Dive sites in Estonia

The Pakri Peninsula area contains a diverse collection of wrecks spanning from the early 20th century through the Cold War period. Notable sites include WWII-era German and Soviet transport vessels, a scuttled Soviet minesweeper, and several merchant ships that foundered on the shallow limestone reefs. Some wrecks are in relatively shallow water at 10 to 15 metres, making them accessible to intermediate divers, while deeper sites at 25 to 30 metres offer more challenging penetration opportunities. The Estonian Maritime Museum maintains records of documented wrecks, and some are protected heritage sites.

Paldiski is approximately 50 kilometres west of Tallinn, about a 45-minute drive or a one-hour train ride on the Elron commuter rail service. Several Estonian dive operators based in Tallinn run regular trips to Pakri Peninsula wreck sites during the summer season. The harbour at Paldiski provides sheltered boat launching, and most wreck sites are within 15 to 30 minutes by boat from the harbour. Accommodation options in Paldiski are limited, so most visiting divers base themselves in Tallinn.

Recreational diving at most Pakri Peninsula sites does not require a permit, but certain wrecks are classified as protected underwater cultural heritage by the Estonian government, and diving on those requires prior notification to the National Heritage Board. Your dive operator will know which sites have restrictions. The former Soviet military infrastructure on shore is largely abandoned but some areas remain restricted. All divers should carry a surface marker buoy as there is occasional commercial shipping traffic in the area.

Rummu Quarry was a limestone quarry operated by prisoners from the adjacent Rummu Soviet prison camp during the Soviet occupation of Estonia. After the Soviet Union collapsed and the prison closed in the early 1990s, the pumps that kept the quarry dry were shut off, and groundwater gradually flooded the site. The rising water submerged the prison buildings, guard structures, and industrial equipment, creating the unique underwater landscape visible today.

Yes, Rummu is excellent for beginners and newly certified divers. The maximum depth is around 15 meters, there are no currents, and entry is easy from the shore via a gentle slope into the water. Visibility is generally good, especially in early summer. The submerged structures begin at very shallow depths, so even snorkelers can appreciate the ruins. That said, water temperatures require appropriate thermal protection, and a drysuit is recommended outside of peak summer months.
