Pribaikalsky National Park (also spelled Pribaykalski, Russian: Прибайкальский национальный парк) covers the southwest coast of Lake Baikal in southeastern Siberia.

The park is managed with three other nature reserves, and is a major component of the UNESCO World Heritage Site "Lake Baikal".

The water of the lake itself is characterized by oxygen saturation over 70% (even at maximum depths), high levels of clarity, and low calcium.

[4] The climate of Pribaikalsky is moderate continental (Köppen climate classification Dwb), characterized by four distinct seasons, high variance between winter and summer temperatures, long dry winters, and short, warm and rainy summers.

[7] The slopes of the mountains facing Lake Baikal are forested with steppe pine and larch.

The wetter tops of the mountains are Siberian pine-fir, and in the valleys the tree cover is typically spruce, larch, alder, aspen, and birch.

[10] Pribiakalsky National Park and Baikal-Lensky Nature Reserve ('Zapovednik') were created in 1986, and were placed under common management of "FGBU Zapovednoe Baikal".

Pribaikalsky receives the majority of tourists, foreign and domestic, due to Lake Baikal (over 400,000 per year overall).

The need to balance the recreational load with the conservation of nature is a large part of the park's mission.

The 'Great Baikal Trail' runs along the west coast of the lake through Pribaikalsky; during the winter, the trail loop is open for skates, skis, and snowmobiles for tourists to view the ice formations.
