If you are not paying for a full hook up site, there is a $5.00 dump fee. The California Department of Transportation restricts all roads leading to Jojoba Hills to motorhomes that are 40 ft or less in length. However, trailers are not restricted. Potable water and rinse water (non-potable) are available at this RV dump station. To get to the dump station, you can take I-15 and then take Hwy. 79 South for 17 miles. The resort is located on the left, about 1/2 mile west of Aguanga.
