Oszast, also called Oszusem or Oszustem, is a distinctive peak with a height of 1155 m above sea level. It lies in the mountain ridge that connects the massif of Wielka Rycerzowa with the area around the peak of Krawców Wierchów. The summit belongs to the Raczański range. In the remote area of Oszast, through which the Polish-Slovak border runs, there is an interesting patch of the primeval forest, which is a nature reserve. Over the top a Slovak trail leads along the border.
