Villages of Bližší Lhota, Hodňov, Hory, Hůrka, Olšina, Pernek and Žlábek are administrative parts of Horní Planá.
Horní Planá is situated in the Bohemian Forest on the southeastern rim of the Šumava National Park, in the Šumava Protected Landscape Area. The highest point of Horní Planá and of the entire Český Krumlov District is a point on the top of the mountain Smrčina with an altitude of 1,333 m (4,373 ft).
Horní Planá is located on the northern shore of the Lipno Reservoir, south of the Boletice Military Training Area. Tajvan, the largest island of the reservoir, is located in the territory. Beyond the Lipno Reservoir, a densely forested area with several abandoned villages stretches up to the Vltava-Danube drainage divide (part of the main European Watershed).
During the Hussite Wars in 1420, it was incorporated into the Český Krumlov estate, then held by the Rosenberg family. The Rosenbergs insignia were adopted in the town's coat of arms. The good location on the trade route from Bohemia to Austria and later the construction of the Schwarzenberg Canal and the railway had a significant influence on the town's development.
Until 1945 the local population predominantly consisted of Sudeten Germans. In 1930, they made 98% of the population. In 1938, the town was annexed by Nazi Germany upon the 1938 Munich Agreement and incorporated into the Reichsgau Oberdonau. After World War II, it was restored to Czechoslovakia, while the remaining German population was expelled.
There is the Zadní Zvonková / Schöneben road border crossing.
The main landmark is the Church of Saint Margaret the Virgin. Its existence is first documented in 1374. It was later rebuilt in Neo-Gothic style and has preserved Renaissance murals, made between 1530 and 1580.
On the town square there is the Neo-Baroque town hall from 1896.
