You can call for idywild campground 951-659-2607 or RivCoParks.org
RivCoParks.org / RivCoParks.org / RivCoParks.org At least a week in advance. MINIMUM! We reserve 3-4 weeks in advance for a good site. DO NOT EXPECT A DECENT SITE OR ANY SITE LAST MINUTE THIS TIME OF YEAR. THAT IS...IF YOUR ALLOWED UP THE MOUNTAIN. HWY 243 IS CLOSED.
Call is the best way
Also, if you drive to the camp site entire, there is a ranger at the check in and you can pay cash or check for a campsite.
