Best place to go camping in Northern California in March?

Contact a National Forest district ranger office in an area of interest. Ask whether sites are open in March. You may be headed for areas buried under deep snow. National Forest campgrounds will likely be more quiet than the state parks. Consider dispersed camping on National Forest lands that is never closed, regardless of weather conditions. I frequently sleep in wilderness areas during winter.

Reservation campgrounds are available, however some Forest campgrounds are operated on a first-come, first-served system. The maximum stay in most campgrounds is 14 days with a 21 day maximum stay per Ranger District, per calendar year. Most campgrounds fill quickly during holiday weekends, therefore visitors should come prepared to camp in undeveloped areas.
