban on automobile traffic within the valley; but so far, the shuttle bus is just voluntary. It is possible to visit Yosemite by taking the Amtrak train to Merced and then boarding a bus to Yosemite, but automobile travel is the most convenient method of exploring this vast natural wonder.
