Ocean Beach and Sunset Cliffs are also close to Sea World. Ocean Beach has a real 60s vibe. Sunset Cliffs is one of the least crowded beach areas in San Diego - but the beach is harder to get to and may disappear at high tide. To get to Ocean Beach from Sea World just take Sea World Drive to Sunset Cliffs Blvd. Follow Sunset Cliffs right into Ocean Beach and look for street parking. Go further and you are at Sunset Cliffs. You will know you are at Sunset Cliffs when you can see the Pacific Ocean to your right.
If you want ocean waves, the closest beach is Mission Beach. For more info on the beaches and directions to each of them visit:
