Located on the northern end of the city of Oceanside in San Diego County, Del Mar Beach at Camp Pendleton - also known as Del Mar Beach & Marina - is a private, long, and wide beige sand beach. The beach is positioned on federal land in Camp Pendleton South and is exclusively accessed by military personnel and their families. The beach has a beautiful background of many oceanfront cottages, an RV park, and several restaurants, which together offer many Instagram-worthy views of the vast Pacific Ocean.
