     Yosemite Park is one of the most beautiful locations in the United States. A national park that covers

over 1,100 miles of land, it stretches across the western slopes (斜坡) of the Sierra Nevada mountains.

So it supports a wide variety of biological diversity (生物多样性).

     When exploring Yosemite, it's important to understand that you will see all sorts of wildlife, perhaps

even some of the more exotic if you're lucky. If you're the type of person who loves camping and being outdoors, go on an overnight or several days' backpacking trip, hike up to the falls, try out some rock

climbing, go biking and generally enjoy the amazing beauty of Yosemite.

     If you're a person who doesn't really like nature or enjoys it from a distance, Yosemite still offers many great opportunities. Stay in the luxurious Yosemite hotel and walk to the neighboring village to try an ice

skate. Check out the mall museum and go on several guided tours.

     Some must-see places in Yosemite include: El Capitan, one of the most famous rock-climbing areas in

the world; Yosemite Falls, easily the highest waterfall in North America at 2,425 ft; Ribbon Falls, the

longest single-drop water fall in the US at 1,612 ft; Mount Lyell, the highest point in the park, and many

other amazing sights.

     Thus Yosemite truly has something for everyone. If you have a chance, it's worth a visit, but events like swimming and boating are only available late spring through summer. In winter, there's cross-country

skiing, downhill skiing and snowshoeing, so fun activities are always available to all.
