The pool is a natural basin in volcanic rock on Arikok's remote north coast, ringed by a wall of stone that the Atlantic breaks over and refills. Inside, the water is calm and clear. Outside, it is open ocean. That contrast is what makes it extraordinary.
You cannot drive there in a standard rental car: not "it's bumpy," but genuinely cannot. The realistic options are a guided 4x4 or UTV tour, a horseback tour, or a hot, exposed hike of roughly 45 to 60 minutes each way from inside the park. Tours are the normal choice with children, and they are also the safest, because guides read the sea conditions and turn back when the surge is wrong.
Be realistic about age. The 4x4 ride itself is rough enough that it is often the highlight for an eight-year-old and genuinely too much for a toddler. Getting into the pool means a short climb down wet rock. The surge inside the basin can push a small swimmer around. Life jackets, water shoes, and an adult within arm's reach are all sensible, and most operators provide the first two.
The pool closes when the sea is rough, which happens. Book early in your trip so you have a second chance if the first attempt is called off.
A secret swimming pool built by volcanic rock, filled by crashing waves. You can only reach it by 4x4, horseback, or a long hike, which makes it a real explorer's prize.
Remote; 4x4 or guided access, park admission required.
