We had a very difficult time finding the actual Charco and when we did the only way to access it was by swimming into muddy water. We opted not to swim and just observed the Charco from a high point on the "trail".
There is very little signage in the area directing you to the Charco or any "trails". I use quotation marks because there really are no trails, just the access road used by the water authority.
At first, we drove completely past the Charco, despite using the supposedly exact GPS coordinates. We stopped and asked a guy doing yard work around his house for directions and that got us on the right road. We then parked, as suggested by other reviewers, at a private lot at the top of the hill where a local homeowner had small lot parking available for $3. We then walked down the hill to the river. There's a tiny overgrown sign directing you to the Río. We went down the steep hill and saw the water authority's little blue station. Then we wondered how to get to the Charco. There are no signs, nothing. We followed what appeared to be trail along a cliff but had to turn back at an impasse. The "trail" was very overgrown and full of fallen trees and brush. We then ran into some local youth and they directed us to follow the river. We walked then waded down the river for awhile. Note, if you're going to try to check this out, you will want some good water shoes with lots of traction. We reached a small area where the youth appeared to have camped earlier. Here's where you could potentially swim further in and observe the caves. I climbed back up on the "trail" and could see some of the vista I'd seen on YouTube and Instagram. Looks nice but if you don't want to swim in questionable looking water, not the best.
The complete lack of trails and appropriate signage seriously detracted from our experience. Unless you're a hard core adventurer willing to both hike and swim with the appropriate gear, I would not recommend visiting this Charco. Also, as there are no actual trails I would not recommend this for kids or anyone with mobility issues. Go the El Yunque instead where the trails are paved and well maintained.
