Thundering Surf Water Park is the classic family fallback in Beach Haven when everyone needs a change from sand and surf. It has water slides, a lazy river, splash areas, and mini-golf, all on a scale that fits Long Beach Island's beach-town mood.
It is busiest on hot afternoons and during peak summer weeks, so arrive early if you dislike lines. For travellers with children it can rescue a windy beach day; for everyone else, it is useful mostly as a local landmark in Beach Haven's cluster of amusements.
