It consists of the eastern half of the municipality, containing the Tyresö Strand and Raksta areas, the long Brevik peninsula, and the vast forest in the south.
The Tyresö Strand area has since mid-1990s been built with a higher density with tightly packed detached, semi-detached and terraced houses.
There is a small amount of apartment buildings and commercial establishments around Strandtorget.
The forest in south contains about half of Tyresta National Park on the Tyresö side.
Located on the Brevik peninsula, southeast of Trinntorp, is Telegrafberget 84 m (276 ft) above sea level, from where one has a view all the way to central Stockholm.
