We had six days of hiking with Lautaro in the San Pedro de Atacama area, including hiking up Lascar volcano. We highly recommend him. He is very knowledgeable and takes time to explain you things. He is careful but at the same time pushes you a bit to do things he understood you can handle. Last, but not least, prepares good breakfast and has good music in his 4×4 car (like imagine dragons, daft punk, etc). Well done!
