Los Tintoreros is a national park just south of Puerto Villamil. There are great snorkling opportunities in the area as well as an interesting walk opportunity on the islands.
NB: Being a national park, you cannot get there on your own but will need a guide to accompany you.
Starting point is a good place to land your boat when visiting - it is not hiding the cache though. you will have to solve the puzzle below to come to the right coordinates. T rating reflects the difficulty getting to the island. The cache itself is more T1½.
If you are lucky, you may come at a time where sharks and sea-turtles visit a nearby canal on your way. This site is close to the cache location.
