The lower surface is carried out in a southerly direction. The largest part of the territory is covered mainly kamojima landforms. Not only in southern and Central parts of the Park are most common fluvioglacial and glacial forms of relief surface. The formation of the relief occurred as a result of erosion, the effect of which was actively accelerated the glaciers that belongs to the so-called Valdai glaciation. The location of the Park can be described as part of the Baltic-Valdai ridges which are located on the border of the Valdai glacier. With regard to geological objects, they are especially characteristic and represent Grably is iMovie ridge, the length of which can reach up to 10-12 km and a width of 300-400 km at the height of 25-40 km.

Judging on river regime, then they all belong to the East European type, which is associated more with snow food. For all rivers especially typical overpriced spring flooding, and reduced summer low-water period.

In the Sebezhsky area of the Park is dominated by podzolic, peat-podzolic, sod-podzolic soil types, which indicates a strong ruggedness of the terrain, the soils inherent complexity. The phenomenon of erosion in the Park is not observed.

With regard to flora of the national Park, it is worth noting here that the most characteristic plant protection, although in the area of the Park protected species of flora not so rare.

In the national Park "Sebezhsky" at the moment, especially developed road, water and Hiking tourism, and developed ornithological routes and have two ecological paths.
