Rafael who was a former "gorilla fighter" and now the head ranger of the park was our guide. I do not know what if any he charges or was paid. I do know he was very knowledgeable and conducted a very informative and interesting tour. Note: (in case you are not bilingual) Rafael only spoke Spanish, our Overseas Adventure Travel (OAT) guide translated everything. There is also a very small (like 3 sections in a small building) museum in the city of Cinquera that you could also visit. The girl working there also gave a tour/talk; however, she only spoke Spanish. Our guide translated that too. There was a very small (i.e. nominal) entrance fee for the museum. Cinquera is a small and picturesque rural community located in the Salvadorian Department of Cabañas, 47 miles or 78 kilometers northeast of the capital city of San Salvador. During the war all the residents of Cinquera and the surroundings fled, leaving the area around it deserted. Beginning in 1992, the residents of Cinquera began to return, in order to rebuild and restore their village. The vision of Cinquera's residents was to restore their town and to preserve the delicate ecology of the surrounding forested area. The natural preserve was developed with the assistance of international relief organizations to preserve and protect the delicate ecological balance, along with the historical monuments. At present, the infrastructure includes the park, trails, uniformed guides and restored historical monuments, to support low-impact sustainable Eco-tourism benefiting the entire community while preserving the ambiance of the village with its important links to the Historical Memory of the Armed Conflict 1970-1992.

It's basically a protected nature reserve with lot's of hiking trails. A lot of the "civilian conflict" fighting took place there. The "tour" would be for how long you hire the local guide for. You can make your visit last as long as you want. I was there around 2 hours; however, there are additional miles of hiking trails that I didn't do. I didn't go in the water; but there were several people there that did. Many of them were locals with their families. The day I was there the water just didn't look real clean; maybe it was just run off from a recent rain, I did visit during the "rainy season". Also, there was a couple booths for changing by the waterfalls.
