What attracted me to St. Augustine was its Fountain of Youth. Legend has it that Spanish conquistador Juan Ponce de Leon swashbuckled ashore in 1513 looking for gold. Reporting back to King Ferdinand empty-handed, he swore he’d located the mythical Fountain of Youth. The perpetually spouting mineral spring still draws the hopeful here.I swigged bottle after bottle of the elixir, sold at the wonderfully vintage, yoga-serene Fountain of Youth Archeological Park. (fountainofyouthflorida.com)Shocker: it doesn’t work. But in St. Augustine I found youth of another kind.
