Jumbo Rocks Campground lies amid the huge, steep rock formations for which Joshua Tree National Park is known. Close proximity to many boulders and rock formations, it is a popular camping location for families with kids. Jumbo Rocks is one of four campgrounds in the park that can be reserved during the busy winter season; it is open on a first-come, first-served basis from June 9 through August 30. Travelers who enjoy warm, dry winters flock to Joshua Tree from October through May, when temperatures hover between 70-90 degrees during the day and drop to a 40-60 degree range at night. Summer is the park's off-season due to the uncomfortably-high desert heat. Jumbo Rocks is at an elevation of 4,380 feet.
Reservation Cancellations & Changes
Cancelling a Reservation: Customers may cancel their reservation prior to arrival both on-line and through the call center. A $10 service fee will be withheld from any refund for a cancellation. Depending on when you cancel in relation to your arrival day, it may be considered a late cancellation (see below).
Changing an Existing Reservation: When changes are made prior to the cut-off window:
If a customer wants to switch dates that are entirely outside of the original reservation dates, there is a $10 change fee.
There is no change fee if a customer extends or shortens a reservation, as long as the change includes dates from the original reservation. If they choose to depart early, they may forfeit the recreation fee for the day of departure.
There is no change fee if the customer wants to switch sites that are the same price with the same reservation dates in the same facility.
If a reservation is made that includes dates beyond the maximum booking window, that reservation cannot be changed until 18 days have passed from the original booking date.
Late Cancellations or Cancellations within the Cut-off Window
Individual Campsites: A customer who cancels a reservation the day before or on the day of arrival will pay a $10.00 service fee AND forfeit the first night's use fee (not to exceed the total paid for the original reservation). Cancellations for a one-night reservation will forfeit the entire amount paid and will not be subject to an additional service fee.
Changes or Cancellations within the Cut-off Window: Once a reservation date has begun, customers cannot change a reservation using the online system or through the Call Center (see below for early departures). If the location is staffed, on-site personnel may or may not be able to assist with changes or cancellations (check with local staff).
Overnight and Day-Use Facilities: A no-show customer is one who does not arrive at a campground and does not cancel the reservation by check-out time on the day after the scheduled arrival date (or for day-use facilities, by check-in time the day of arrival). Staff will hold a campsite until check-out time on the day following the arrival date and will hold group day-use facilities until check-in time on the arrival date.
No-shows are assessed $20.00 service fee and forfeit the first night’s recreation fee for a campsite or forfeit the entire day-use fee for a day-use facility.
