Before crossing the bridge to South Padre Island, stop in Port Isabel and check out its nearby attractions, including this popular pirate adventure cruise. Kids will enjoy swashbuckling fun like cannon battles, water pistol fights, sword duels and face painting as the sightseeing cruise encounters dolphins along its route. Families sail aboard the Black Dragon, a 17th century replica of a galleon. The ship sells snacks and drinks on board. Be sure to arrive an hour early to enjoy the pre-cruise activities that include magic tricks, fire eating and more on the outdoor patio, where food and drink are also available.
