The roadway beyond the North Grove that leads to the Stanislaus River and South Grove is closed from approximately mid-November to mid-April. Twelve campsites are kept open in the North Grove Campground all winter long, with additional sites becoming available as weather conditions permit.

In addition to the popular North Grove, the park features South Grove, a five mile hiking trip through a spectacular grove of giant sequoias in their natural setting. Other attractions in the park include the Stanislaus River, Beaver Creek, the Lava Bluff Trail and Bradley Trail.

The park also houses two main campgrounds with a total of 129 campsites, six picnic areas and hundreds of miles of established trails. Activities include cross-country skiing, evening ranger talks, numerous interpretive programs, environmental educational programs, junior ranger programs, hiking, mountain biking, bird watching and summer school activities for school children.

Dogs are welcome in the park on leash in developed areas like picnic sites, campgrounds, roads and fire roads. Dogs are not allowed on the designated trails, nor in the woods in general.
