Want to go to Yosemite in June? You can now make a reservation and here's how.

When we checked the booking system at www.recreation.gov at 11 a.m., there were still hundreds of spots available on all days except weekends in May. It's unclear whether May weekends are already fully booked or the park will release these dates later. 

The park is requiring visitors to have a reservation beginning May 21, the start of the busy summer season, to manage the number of people in the park and prevent the spread of COVID-19. The park typically doesn't require reservations for day-use visitors; this is a special system launched amid the pandemic.

Every visitor entering the park will need a day-use reservation, including annual and lifetime pass holders. The reservation is valid for three days with unlimited re-entries.

The reservation system will be in effect through Sept. 30.

You can book a reservation at www.recreation.gov.

"Reservations will go extremely quickly; be sure to have an account, be logged in, and ready to get a reservation promptly at 8 a.m. Pacific time," the park said in a statement last month when the reservation requirement was first announced. "If you have an annual or lifetime pass, be sure to specify that once your reservation is in the shopping cart."

Each day-use reservation is valid for one vehicle and the occupants of that vehicle. Find more details at www.nps.gov.

Visitors booking overnight stays will automatically be granted day-use reservations. This includes reservations for the Ahwahnee, Yosemite Valley Lodge, Curry Village, Wawona Hotel, Housekeeping Camp and National Park Service-managed campgrounds.

Day-use reservations are also included for all visitors with wilderness and Half Dome permits and visitors entering the park via YARTS buses and on permitted commercial tours, the national park said in a statement.
