We went there for the festival, it's a beautiful location,
don't forget to take a dip in the river :D
like mentioned before; don't drink the tap water.
The men's room toilets lack toilet seats and you need to bring your own toilet paper or buy a roll in the shop.
the food is ok, but if you can go to the nearest town (san nicolas del puerto) and grab a bite to eat at the restaurant La Atarazana there they have amazing food at really cheap prices.
