  description: Bol is home to Croatia's famous Zlatni Rat beach—a stunning golden horn of pebbles that shifts shape with currents and storms. While the beach is world-famous, the surf is nearly non-existent, working maybe a handful of times per winter when Bora wind storms generate short-period Adriatic chop. Croatian surfers treat any rideable wave here as a miracle worth celebrating. This is Adriatic reality: stunning beauty, crystal water, ancient Roman history, and almost no surf.
