Downtown San Diego is located on San Diego Bay. Coronado Island and Point Loma separate the bay from the ocean. Ocean Beach is on the west side of Point Loma. Mission Beach and Pacific Beach lie between the ocean and Mission Bay, a man-made aquatic park. La Jolla, an affluent community, lies north of Pacific Beach. Mount Soledad in La Jolla offers views from northern San Diego County to Mexico. Mountains rise to the east of the city, and beyond the mountains are desert areas. Cleveland National Forest is a half-hour drive from downtown San Diego. Numerous farms are found in the valleys northeast of the city. The city of San Diego itself has deep canyons separating its mesas, creating small pockets of natural parkland scattered throughout the city.
