After you arrive at Flamenco Beach, walk north along the beach and you'll soon come to a vivid relic of the now-defunct military presence on this island. A rusted tank, partly submerged in the water, sits on the sand. Colorful designs and symols have been painted on it, but it remains a completely (and intentionally) incongruous sight in this idyllic place. There is a second tank, not as colorfully painted and hidden behind the brush as you walk towards the submerged tank. It will be on a small hill on your left in the campgrounds area.
"These are pretty cool to see, but I don't think it's good to have metal corroding into their crystal clear waters. I think they should move it out of the water, and onto a hill, like the other one. Lots of cool artwork and graffiti. If you look inside the tanks, all you see is beer cans and bottles. Must be a popular spot to meet up with friends."
"A nice hike through the forest, with very nice views of the wildlife refuge and Puerto Rico mainland. Takes about 10-20 minutes depending on your pace. We didn't snorkel, so I don't know how good it is."
