Home to the highest peak in Washington, active volcanoes and serene lakes, it is no surprise that Mount Rainier National Park is one of the most popular outdoor recreation spots in America. Defined by jagged, towering mountain terrain, there is an abundance of hiking trails here that showcase some of the most beautifully unkempt wilderness. Ski down the slopes of crystal mountain when the weather is at its coldest, or follow the trails that surround Mowich Lake when the trees glow bright green. Head to Mount Rainier itself to try your hand at mountaineering, or to take yourself on a heart racing hike. Here, you can also see some of the best views in the park. When you visit, make sure to stay in an unusual accommodation to ensure your camping trip is extra special.
