About this tour
A two-hour geological tour of Ustica island reveals the volcanic forces that shaped this Mediterranean landscape. Your guide takes you to the dramatic spreader zone near Punta Cavazzi lighthouse, where magnetic anomalies, sea caves, columnar basalt formations, and a world-renowned fault line tell the story of ancient eruptions. Black cliffs frame turquoise waters as you explore rocks with unusual luminescent properties and learn why compasses behave erratically here.
Highlights
- Magnetic rocks that disrupt compass readings
- Sea cave carved through solid stone
- Basaltic columns rising from re-emerged beach
- Internationally studied geological fault line
- Luminescent rock formations in coastal setting
- Punta Cavazzi lighthouse and spreader zone views
What to expect
Expect a straightforward walking exploration of exposed geological features rather than a technical deep-dive. Your guide points out distinct rock formations and explains how volcanic activity and tectonic movement created the island's unusual character. You'll handle specimens and test compass behaviour at magnetic hotspots. The pace is gentle across accessible coastal terrain, with the Tyrrhenian Sea providing constant scenery. Two hours allows time to linger at key formations without feeling rushed.
