Ali'i Saltwater Swimming Pool

"Our personal favorite of the Big Island’s unique swimming holes is the ocean swimming pool in Kona. This saltwater swimming pond gets filled (and cleaned out) by the waves of the Pacific ocean. When the surf is big you can sit on the edge and the waves will knock you into the pool, too much fun! It’s not that nice when the waves are small because the water is stagnant. To find it put “75-6106 Ali’i Dr Kailua Kona, HI 96740, USA” into google maps. This takes you to “Kona By The Sea” after you turn off Alii drive into the entrance, drive to the right where you will see a small parking lot marked as public parking. Walk down the very straight path from the road to the pool along the building. The state now owns this former private property and like the beach, the seawater pool is free and open to the public."
