Lidingö, together with the Fjäderholmarna islets south of Lidingö, and a few residential islets, forms a municipality with about 45,000 inhabitants, with a land area of 30 square kilometres.
Founded as an upper-class sanctuary in the 1910s with detached houses along the Lidingöbanan railroad (closed down until 2015), and the AGA industries, Lidingö got city privileges, and the municipality still styles itself Lidingö stad. Lidingö contains suburban areas with high-rise buildings as well as single-family houses, several embassies, conference hotels, a few farms, and a nature reserve.
Lidingö is connected to Stockholm by two parallel bridges at Ropsten, the end station of the subway in the Östermalm district. Buses carry on to Lidingö (see Stockholm#Public transport). Just as inner Stockholm, Lidingö is in the inner public transport zone.
The Stockholm congestion tax has an exception that favours Lidingö. A vehicle that passes a toll station at Ropsten, and another toll station within 30 minutes, pays no fee. This means that a car can pass from the national road system to Lidingö, or the other way around, without paying. This requires the passage takes less than 30 minutes, which cannot be guaranteed during rush hours.
Lidingö is well within reach for bicycles from central Stockholm, and has some stands for Stockholm City Bikes. 
Most of Lidingö is accessed by bus, car, walk and bicycle. Timetables for the public transport on SL.se 
You can rent the Stockholm City Bikes at three locations at Lidingö: Stadshuset, Baggeby and Torsvik.
Lidingö has a lot of nature reserves and a beautiful scenery. Lidingö was also the home of sculptor Carl Milles, humanitarian Raoul Wallenberg, and engineer Gustaf Dalén. Several other celebrities, such as German playwright Bertolt Brecht, have also lived on the island.
