German comment "ist geschlossen" means "is closed". It seems that there was some major construction work going on in 2017, when they built a large number of wooden cabins. It is still listed as "Camping Montaña Roja" on official websites, but it kind of looks like you're forced to rent one of the cabins if you want to stay there. Not sure if that still qualifies as camping grounds.

TL;DR: probably not closed, but probably needs re-survey
