As has been mentioned, the blowing rocks really come to life during high tides and high wave action. We haven't seen that yet, but the rocks certainly have life in them on all but the calmest of days, and the beach is quite serene. Take time to walk the trail northward through the dunes. Some important details. The parking lot is closed by 4:30, so don't come late (there are access points a mile or two south where you can park later -- and where there are some beautiful, much photographed rocks, as well.) There is a two dollar charge for those who happen to be older than twelve. The nature center is small but has interesting exhibits. And don't expect to bring food to the beach; sorry, not allowed.
