The Hurricane Ridge Visitor Center is a great place to start. Located just before the end of the road, stop here for brochures, maps, snacks, and tips regarding your stay. It is open daily in the summer, and on Saturday/Sunday when the Hurricane Ridge Road is open during the remainder of the year.
Hurricane Ridge has a number of hiking trails, from ridgetop traverses to steep trails that descend to subalpine lakes and valleys. Obstruction Point Road (weather and snow permitting, open from July 4 through October 15), branches off right before the Hurricane Ridge Visitor Center, and provides access to a variety of trails as well.
During the winter months, snow enthusiasts enjoy the winter scenery, along with snowshoeing, cross-country skiing and sledding. Weather permitting, the Hurricane Ridge Winter Sports Club operates two rope tows and a Poma lift.
During the spring, wildflowers cover the ground of the subalpine meadows and blacktail deer are often spotted grazing. Sunrise and sunset on a clear day provide magnificent panoramic views of the park.
