Walkable yet rustic: La Mesa, WalkSanDiego.org named this East County gem the most walkable city in San Diego County, thanks in large part to its upgraded intersections and pedestrian-friendly downtown village. Just up the hill in hip Mount Helix, sidewalks disappear altogether in favor of winding hillsides dotted with boulders, trickling creeks, and ranch-style homes that stretch out over acres (yes, acres) with views out to Coronado. Even with antique shops, unique boutiques, and the neighboring behemoth Grossmont Center, La Mesa still feels quiet, like a peaceful suburban haven enjoying just a splash of urban culture.
