If you are in Poipu and are looking for a less crowded beach option check out Baby Beach. Take the round-a-bout towards Spouting Horn on Lawai Road. Turn left on Hoona Road and Park along lava rock wall. Look for the yellow pipe for Beach access down the stairs.
This beach is protected by an outside reef and has shallow pools for small keiki to play. You can also explore the tide pools, play in the sand, and snorkel. The beach has no facilities but Lawai beach facilities are just up the road in case. Although there is no lifeguard and little shade it is well worth the peace and serenity this beach provides.
Remember to follow the beach safety guidelines, check surf and weather reports for current conditions, and observe posted signage. Keep a constant watch on keiki who are playing in or around the water. Never leave children unattended. Small children should wear safety floatation devices unless they are avid swimmers and are being closely supervised.
