Diogo’s tour guide from Odyssey Tours of Sintra, Pena Palace, Regaleira and Cascais felt like a marathon through a fairytale with snacks missing. Sintra is basically “stairs disguised as romance,” but somehow worth every breathless step. Pena Palace looks like a king told a LEGO set to “go wild” with colours and views. Quinta da Regaleira is where you half expect a wizard to ask for directions out of a secret tunnel. Then Cascais arrives like a reward level: ocean breeze, chill streets, and suddenly your legs forgive Diogo again.
