The Camino Catalán from Monestir de Montserrat to Puente la Reina spans Mediterranean hills, open Aragonese valleys, and the greener approach into Navarre, producing a broad mix of sun, showers, wind, and cloud. April and September align with milder patterns described for spring and early autumn along this route. Expect variability between regions and weeks: brighter spells leaving Catalonia, exposed and breezy stretches across Aragon, and cooler, wetter phases toward Navarre as seasons shift.
