The terrain of Lviv Oblast is highly varied.
The southern part is occupied by the low Beskyd (ukr: Бескиди) mountain chains running parallel to each other from northwest to southeast and covered with secondary coniferous forests as part of the Eastern Carpathians; the highest point is Pikuy (1408 m).
North from there are the wide upper Dniester river valley and much smaller upper San River valley.
These rivers have flat bottoms covered with alluvial deposits, and are susceptible to floods.
Between these valleys and Beskyd lies the Precarpathian upland covered with deciduous forests, with well-known mineral spa resorts (see Truskavets, Morshyn).
It's also the area of one of the earliest industrial petroleum and gas extraction.
These deposits are all but depleted by now.

In the central part of the region lie Roztocze, Opillia, and part of the Podolia uplands.
Rich sulphur deposits were mined here during the Soviet era.
Roztocze is densely forested, while Opillia and Podolia (being covered with loess on which fertile soils develop) are densely populated and mostly covered by arable land.
In the central-north part of the region lies the Small Polesia lowland, geographically isolated from the rest of Polesia but with similar terrain and landscapes (flat plains with sandy fluvioglacial deposits and pine forests).
The far North of the region lies on the Volhynia upland, which is also covered with loess; coal is mined in this area.
