11Sintra, Portugal

With moss-covered forests, misty palaces, and whimsical architecture, Sintra looks like something conjured by a fantasy author.

While day-trippers visit from Lisbon, staying overnight lets you enjoy the magical palaces and gardens in peace. Explore the colorful Pena Palace, the mysterious Quinta da Regaleira, and the peaceful hilltop Moorish castle without the midday crowds.
