A great-value budget option with simple six- and eight-bed dorm rooms in a converted house a few blocks northeast of the main plaza. There's a shared kitchen, convivial English-speaking hosts and a festive outdoor restaurant (mains around M$90) down below. Also offers tours (in a blue VW bus!) from around M$650 per person to the main sites in the Cuatrociénegas Nature Reserve.
