   Once a bathing spot for the royals, this stunning natural pool is now a popular summertime attraction. To get there, you'll need to take a 15-minute hike across slippery lava rocks, so wear a good pair of shoes. In summer, the pool resembles a large hot tub and the waters are calm and clear. During winter, however, the water can be treacherous, so avoid visiting during those months; the pool may even be closed. Before you go, be sure to check the surf report online, and only attempt the hike down if the waves are less than four feet high. – Tripadvisor See more..
