I love Nantasket! It gets a bad wrap, but it actually isn't that bad at all. I would say check the high tide times prior to your trip. We were there for abnormally high tides and literally everyone was pulling their items up onto the rocks near the sea wall. We finally left because there were just too many people in a small area and we had small kids. If you go to the area all the way to the right (if looking at the ocean) there is more space. Wish we had been there! Nice little beach shops in the area, great for a family day!!
