About Rummu Quarry
Rummu Quarry is Estonia's best-known inland quarry dive, centered on the underwater prison, mine remnants, and other concrete ruins in a broad basin. The route threads between walls, machinery, and lake floor features rather than following a single drop. Book ahead and plan for managed access, with visibility that can swing from murky to very clear.
