Rocha dos Bordões, with its vertical striations, is one of the most iconic natural landmarks on Flores Island in the Azores. This unique geological formation consists of massive, vertical basalt columns that resemble a giant organ or a series of stacked pillars. The columns were formed by the slow cooling of volcanic lava, which caused the rock to contract and crack into these striking hexagonal shapes.

The formation is particularly impressive when viewed in different lighting conditions, especially at sunrise or sunset, when the play of light and shadows enhances the texture and depth of the columns.

While you can't get up close to it, the view from the roadside viewpoint is definitely worth a stop for a quick photo. Just pull over, snap a pic, and marvel at this unique twist of nature along your drive.
