About this spot

Changing rooms, showers, shops and restaurants are all provided on site, so being able to spend the day with almost no gear is a reassuring point. Enter at lunchtime and you can secure a spot before the peak crowds while enjoying water play right up to closing in the evening. Spend time filled with the openness only a seaside town can offer.
