Conchi, also called the Natural Pool or Cura di Tortuga, is a natural saltwater tide pool in the north conservation zone of Arikok National Park. It is named after the turtles once seen in its waters. Volcanic pillow lava forms the rim, and the Atlantic breaks on the rocks outside.

A visit is a rugged outing. Most people reach the pool by 4x4, guided tour, horse or a long hike, then climb down more than 100 stone steps from the parking area. Inside the rock bowl, the water is calm enough to swim and snorkel on a quiet day. Plan a short stay and check conditions at the visitor center first.

• Do not swim when the waves are high; the pool can be dangerous then.
• Rangers may close the pool when surf is up and rocks are slippery. Check conditions at the visitor center first.
• Bring water and shade of your own. None is sold inside the park along the trail.
• If you drive a 4x4, a spare tire is advised.
