A couple of the scenic highlights in Corsica not listed under their own sections include:
Isles Sanguinaires
One of the more common boat trips from Ajaccio, the Isles Sanguinaires (together forming the Archipelago of the sanguinaires) are about 15km from the town by boat but only just off the headland at Pointe de la Parata. The tour takes a few hours but is well worth the trouble.
Best visited at sunset to see them at their most photogenic, the islands are a designated reserve for sea birds and other wildlife and have a fascinating and diverse habitat with many plant species not found on the Corsican mainland.
There is a lookout tower dating from 1608 and the Genoese occupation of Corsica towards the southern end of the archipelago.
Aiguilles de Bavella

Following the Col de bavella between Sartene and across Corsica towards the east, there is a dramatic landscape of rocky needles (aiguilles), spires and cliffs along the horizon, with trees stunted by the weather and difficult conditions.
You can also see the Trou de la Bombe, a large hole through a cliff, along the route, and a statue known as 'Notre-Dame des Neiges'.
Start exploring at Conca, Quenza or Zonza.
Desert des Agriates

In the Balagne region of Corsica, the desert des Agriates is the only 'official' desert in Europe. The Desert des Agriates is a barren, wild and beautiful wilderness based west of Saint-Florent, along the coast and around Mont Genova.
At 40 km long, it is also the longest stretch of protected coastline in Europe. There is a coastal path that runs the length of the coast in the desert des Agriates from Ostriconi to Saint Florent - come prepared if you intend to do it, it will take 2 days minimum.
There is only one road that crosses the desert - the D81 from Saint-Florent to the Ostriconi Valley. The beaches, of which there are several with beautiful fine sand, are accessible from the D81 or by boat from Saint-Florent. Two in particular, close to Saint-Florent, are the Plage de Loto and the Plage de Saleccia
