Take a nice walk through the forests of Malé Karpaty to the ruins of a lookout castle. It is an ideal place for picnic or barbeque. On foot or terrain bike from Stupava Park (1 h, 20 m) or from the church in Borinka.
From the top there are spectacular views of the Little Carpathians and the southern part of Záhorská lowlands. In good weather you can see the Austrian Alps. Very interesting are the waterspouts - dragon heads. One has fallen down at the gate. The ruin is quite preserved. You can read about Pajstun on the plagues before the castle and in Borinka.
