There's nothing like swimming in this natural, geothermally heated pool next to the ocean with palm trees swaying overhead. Popular with locals, this immaculate 3-acre beach park has a ½-acre pond of fresh spring water mixed with seawater that's heated by volcanic steam. There's no sand, but there is smooth, rocky access to the ocean as well as the pool. Check with the lifeguard on duty, and heed all posted signs; this park sometimes closes temporarily due to possible waterborne bacteria. The parking lot fills up quickly. Amenities: lifeguards; parking (no fee); showers; toilets. Best for: swimming.
