The mass of intriguing red rock formations along the coastal road between Porto and Piana are known as Les Calanques, and are a highlight on a visit to Corsica. The narrow, twisting road reveals a landscape of spectacular vistas and panoramas that outdo each other at every turn, where wind and sea have eroded the pink granite rock into pillars, huge boulders and weird shapes. The scenery is most spectacular at sunset, when the setting sun highlights the natural red and pink colours of the rock, and the drive is best appreciated in the direction from Piana to Porto. The landscape is unlike any other and is truly a pleasure to drive through. Visitors can also explore the rock formations on boats or kayaks - the turquoise water contrasts spectacularly with the red rock. There are some great swimming spots hiding among the rock formations. Probably the best way to explore the landscape, however, is on foot, and there are numerous dramatic walking trails winding along the cliffs and through the forests of the area. Needless to say, one can get some fabulous photographs and find special spots; look out for the heart-shaped hole, you'll know it if you see it.
