Rummu Quarry Lake

Rummu Quarry Lake is a flooded limestone quarry near Vasalemma in Lääne-Harju Parish, Harju County, Estonia, about 45 km southwest of Tallinn. It is not a beach in the strict sense, but it is one of the county's best-known swimming spots. The water is famously turquoise and very clear, a result of the limestone bottom, and it is notably cool and deep in places. Instead of sand, the shore is formed of rocky and gravelly edges, quarry walls and spoil heaps, with some small sandy patches. The quarry was worked for limestone and is next to the former Murru prison, and as the pumps stopped the pit flooded, leaving submerged structures, including remnants of old buildings and equipment, visible beneath the surface. This makes it a popular site for diving, snorkelling and photography, and a diving school operates nearby. The lake is sheltered from sea wind by the surrounding quarry slopes, so the surface is usually calm. The atmosphere is adventurous and sociable, drawing swimmers, divers, photographers and families; weekends in summer can be busy. Facilities include parking, toilets and seasonal kiosks, though services are modest and the site is largely unsupervised, so visitors should swim with care, watch for depth changes and avoid unstable edges. Access is by car in about 45 minutes from Tallinn, with parking near the lake. Buses run toward Vasalemma, but a walk is then needed, and the schedule should be verified. Water shoes are strongly recommended because of the rocky entry. The landscape includes dramatic limestone cliffs and the dead trees emerging from the water, giving striking photographs, particularly at sunrise or in soft evening light. Visitors should respect signs and restricted areas near the former prison grounds.
