The Chincoteague Pony Swim is an annual saltwater roundup of the famous wild ponies of Assateague Island off the Delmarva Peninsula. The volunteer firemen of Chincoteague Island, Virginia, ride to Assateague, round up as many as 300 ponies, and then guide them into the water to swim across the channel to Chincoteague. The next day some foals are sold at auction and the rest of the herd swims back to Assateague. A week of festivities surrounds the roundup, and tens of thousands come to watch the excitement from land and small boats. Discuss
