In other campgrounds, site size varies and many sites are not suitable for very long RVs. There is a camping limit of 14 days during the period from June 14 to September 15 with a total of 30 days per calendar year. For specific information on each campground please use the links below:

BUSIEST TIMES
All park campgrounds often fill up on Saturday nights in July and August. However, chances of finding a campsite from Sunday afternoons through Friday afternoons are very good with the exception of Lodgepole which may have only a few sites available during midweek. See "Group Campsites" below for information on sites for groups of 7 to 50 and follow links for details.

THIS IS BEAR COUNTRY. Food storage is required!
All campgrounds in these parks may be visited by black bears. With their excellent intelligence and sense of smell, they easily learn to seek human food. Then these usually shy animals may damage cars, coolers, and tents to get at it. If a bear gets very destructive, it must be killed.
You can prevent this! Always follow all requirements to store your food properly year-round.
Campgrounds offer metal bear-resistant storage boxes (box sizes are listed for each campground; avoid bringing coolers that won't fit). Check park bulletin boards for instructions when you arrive, or click the "Black Bear" link on the right for more information.
While black bears can be dangerous, it's our food, not us, that they are after. There are no grizzly bears in these parks.    more...

VEHICLE LENGTH INFORMATION:
MAXIMUM VEHICLE LENGTH — Legal length limits on the Generals Highway are 40 feet (12 m) for single vehicles or 50 feet (15 m) for vehicles plus a towed unit. If you are towing a smaller vehicle, consider camping in the foothills and using the smaller car to explore.

VEHICLE LENGTH ADVISORY — The 16 miles of road from Ash Mountain to Giant Forest includes 130 curves and 12 switchbacks. There is a vehicle-length advisory for the 12 steepest miles within that stretch. From Potwisha Campground to the Giant Forest Museum, the advised maximum vehicle length is 22 feet (6.7 m). The alternative: take Highway 180 from Fresno to Grant Grove, then turn south on the Generals Highway.

FIRE, SMOKING, AND WATER RESTRICTIONS:

Fire danger and drought are regular summer issues here. Look for postings or ask about fire restrictions before you ignite any flame in the summer; they may be imposed at any time. As for drought, water may be limited during very dry summers and water use may be limited at RV sanitary dump stations or other locations. Call before you come if you hope to rely on park water supplies: 1-559-565-3341.
