In the eastern part of the municipal territory there is the source of the stream Kateřinský potok, the headwater of the Pfreimd River.

The first written mention of Lesná is from 1348, when the king sold the village with the church to Arkleb of Tisová.

From 1523, it was located on a trade route from the Kingdom of Bohemia to the Bavarian Upper Palatinate region, which brought prosperity to the village.

Several settlements immediately at the frontier with West Germany, including Zahájí, were abandoned and became a restricted zone after the implementation of the Iron Curtain.
