San Diego native here....I would recommend two walks in SD.u00a0 Keep in mind that I love the beaches.Walk around Fiesta Island.u00a0 That is located on the Bay side.u00a0 Excellent biking as well.u00a0 No commercial buildings, only distractions would be cyclists or other walkers.Walk the strand by the Hotel Del Coronado.u00a0 Again, excellent biking as well. You can rent bikes in the area.u00a0 There are a few to choose from.u00a0 Head South towards Mexico.When you are done....best Mexican food on the planet.. Old Town Mexican Cafe.u00a0 Order the carnitas.Steve
