Cathedral Caves are a series of dramatic sea-carved caverns and rock formations along the wild North East Tasmanian coastline. High sandstone cliffs, collapsed overhangs, and tunnel-like passages create a cathedral-like ambiance with light filtering through openings. The surrounding waters offer clear snorkeling over mixed boulders and sand patches, with kelp forests and diverse temperate reef life visible on calm days.
