Yosemite National Park is offering more sites for campers, including a campground that's been closed for 13 years.
Park officials said Yosemite Creek Campground is open for the first time since 1997.
The campground was closed after a bridge was destroyed in a flood. Crews have finished rebuilding the bridge, making the campground once again accessible.
Several campgrounds along the Tioga Road and the Bridalveil Creek Campground on the Glacier Point Road, which were closed during the winter of 2009, are also open again.
Even with the additional sites, officials say all campsites on the reservation system are booked through the summer.
People who want to camp at the first-come, first-served campgrounds are urged to arrive early in the day.
