I will be driving to La Jolla. I want to visit the beaches to see the seals and sealions and probably explore downtown while we are there. Possibly get lunch. What is parking like in these two areas? Is there a central location to park and walk to both locations? Also is there a main street or block where shopping and restaurants are? We will be coming from Cabrillo. Is there a scenic drive? It looks like Mapquest has me getting on the interstate.
