La Pedrera (Casa Milà)

Worth it if you're into Gaudí's architectural vision and don't mind paying for entry—55,000+ reviews at 4.7 stars suggests it genuinely impresses people. The sheer number of experiences available (261 on Viator alone) means you can tailor your visit, though going early or booking a timed slot will save you from the inevitable queues that come with that kind of popularity.
