Kulho island is located between Hirvensalo and Kakskerta, on the western side of Lemunaukko. The large rock rises, the field in the middle of the island, and the largest continuous reed bed in Turku that divides the island in half command the landscape of the island. Most of Kulho island has been added to Natura 2000 network of conservation areas.

The area has a rich birdlife with numerous nesting species. In addition to grove bird species and a strong woodpecker population, the rare marsh harrier (Circus aeruginosus) sometimes chooses the area as its habitat.  Some rare plant species, such as the little mouse-ear chickweed (Cerastium semidecandrum) and the spring speedwell (Veronica verna) can also be found from the small dry hillside meadows of Kulho.
