Cardiff-by-the-Sea State Beach is one of the most interesting and quirky state beaches. First of all, there's not a lot of acreage to this parcel of land. As we entered the parking lot of the beach, located north of some of favorite beachfront restaurants such as the Beach House in North San Diego County, we saw a teenager riding on a skateboard with an attached windsail of bright pink and white.  What can you do at Cardiff State Beach besides this unusual sport? You can surf, swim, picnic, walk and walk a pet. Located on the San Diego Coast next to the Pacific Ocean, Cardiff State Beach has a gently sloping sandy beach with warm water. The site offers swimming, surfing and beachcombing. Although narrow and rocky in many spots, Cardiff SB is extremely popular. One reason is that you can see the ocean from Old Highway 101 as you pass by. You can't help but want to stop to enjoy the sunny, San Diego County weather. There are no facilities at this beach, though if you dine next door at Restaurant Row, you'll be well attended. Pets are allowed at the beach on leash with the Golden Rule in enforcement. Clean up any messes your pet makes!
