The small Hebridean island of Eigg is an enchanting mix: beautiful scenery, a surprising variety of rocks, and a friendly and innovative local community. There are many geological riches to explore, including important fossil-rich sedimentary rocks and the singing sands, fringed by sandstone cliffs cut by basalt dykes. The famous Sgùrr forms the high point of the island.
Eigg is mostly formed from basalt lava flows and intrusions, the remains of extensive volcanic activity 60 million years ago. These are underlain by sedimentary rocks from the Jurassic Period. The rocks of An Sgùrr were formed by a final, violent volcanic eruption, the last known volcanic activity in this area.
This trip will explore Eigg’s geological variety, including the west coast, the south of the island and An Sgùrr.
