Del Norte Coast Redwoods State Park

The Last Chance portion of the California Coastal Trail off the Redwood Highway near Enderts Beach is a moderate 12 mile round trip. With deep forests, beautiful meadows, and ocean vistas, this is a trip not to miss. The trailhead is located 5 miles south of the main entrance to the Del Norte Coast Redwoods State Park. This portion of the state can get more than 100 inches of rainfall a year, so check at the ranger station before starting out for trail conditions and closures.

Jackson Demonstration State Forest

Try the Caspar/Little Lake Road between Caspar and Highway 20. It's a rugged 16 mile round trip through a variety of forests, canyons, and streams. There are also many other smaller roads through the area, so you might want to stop and get a map before you hit the trails.

Smith River National Recreation Area

The Old Gasquet Loop Road covers 23 strenuous miles of dirt road through Panther, Grassy Flats, and Cedar Creek up to the 2000 foot level of Cold Spring Mountain. This is a long and rough ride over little used forest service roads. To get to the trailhead, go west past Gasquet about a half mile from the ranger station, south on Middle Fork Road for about a half mile, turn right at the fork to Old Gasquet Toll Road, then west a quarter mile to the end of the road and the beginning of the trail. Check in at the ranger station for maps and road conditions before starting out.
