One of the safest swimming beaches on Kauai north shore thanks to the longest fringing reef in the state that protects the shoreline from waves. The water is calm, warm, and shallow for a long way out making it excellent for young children. The reef creates a natural lagoon that is great for beginning snorkeling. The beach is long and the campground at one end makes multi-day stays possible. The mountain backdrop and quiet setting feel like classic old Hawaii. Windsurfing is popular here and fun to watch.
