Walnut Creek, CA, United States

With a population of 70,127, Walnut Creek is an affluent suburban enclave east of San Francisco. However, don't be fooled - the city's upscale veneer comes with a heavy tax burden and persistent bureaucratic headaches. Homeowners shell out a median of over $1.5 million for a single-family house, while renters face steep prices. And despite the mild Mediterranean climate, Walnut Creek's open space comes at a premium, with the city owning more protected land per capita than anywhere else in California. Still, for those seeking a cozy, manicured lifestyle in the East Bay, this well-connected commuter hub could be an ideal fit.
