The Camino del Salvador crosses from the dry plateau of León into the greener, rain‑washed hills of Asturias, including a meaningful mountain pass. Balancing heat on the León side with showers and cloud in Asturias, many walkers choose April, May, and September for cooler temperatures and longer daylight. Outside these windows, conditions swing from hot, exposed stretches and afternoon storms in midsummer to colder, wetter, and occasionally snowy spells through winter, with shorter days.
