Marsholm is the biggest island in Lake Möckeln and is connected to the mainland with a bridge. The southern part of Marsholm, the Skälsö islands, Skallö and Sandören along with a few small islands to the east of Marsholm as well as 315 hectars of water constitutes the nature reserve known as Marsholm.
There are two walking trails on the island, one on the northern part and one on the southern part, that lead around the island through pastures, forests and along the coast.
Within the nature reserve there are natural forests of shifting character. On the main island the forest is dominated by fir while the marshes and the beach forests are mainly composed of leaf trees. These mixed forests that have an unusual amount of dead trees house rare insects and different types of woodpecker.
The bird life on the island groups to the east of the main island is susceptible to interference. As for what species reside on in the reserve, there is for example loon, osprey, heron, greylag and tern. Lake Möckeln is also known as an important resting place for goosander, swan and eagle. Between April 1 and August 1 it's forbidden to land on any island other than Marsholm and Sandören.
