Ojo de Agua, Isla de Ometepe

An amazing place to spend half a day. Recommended to go early as it gets very busy with locals. The water is stunning and a great temperature for swimming on a hot day. It's $3 entry still which is great. If you walk up the hill there is a good viewpoint and howler monkeys. The trails aren't well marked however.

A beautiful pastoral place. Admission is $5 per person. There is an arranged parking lot, a restaurant and good service. The water is relatively cool, there is Tarzan, swings in the water and plenty of shade, the place was a bit crowded but there was room for everyone to sit.

USA Traveler: My friend and I went here and had a wonderful time. Highly recommend! It's 10$ a person for a day pass. They have bathrooms at the parking lot but they also have showers and changing rooms closer to the "pool". It's apparently volcanic spring water, whatever it was was nice. There is a restaurant there and bar. Maybe a shop or two. Lots of chairs and tables to claim. We left our stuff out of sight for around 20 minutes and it appeared to be untouched. There's a rope to play on, swings in the pool, and a Tarzan swing to jump into the pool. No lifeguards. Wheelchair accessible to the pool. Some stairs that are wide going into the pool. The pool is surrounded by plants/jungle and even some go into the pool. Very cool! It was very shaded and so no sunscreen was needed.

Definitely worth a visit. 5$ entrance fee if you're a foreigner. The setting is a beautiful crystal clear waterpool in the midst of lush tropical vegetation. Only remark is that I expected it to be a bit more 'natural' while it's more like a swimming pool environment. Go on weekdays or the place will be swarmed.

I didn't go for a swim. I went for a hike around the platano plantation. The pool; however, was cool. There is a rope swing on a raised platform that one can launch into the water from. I recommend that you bring some rubber foot protectors as one of our group cut their foot on something sharp in the water.
