Felix Mendelssohn, who visited the uninhabited island of Staffa, off Mull, in 1829, was inspired to compose his 'Hebrides Overture' after hearing waves echoing in the impressive and cathedral-like Fingal’s Cave. The cave walls and surrounding cliffs are composed of vertical, hexagonal basalt columns that look like pillars (Staffa is Norse for ‘pillar island’). You can land on the island and walk into the cave via a causeway. Nearby Boat Cave can be seen from the causeway, but you can’t reach it on foot. Staffa also has a sizeable puffin colony, north of the landing place.
Northwest of Staffa lies a chain of uninhabited islands called the Treshnish Isles. The two main islands are the curiously shaped Dutchman’s Cap and Lunga. You can land on Lunga, walk to the top of the hill, and visit the shag, puffin and guillemot colonies on the west coast at Harp Rock.
