"Beginning March 1, 2016, Camp Pendleton will require cyclists be pre-registered to gain access to and ride across the base. The registration process may be completed online and is good for 1 year, a valid U.S. or State Identification Card is required. Non-U.S. citizens will require a sponsor. A sponsor should be someone known to a rider. Sponsors have the responsibly to vouch for those they are requesting to gain access to this military facility. More information and a link to register online can be found on the base website: www.pendleton.marines.mil/About/BaseInformation/BaseAccess.aspx
It is up to each cyclist to determine their eligibility for entering the base by contacting the Base Access office: Base Access Control (760) 763-7604/7605; 6AM-4PM Monday-Thursday (closed Fridays); firstname.lastname@example.org
For cyclists who do not register in advance or who are not eligible to receive access to the base, you may legally ride on the shoulder of I-5 between Las Pulgas Rd. and Oceanside (Exits 62 to 54). For safety reasons, cyclists should exit and re-enter the freeway at the Aliso Creek Rest Area about midway through this stretch.
