Dive-site story
Set within the historic Dinorwic slate workings in Llanberis, Vivian Quarry offers sheltered inland diving surrounded by sheer slate cliffs. Divers navigate among submerged industrial relics including miners' carts, rail tracks, quarry buildings, and suspended training platforms. The enclosed setting ensures calm conditions year-round, making it a staple for skill development and drysuit practice.
