I lived in San Diego for several years, and would suggest the following scenic destinations for touring:
- Oceanside to La Jolla
) this is the premier coastal route. Going north to south gives you the best unobstructed view of the Pacific the whole ride down. I always love to stop at Pizza Port in Solana Beach for pizza, cider, and their in-house brews. Lots of great family-owned business, food joints, cafes, and riders along the way - no matter which day of the week. La Jolla makes a good stop because it has a nice downtown area, shops, and a marine sanctuary right off the coast, and simply a gorgeous view, especially at sunset.
- Old Town to Ocean Beach to Cabrillo National Monument
) start in the historic part of town, sip some Margarita and enjoy the Spanish & Mexican influence of the city, then head along the San Diego river to Ocean Beach, a very chill beach neighborhood, down to Sunset Cliffs (another premier spot for sunsets!), and onward to the peninsula to the national monument. Great views of the city when looking back at the bay. Easy ride and you can easily combine this with other routes for a full day
- Balboa Park to Downtown/Gaslamp district to Coronado (via Ferry) and down to Silver Strand
) a little bit of everything! Very pretty and fun ride.
Further out, may require car transport:
- Anza-Borrego Desert State Park (spring bloom in the desert is amazing)
- Cuyamaca Rancho State Park
- Mount Laguna / Cleveland National Forest
- Julian (old mining town famous for its apple pies)
- Palomar Mountain State Park
