Pena National Palace (Palacio Nacional da Pena)

Worth it if you're after a proper wow-factor palace with near-universal approval – 67k reviews at 4.9 stars is genuinely rare. Best value going as part of a guided tour (most Viator options are £25–50) rather than solo entry, since context makes the architecture land harder; if crowds are your enemy, aim for early doors or shoulder season, because this many happy visitors means it gets rammed.
