Very beautiful, but be careful: paths can flood at high tide. You'll then have to stand in knee-deep water for a few meters with your bike.

The Palheiros da Costa Nova, or the colorful little houses of Costa Nova, are the old fishermen's warehouses. In other words, these are where they stored their nets, boats, and fishing gear at the end of the day. But what makes the palheiros da Costa Nova so special, and why everyone wants to see them, is their picturesque and colorful appearance. The striped facades leave no one indifferent. And the fact that they are located in a seaside setting attracts even more visitors. Besides the palheiros, Costa Nova offers other must-see attractions for visitors. We're talking about extensive golden sand beaches, ideal for sunbathing or enjoying water sports like surfing and windsurfing. (Source: loveitportugal.com)
