The Müggelturm (“Müggel Tower”) is a popular day-trip destination in Köpenick, in southeastern Berlin, Germany. It is located to the south of the Müggelsee lake in the Müggelberg hills atop the Kleiner Müggelberg (“Small Müggelhill”). Berlin's highest natural elevation is the nearby Großer Müggelberg at 115 m.

The Müggelberge (also formerly called the Müggelsberge) are a wooded line of hills with heights up to 114.7 m above sea level (NHN) in the southeast of Berlin's Treptow-Köpenick quarter. They are dominated by the Kleiner Müggelberg (88.3 m) and Großer Müggelberg (114.7 m). The Müggelberge cover an area of around seven square kilometres. The ridge was formed during the ice age. A viewing tower called the Müggelturm has been erected on the hills with a view of the Müggelsee and the Berlin-Müggelberge TV Tower.

The Berlin-Müggelberge TV tower is the 31 metre tall base of a tower, never completed, in the Müggel hills of southeast Berlin, Germany. The tower base is currently used as radio relay link station. The tower was originally planned as the TV tower for Berlin. It was to have a total height of 425 feet (130 meters) with an observation platform at 230 feet (70 meters). After construction was started in 1954, a survey indicated that the tower would endanger aircraft on approach to the Berlin-Schoenefeld airport. For this reason, on 13 December 1955 construction was stopped. The tower base was later used by the East German Ministry for State Security (Ministerium für Staatssicherheit or Stasi) as a listening post. Today it serves the Deutsche Telekom AG as radio relay link station and has a radar dome on its top. Close to the tower, there is a 64 metre tall lattice tower with aerials for non-public mobile radio services and directional antennas. The Berlin-Müggelberge TV tower is not accessible to the public and is not to be confused with the Berlin-Müggelberge look-out, known as the Müggelturm (Müggel tower), which is publicly accessible.

Müggelheim (German pronunciation: [ˈmʏɡl̩ˌhaɪ̯m] (listen)) is a German locality (Ortsteil) within the Berlin borough (Bezirk) of Treptow-Köpenick. Until 2001 it was part of the former borough of Köpenick.

The Müggelsee (German pronunciation: [ˈmʏɡl̩ˌzeː] (listen)), also known as the Großer Müggelsee, is a natural lake in the eastern suburbs of Berlin, the capital city of Germany. It is the largest of the Berlin lakes by area, with an area of 7.4 square kilometres (2.9 sq mi), a length of 4.3 kilometres (2.7 mi) The lake is in the Berlin district of Treptow-Köpenick. The suburbs of Köpenick, Friedrichshagen, Rahnsdorf and a little section of Müggelheim border on the lake. The lake itself is 8 metres (26 ft) deep at its deepest point. At its south end are hills called the 'Müggelberge', which are 115 metres (377 ft) high; they were formed during the Pleistocene (as a kettle hole, remaining at Weichselian glaciation). On the so-called 'Kleiner Müggelberg', the much-visited and popular 'Müggelturm' (a tower) was built, the first one in 1889 (destroyed in a fire in 1958), and the current one in 1960/61. The tower offers extensive views over the lake and the forests against the Berlin skyline.The River Spree flows into the lake via the smaller Kleiner Müggelsee, which is only 0.16 square kilometres (0.062 sq mi) in area. The Friedrichshagen waterworks on the northern bank of the Müggelsee obtains most of its water from the lake. There are also numerous deep wells located near the banks, and are mainly fed by the bank filtrate and only to a small share by groundwater.

The Zeuthener See (German pronunciation ) is a lake situated to the south-east of Berlin, the capital city of Germany, in the states of Berlin and Brandenburg. At an elevation of 34 metres (112 ft), its surface area is 2.33 square kilometres (0.90 sq mi).

The Erpe is a tributary of Spree River in Brandenburg and Berlin, Germany. The upper third is also known als Langes Elsenfließ ("Long Lizzy-Flow"), the lower two thirds for about half a century were noted as Neuenhagener Mühlenfließ. Previously they had been one of several Mühlenfließe ("Mill Flow"s) without a specification. The course itself is quite natural, but it suffers pollution from a purification plant.

The Oder–Spree Canal (German: Oder-Spree-Kanal pronounced [ˌoːdɐˈʃpʁeː.kaˌnaːl] (listen)), is a canal in the east of Germany. It links the Dahme river, at Schmöckwitz in the south-eastern suburbs of Berlin, with the River Oder, at Eisenhüttenstadt. It provides an important commercial navigable connection between Berlin and the Oder, and hence Poland.The canal has several connections to the River Spree. For a stretch of about 20 kilometres (12 mi) near Fürstenwalde the canal utilises the river as part of its route, and there is a navigable connection to the river upstream of this section, although these reaches are relatively shallow and are generally only used by leisure craft. However the principal connection is via the River Dahme, which joins the River Spree at Köpenick, to the east of the centre of Berlin.
