The area of the National Park Schinia has flat character. The terrain slope is small, 0-2% and only the bare sandy coastline presents a steeper slope to the sea. This area of the forest appears smoother in the eastern section, which for the most part is almost flat and interrupted by bouts of low dunes limited to about one meter. Unlike in the western part of the forest, especially to the beach exacerbations become more frequent and larger amounts. The observed difference between the two sections is mainly linked to the fact that the eastern part protects from the wind, the longitudinal extension of Cynosure-Mitika plus the department receives more strongly Leveling human presence.

Apart from bouts of dunes, the area of forest is also interrupted by the beds of some old small currents which tend to gradually disappear as the action was stopped by the road construction along the entire north side and the opening of the drainage ditches on both sides the forest. North and east of the pine forest are lower positions are inundated with water and create the once Great State of Marathon. Today a large part of this area with drainage and embankments, which were converted into agricultural land area and summer house while another part is occupied by the Rowing some telecommunications installations. The marshy area was left shattered by a network of roads and a network of channels which results in two drainage pipes on either side of the forest to the sea. The marsh is flooded in the winter than in the summer when water almost dried, especially the extremely dry and hot season.

East of the forest and the marsh rises oblong hilly limestone formation Mitika ending in Cape Cynosure fairly steep slopes.

The area developed two types of distinct aquifers: the karstic and alluvial plain of the section. The karstic aquifer is not uniform and separated in the western part, ie Makara source and east, ie hills Drakonera. At the western end of the front jet blessed water source is more burdened with chloride in relation to the eastern. The karstic aquifer blessed source has much better quality than the alluvial aquifer.

The catchment area is 35,6 Km2. The average slope is calculated at approximately 7.0% and the rate of infiltration in 35-40%. The main part of the amount of water discharged infiltrates through Makara Source.

The coastal zone Schinia, occupied by the forest, width 450 m., Which falls slightly to the west, consists of sandy formations thinogeneis Quaternary - Holocene.

Then to the north, the marsh includes deposits from ilyopilodi and argillaceous materials of varying thickness deposited on sandy formations of the same geological period as above.

At the east end of the hilly formation Mitika formed of hard limestones (marbles) of the upper Cretaceous, with side scree and scree cones in small places.

Based on the geological medium discern at first level three categories ie land soils in alluvial deposits and saline sites (site member) and soils on hard limestone.
