Rezerwat Puszcza Słupecka. The reserve was established to preserve, for scientific and educational purposes, diverse forest communities: alluvial forests, oak-hornbeam forests, and pine forests with rich occurrences of protected, rare, and endangered plants. The reserve itself is not open to visitors, but the old railway line to the peat mine runs along its edges (on the embankment).

The "KOC I" airdrop site was a key airdrop site for the Home Army during World War II, operating as part of the County Trail of Fighting Poland. On the night of September 14-15, 1943, air operation "Neon 6" was carried out here, during which three Cichociemni (Silent Unseen) and supplies for the Home Army, including weapons, materials, and money, were dropped. Over 100 underground soldiers participated in securing the airdrop site. The next operation – "Weller 1" – took place on the night of April 9-10, 1944. Four Cichociemni (Silent Unseen) parachuted into occupied Poland, and an aircraft delivered additional containers and parcels of supplies. The airdrops were made possible thanks to the cooperation of Home Army soldiers, Cichociemni (Silent Unseen), and RAF aircrews. The "KOC I" airdrop site played a significant role in supplying and strengthening the Polish independence underground in Masovia. Today, this place commemorates the heroes of the fight for freedom and reminds us of the underground activities of the Polish Underground State.
