If you see a turtle or seal don't touch it and stay 10ft away from it or you'll be fined. Remember it's just trying to relax and get some sun same as you so give them some breathing space.
Po'ipu Beach has an area for little kids, shallow & protected. My 41/2 year old nephew and I both snorkeled for the first time there! (I went to the right of the little island that juts out)
Great for sunning or snorkeling. Wear watershoes as the beach is rocky in spots. Grab lunch at Breneckes deli conveniently located across the street from the beachpark.
There's a little sandbar right off of the beach, a perfect place to catch the sunset. Just be careful of the little waves that might get you more wet than expected!
Baby friendly lagoon near the playground (opposite Brennecke's restaurant). Great for kids; great for people who might not be too comfortable in water.
poipu beach is a great relaxing spot with some good snorkeling and a nice beach to lay out on. bring a few treats for the roaming beachchickens and get some shave ice!
