The Ostrężnik Castle was completely destroyed, and more precise information about it is missing. The castle is located in the forest on a hill and borders a rock, with which it was connected by passages. The mysterious and rather gloomy ruin of the fortress, probably dating from the 14th century, is one of the least known defensive structures of the Kraków-Częstochowa Upland. The outlines of the walls are preserved in very poor condition. The layout of the castle, divided into upper, lower, and outer bailey, is also barely recognizable today.

The Coral Cave is one of the most interesting caves located in the Sokole Góry nature reserve, located near Olsztyn in the Kraków-Częstochowa Upland. Located on the southern slope of Pustelnica Mountain, it was accidentally discovered in the years 1918-1939 by spar seekers. Its length is about 375 meters, and the height difference reaches 35.5 meters. The name of the cave comes from the unique dripstones resembling corals, which form on the roots of trees penetrating the interior of the cave. Due to the difficult conditions and the need to protect dripstones, the cave is not open to free exploration; exploration requires specialist equipment and speleological experience.
