The phrase "urban bike ride" may stir up gritty images of fixies swerving through traffic, scoping grimy graffitied warehouses, and hopping curbs to find their way through the concrete jungle. But this is Miami, the nation's only urban area nestled next to two national parks, and its urban cyclists deserve a gloriously green trek to match. Enter Old Cutler Road, the handsome, mansion- and royal-palm-lined street that cuts through moneyed estates and passes some of Miami's finest parks along the way. Start your ride at Fairchild Tropical Botanic Garden and head south beneath the lushly shaded foliage, hook east through some of the best old architecture in Miami-Dade County, and roll south for just under six miles until you hit the Deering Estate at Cutler, the glorious Old Florida home of Charles Deering, on the waterfront. An urban ride that goes from tropical garden to waterfront estate? Must be in Miami-Dade, son.
