Highlands dominate the territory of the krai. Most of the territory is mountainous, and almost 80% of it is forested. The average elevation is about {{convert|500.|m|sp=us}}. [[Sikhote-Alin]] is a mountainous formation, extending for the most part of the Krai. It consists of a number of parallel ranges: the Partizansky (Partisan), the Siny (Blue), the Kholodny (Cold), and others. There are many [[karst]] caves in the south of Primorye, including the relatively accessible Spyashchaya Krasavitsa cave (the Sleeping Beauty) in the Ussuriysky Nature Preserve. There are comparatively well-preserved fragments of ancient volcanoes in the area.

The ranges are cut by the picturesque narrow and deep valleys of the rivers and by large brooks, such as the [[Partizanskaya River|Partizanskaya]], the [[Kiyevka River|Kiyevka]], the Zerkalnaya, the Cheryomukhovaya, the Yedinka, the [[Samarga River|Samarga]], the [[Bikin River|Bikin]], and the [[Bolshaya Ussurka River|Bolshaya Ussurka]]. Most rivers in the [[Krai]] have rocky bottoms and limpid water. The largest among them is the [[Ussuri River|Ussuri]], with a length of {{convert|903|km|sp=us}}. The head of the [[Ussuri River]] originates {{convert|20|km|sp=us}} east of Oblachnaya Mountain. The vast Khanka Lowlands extend into the west and southwest of Primorye, carpeted by coniferous-deciduous forest. A part of the Lowland surrounding the largest lake in the [[Russian Far East]], [[Khanka Lake]], is occupied by a forest-steppe.
