Cottonwood Group Campground is one of the best places in Joshua Tree National Park for stargazing and wildflower viewing. The group campground is part of the main Cottonwood Campground and has three sites that are by reservation only. It is one of three group campgrounds in the park and the only campground that lies in the southern section. To get the most out of your visit Plan Like a Park Ranger

Travelers who enjoy warm, dry winters flock to Joshua Tree from October through May, when temperatures reach between 70 to 90-degrees during the day and drop to 40 to 60-degrees at night. Summer is the park's off-season due to the uncomfortably high desert heat. Cottonwood Group Campground is at an elevation of 3,000 ft. and has little shade from vegetation; however, there are picnic shelters that provide shade at each site.

Recreation

Stargazing and wildflower viewing are among the most popular activities at this facility. Several hiking trails leave from the campground and several more trailheads are within a 1-2 hour drive.

Facilities

There are three group sites, each with a picnic shelter. There are no electrical hookups, and RVs and habitable trailers are prohibited. Drinking water and flush toilets are provided.

Natural Features

The landscape around Cottonwood is that of the Colorado Desert, which encompasses the southern edge of the park and a large portion of Southern California. Rather than being surrounded by large rock formations and uniquely-shaped Joshua trees, like campgrounds in the northern section, this facility overlooks flat, open-desert shrubland. It is also further from towns or cities that would contribute light pollution. As a result, it offers wide, dark and uninterrupted views of the night sky that draw astronomers and amateur sky watchers alike.

Cottonwood is at a lower elevation than other campgrounds within the park, so desert wildflowers begin to bloom earlier in the spring than in other locations. Flowering occurs anytime between the beginning of February to the end of March; timing varies depending on the amount of winter precipitation and the arrival of warm temperatures.

Nearby Attractions

The General Patton Memorial Museum, a U.S. military history museum, is just over 12 miles away in the town of Chiriaco.

Charges & Cancellations

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

Group Facility : Customers who cancel a group overnight facility reservation less than 14 days before the arrival date will pay a $10.00 service fee AND forfeit the first night's use fee.

No-Shows

Overnight Facilities: A no-show customer is one who does not arrive at a campground and does not cancel the reservation by check-out (noon) time on the day after the scheduled arrival date. Staff will hold a campsite until check-out time (noon) on the day following the arrival date.

No-shows are assessed $20.00 service fee and forfeit the first night’s recreation fee for a campsite.

*Note: the entire reservation will be cancelled for no-shows.
