Visiting D Beach at Gateway National Recreation Area in Sandy Hook was one of the best beach experiences I've had in NJ in a long time. The beach offers clean and peaceful surroundings, and a glimpse of New York City's skyline to the North is a fun treasure hunt for the kids. The facilities were in excellent condition, and we felt very safe with our children there, thanks to the impressively vigilant lifeguards, who not only look out from their towers but also spotted them walking the beach between towers occasionally. A must-see spot for families or anyone looking to enjoy nature and a day at the beach. Beware of the friendly birds though; they might just be a little too friendly! Feed them at your peril; they have a way of calling in reinforcements and leaving behind 'gifts.' Enjoy!
