💡 Good to know
- The Estrela road to mainland Portugal's summit runs clear, Coimbra's students serenade the end of term in May, and the schist villages glow in low autumn light.
- Serra da Estrela takes Portugal's only real snow — the tower road can close — while Aveiro's canals and Coimbra's library stay comfortable all winter.
