Grytö is located close to land in the southeastern part of the lake Åsnen. The nature reserve also includes water areas in the lake, the two islands Helgaholm and Grönön, and a number of other smaller islets. Rich birdlife in the area.
From Lunnabacken you can look out over large areas of the Grytö nature reserve. The woodland on the islands must be developed in a way that promotes biological diversity. Because of the birds, there is no admittance to Grytö between 1 April and 31 July.
