Areias do Seixo

A nightly communal bonfire on a wild stretch of Atlantic coast north of Lisbon sets the tone at this fourteen-room eco-resort, where the architecture looks like the dunes grew it: salt-bleached timber bedposts, polished stone, and glass walls that make the outside feel optional. The organic farm and greenhouse feed the restaurant; mussels come from foraging trips with staff. It holds a Michelin Key.
