Among unusual beaches - both best approached from Ciudadela - are Cala Morell and Algaiarens.  Algaiarens is a twin beach approached through a fertile pine-clad valley known as La Vall, and also has a lagoon.
The northern coast has two further unique features. If one follows the sign-post marked Port Addaya on the road to Arenal d' en Castell, one is suddenly amid scenery of the Scottish western Highlands: a long narrow inlet of the sea like a sea loch sheltered by low hills on each side. In October or November these slopes will be covered by heather. Addaya is 3.5km long, with several islets and the small fishing hamlet of Na Macaret at its mouth. This idyllic and lonely spot was the main disembarkation point of the last British expedition against the island in 1798, under General Sir Charles Stuart.

The second is the island's least-known feature: its beautiful lake, Albufera. More than a mile long, it lies hidden by low hills to the west of the fishing village of Es Grau, only 6.8km from Port Mahon. The pleasant lagoon which adjoins the road on approaching the village is the lake's outlet by means of a sandbar on the nearby beach. The lake has an islet, and a background of hills to the west.
Albufera abounds in wild duck and other game. In the eighteenth century it was a favourite goal for the shooting and fishing expeditions of the British garrison, and we read of it as 'abounding in red mullets, and harbouring in winter an amazing variety of wild fowl'. It is now a nature reserve and bird sanctuary. Of his excursions to Albufera Armstrong wrote: 'one undergoes more hardship and fatigue in a day's shooting, which we call a diversion, than in three weeks of the strictest duty an officer is put to'.
