Tamarack Flat and White Wolf Campgrounds
We don't have an opening date yet for these campgrounds. We will post here once an opening date is available. Tamarack Flat Campground is scheduled to close on October 15. White Wolf Campground is scheduled to close on September 25.
About 50% of reservations will be available up to two months in advance on the 15th of each month. For example, reservations for August 15–September 14 arrival dates will become available on July 15 at 7 am PDT on Recreation.gov.
The remaining 50% of reservations will be available each day, two weeks before arrival, at 7 am PDT on Recreation.gov. For example, reservations for August 15 arrivals will become available on August 1.
Yosemite Creek Campground
We don't have an opening date yet for this campground. We will post here once an opening date is available. This campground is scheduled to close on September 15.
All reservations will be available each day, four days before arrival, at 7 am PDT on Recreation.gov. For example, reservations for August 15 arrivals will become available on August 11 at 7 am PDT on Recreation.gov.
According to those rules, some of the dates for Tamarack Flat campground, at least, should be on sale now at Recreation.gov, but the campground is not listed on the site. I assume that, once they set a firm opening date for the campground, they will announce a date that the initial set of reservations ( Opening Day - July 14, which would have been available online on May 15) will become available.
