How The Month Feels
March gives Santiago de Compostela a damp, inward-facing pace, with the stone around the cathedral turning the city into a museum walk between showers. In the museum quarter, Museo do Pobo Galego and Centro Galego de Arte Contemporánea feel especially useful as the day shifts.
What To Lock In Early
Reserve the Catedral de Santiago de Compostela and the Museo Centro Gaiás first, because those are the visits most likely to shape the day. Leave Pazo de San Lourenzo de Trasouto and Colexiata de Santa María a Real de Sar for the clearest weather window.
How to do it
