Kolín – letiště, Natural monument near Pašinka, Czech Republic.

Kolín – letiště is a natural monument formed by the grass airfield of Kolín's long-used domestic airport, northwest of Pašinka in the Kolín district. Its 22.74 hectares lie at 268–273 m and are mown and trodden by aircraft movement; perennial ryegrass dominates the turf.

The site gained official protection status in 2012 when it was designated as a natural monument. This recognition reflected efforts to safeguard the area's ecological diversity for future generations.

The name of the natural monument comes from the Kolín airport whose grass surface it protects; the airfield has been in long-term domestic use. The ground squirrel population has been known since the late 1970s and has been monitored since 2003. The site overlaps partly with a Natura 2000 site of the same name.

The natural monument lies east of road II/125 between Kolín and Kbílek, northwest of Pašinka. It is the grass airfield of a working domestic airport, so watch for aircraft movements and keep to the edges; the ground squirrel population is concentrated in the northern part.

The airport's mown grass is dominated by perennial ryegrass, and the ground squirrel population lives mainly in the northern part of the strip, where the airfield surface lets it grow. The site overlaps partly with a Natura 2000 site of the same name.
