Penha Longa Resort
Hidden among the rolling green hills of the Parque Natural de Sintra-Cascais, this dreamy resort has breathtaking views of the surrounding forest and the gorgeous grounds. Along with indoor and outdoor pools and a championship golf course, the resort's luxurious spa offers a private garden with thermal-regulated pools and a cascading waterfall. The resort has eight places to dine—including the restaurants LAB by Sergi Arola and Midori by Pedro Almeida, both holding Michelin stars—that consistently win awards for their cuisine.
