route to take and what views to watch really brought us closer together.

　　The great thing about nature is that, it's just you, the views, and the people around you. There's nothing to bother you and it's the best way to relax and enjoy yourself. Yosemite has 5 of the world's highest waterfalls, and about 300 lakes. The structure of each mountain is incredible; it's formed in ways that almost take your breath away. Some of them are of a deep dark color with waterfalls forming; some are formed with spots of green peeking (窥探) out. It's definitely something you wouldn't want to miss.

　　Yosemite isn't the only great national park but based on my experience I highly recommend going out and enjoying nature with family and friends. It's a great time to bond, laugh, and take in what Mother Nature offers.
