The best MTB trails around Piasecznik Wielki

interesting solution for bicycles. Although the road is paved, narrow but very useful asphalt strips have been poured on both sides

I recommend, it's great to ride on this kind of gravel

A former chalk and marl mine operated by the nearby "Stern" Portland cement factory, founded in 1862 and owned by the Toepffer family. In 1925, a sudden flood of groundwater through a layer of permeable sand led to the quarry's opening. The quarry quickly filled with water. People were immediately evacuated. The quarry was flooded. Emerald Lake was created, which owes its color and name to the high calcium carbonate content in the water and the reflection of light from the chalk bed. In good weather, railway wagons and even workers' tools can still be seen at the bottom of the lake. A concrete bridge, part of the railway track used to transport chalk output to the nearby cement plant, still stands near the lake today.

The Groński boulder is an erratic boulder: a colossus. It has been a natural monument since 1956. And who was Groński? Stanisław Groński was a Polish mountaineer and a pioneer of tourism in the Szczecin region, as you will learn from the information placed on the boulder itself. Mr. Groński died a tragic death during an expedition to Mont Blanc in 1957.

A resting place at a fork in the road. A shelter with benches, no table. Next to a ladder for exercises. Everything is old. It is close to Lake Emerald and Stones Morowe

Groński's boulder was protected as a natural monument in 1956. Previously, it was called the Aleksander Świętochowski Stone or Bolkowy Głaz, in honour of Bolesław Krzywousty. The boulder is 1235 cm in circumference, 450 cm long and about 150 cm high. It also has a hole for placing an explosive charge. In 1959, a plaque was placed on the boulder with the inscription "In memory of Stanisław Groński, a leading Polish mountaineer, a pioneer of tourism in the Szczecin Region. He died in the Mount Blanc massif in August 1957." Stanisław Groński was a very colourful character. He was passionate about the mountains, which was partly due to his origins. He was the son of a Tatra juhas. He went on many expeditions to the Alps and the Atlas Mountains in Morocco. During World War II, he supported partisans from the Polish Underground State. Later, fate brought him to Szczecin. He settled there with his family. Even though he worked for the Polish State Railways, he was completely absorbed by local studies. He became an expert and a bard of Western Pomerania. He never forgot about the mountains, and they never forgot about him. He died in 1957 while traversing Mont Blanc. The boulder bearing his name in the Bukowa Forest is not the only one. His memory was also honored with symbolic plaques in the Julian Alps, at the Tatra Symbolic Cemetery near Osterwa and at the cemetery in Chamonix.

Also known as the Klęskowo stronghold, it is located in the Bukowa Forest on the Chojna hill, 74 m above sea level. On its flattened and elongated peak, we can see an early medieval stronghold, from the 9th-12th centuries. Poorly legible, destroyed ramparts, 300 m long, surround the peak with an area of 0.75 ha, overgrown with pine and beech. According to legend, a powerful castle of robber knights stood here, attacking all travelers, mercilessly robbing them. The stronghold, cursed, and its crew sank underground.
