Joel's new campground is ready for you this season.  It has a community kitchen, bathrooms, and great camping spots.  It's directly across from La Palma climbing area.  You could almost belay from your tent.  This campground has some of the best wifi around.  Joel has been developing steep cave routes throughout the Nuevo Leon area for the last decade.  He is one the warmest most welcoming climbers you will meet.  Contact him through his Facebook page here: https://www.facebook.com/ELSALTOCRAGGROUND
