Zerkalnoe, Freshwater lake and recreational protected area in Kavalerovsky District, Primorsky Krai, Russia

Zerkalnoe is a freshwater lake in the Kavalerovsky District of Primorsky Krai, lying in the valley of the Zerkalnaya River near the village of Zerkalnoye. It measures about 1.5 km long and 0.9 km wide, with an area of 0.99 km² and a shoreline of 2.9 km. It is the only large lake in the mountainous district, fed by the 13 km Pad Ovsyannikova River and several small streams, and linked to the river by a channel.

In 1993 the Primorsky Krai administration designated Lake Zerkalnoye a specially protected natural area for recreation (decree No. 470 of 17 December 1993). A rest base of the Khrustalnensky mining and processing combine was built on its shore. The lake lies in the Zerkalnaya River valley, connected to the river by a channel.

The Russian name Zerkalnoye means "mirror", after the lake's flat surface. On the banks of the channel linking the lake to the river stand beekeeping farms, and a reinforced-concrete bridge carries the road across it toward Zerkalnaya Bay. The lake lies beside the village of Zerkalnoye in Kavalerovsky District.

Reaching the lake requires traveling through rural roads in Kavalerovsky District, with some sections needing careful driving due to limited infrastructure. Plan your visit during drier months when road access is more reliable, and check local conditions beforehand.

The lake is the only large lake in the mountainous Kavalerovsky District, which is why the Khrystalnensky mining and processing combine built its "Zerkalnaya" holiday base on its shore. A reinforced-concrete bridge crosses the channel linking the lake to the Zerkalnaya River, and apiaries stand along the channel banks.
