6Sintra, Portugal

A short drive from Lisbon, Sintra is a town of magical palaces, romantic gardens, and misty hills. The town has been a favorite retreat for Portuguese royalty, and its landscape is dotted with grand estates and ornate palaces. The most famous of these is the Pena Palace, a whimsical, brightly colored structure that sits atop a hill, offering breathtaking views of the surrounding countryside. The town itself is equally charming, with narrow streets, local crafts, and cozy cafes.
