The southernmost city in Palm Beach county is also one of the more affluent communities in South Florida. Originally master planned by architect Addison Mizner, Boca retains a theme of Mediterranean revival/Spanish Colonial Revival buildings. Much of the best running in Boca Raton centers on the waterfront, with some nice paths along A1A. The extensive beach in the area is also runnable, in the right situations. For some good off-road options, there are good paths around Tradewinds Park and South County Regional Park.
Just the north, we have comprehensive guides to running in the Palm Beach/West Palm Beach area, and the Fort Lauderdale/Hollywood Beach area.
