The Mount Rainier National Park has miles of routes open to snowmobile riding. There are three snowmobiling areas: one in the northeast corner and two in the south.
In the north, snowmobiling is allowed on the unplowed 12 mile stretch of SR410 from the North Park boundary to the White River Campground.
In the southwest corner, snowmobiling is allowed on the 6.5 mile section of the Westside Road from the park road to Round Pass (riders are allowed on the Cougar Rock Campground loop, too).
In the southeast corner, snowmobiling is allowed from the Stevens Canyon Entrance to the road tunnel at Box Canyon.
Overall, Mount Rainier National Park is the 24th most popular snowmobile trail of all 28 snowmobiling rides in Washington.
