Tosantos is a municipality and town located in the province of Burgos, Castile and León, Spain. According to the 2004 census (INE), the municipality has a population of 60 inhabitants. Tosantos is located on the Camino de Santiago de Compostela, a 1200-year-old pilgrimage route that runs through France and Northern Spain to the Spanish city of Santiago. The hamlet has a pilgrim hostel which is open from April through October and hosts up to 50 pilgrims a night.

800 years ago a woman, known as La Ermita, lived in a cave in the cliffs above Tosantos and ministered to the passing Pilgrims. A chapel has been built into that cave and once a year, on Fiesta day, the inhabitants of Tosantos hold a procession through the town, up the winding path to the cave and give thanks to God, Santa Maria and La Ermita for blessing the town.
