How to do it

A few things worth planning ahead

01

Plan cue

Use May for a mix of landmark visits and museum time rather than only outdoor sightseeing.

02

Plan cue

Build your plans around the Catedral de Santiago de Compostela, the Colexiata de Santa María a Real de Sar, and Pazo de San Lourenzo de Trasouto.

03

Plan cue

Keep the Museo do Pobo Galego, Centro Galego de Arte Contemporánea, and Museo Centro Gaiás on standby for wetter hours.

Practical trip tips

Dress in layers you can take on and off easily, because the city will usually feel different in the morning and after sunset.
Keep one museum or covered landmark in reserve each day so a sudden weather shift does not ruin the plan.
Leave some breathing room in the itinerary, because this is a good month to follow the mood of the city rather than rushing it.
