California State Parks announced today via their Twitter feed that the campground at Pfeiffer Big Sur State Park will be open for Memorial Day! Reservations will start at 8am Monday, May 18 on Reserve America. Open campsites are in South Camp and Weyland; Main Camp will be closed for construction all summer. If history is any indication, the reservations will all be claimed by 8:10am, especially since the number of campsites open will be limited. So set your alarm clocks!
