San Diego MLK Promenade- downtown San Diego - from the 5, exit at J and follow signs to Petco Park or Convention Center (on the waterfront) - this is a great urban walkway which runs next to the trolly tracks on Harbor Drive across the street from the convention center - walkway even takes you right through a really cool fountain- see photo below - parking can be tricky- either limited street parking or parking lots which can be pricey - no public restrooms on promenade - note: I recommend checking out the Gaslamp District which is filled with fun restaurants and stores.  The district runs north on 5th Ave (from Harbor Dr.) for several blocks.  Two crazy restaurants I enjoyed (not the best food but fun atmosphere) are Dick's Last Resort and Fred's Mexican Cafe- both on 5th Ave.  *very limited wheelchair accessible seating at Fred's

____________________________________________  Coronado Island Coronado walk/bike path along Coronado Bay * trail runs from Centennial Park/Ferry Landing to Tidelands Park, under the Coronado Bay Bridge and along Coronado Golf Course directions- to get to the island, take the Coronado Bay Bridge/75 over to the island - once on island, take first exit on right/Glorietta Blvd., you'll see Tidelands Park (you can park on street in this area on Mullinix or Glorietta Blvd) - or from Glorietta Blvd, take left onto 2nd Street, take right onto Orange Ave to Centennial Park (can park in parking lot there) -  a wide, paved trail used by walkers and bikers which has spectacular views of downtown San Diego and the Coronado Bay Bridge - enjoy watching tons of boats while hiking along this path - note: I suggest checking out the shopping district on Orange Avenue.  I totally recommend the Brownie Batter ice cream at Mootown Creamery on Orange.  Also recommended Island Pasta.
