Hello, I went 4 years ago and there are sites for tents and a car for $20, there is not a good signal for cell phones but there is WiFi near the office, there are also showers with hot water and an area with a refrigerator and microwave. In general, the place is very complete and the comfort depends on you. In my case I have gone 3 times without a reservation because it was difficult for me to make it by phone. Once I arrived at night and there was no one in the office, but I went directly to a place and the next day I paid my stay when I saw the man.
