Gyllebosjön is one of the few lakes in the East. It is scenic in the hilly forest landscape of southeastern Skåne surrounded by ancient woodland forests and nature pastures. Gyllebosjön is part of a Natura 2000 area, and in 2009 Gyllebo formed a nature reserve that covers the lake and its surrounding areas. Gyllebosjön is the largest lake in Österlen. It is a deep spring lake with relatively clear water and a rich fish fauna.
The lake has many natural fish species; like pike, perch, suther, ruda, braxen, gossip, roach. In addition, gossip has been implanted during the 2000s.
There are also many flowering and underwater plants in the lake, including yellow water lily, horns and trubbnate. Along the seabed is the "Munkaryggen", a pillar of stone.
Gyllebosjöns fiskevård har anor från slutet av 1950-talet. Föreningens syfte är att främja fisket i Gyllebosjön.
