Ojo De Agua is situated on the north eastern side of the islands isthmus. It has two pools fed by a cool natural mineral spring from an underground well in the upper pool. The continuous stream of fresh water flowing through the pools is said to have special healing qualities. The lower pool is over 40 meters (130 feet) long and around 2 meters (6.5 feet) deep making this crystal clear swimming lagoon, set in lush tropical surrounds, the perfect place to laze away an afternoon. There is a tightrope and tree swing for those kids-at-heart as well. Wooden lounge chairs and gazebos line the edges and a tropical restaurant overlooks the lush green surrounds. You can also choose to have your meals and drinks served poolside. Toilets and dressing rooms are provided, making this one of those magic little places where nature blends perfectly with hospitality and service. Entry to the reserve is around US$3 and meals and drinks are on par with the rest of the island (around US$5 for a substantial meal and around US$1.50 for a beer). This is a great place to relax (and recover) after climbing a volcano! Ojo de Agua lies centrally on the isthmus between the two volcanoes, still within walking distance from the Santo Domingo beach area.
The large trees surrounding the area give ample shade, and complete the relaxing setting with its hammocks and beach chairs. There is a restaurant on site which serves drinks and food. And some cocktails are served poolside in fresh coconuts!
