Boubín mountain is one the best known mountains of the Šumava mountains (Bohemian Forest) and of South Bohemia as well. It towers between the town Vimperk, which is situated north of Boubín, and the village Lenora, which lies at the southern foot. Boubín and the near Bobík mountain (1,264 m) form a dominant feature of the Šumava mountains.

Boubín mountain is 1,362 m high. It is a very well-known symbol of the Šumava mountains due to its height, typical outline, large forests and the nature reserve Boubínský Prales (Boubín Forest), which was already founded on its southern slopes in 1858 by the verderer of the Schwarzenbergs' domain Josef John. The nature trail Boubínský Prales (founded in 1979) leads along the most valuable core of the primeval forest.

At the beginning of 2005 the new wooden observation tower was open on the peak of Boubín mountain. It offers nice views of the Šumava mountains.
There are some stone monuments on the slopes too: the blue marked path leads from the railway station in Kubova Huť to the monument called Johnův Kámen (John's Stone) after the founder of the reserve Boubínský Prales; another hoarstone can be found on the crossing of the green, blue and red signs below the peak - it is called Křížová Smrč ("Cross Spruce") and it stands in the place, where borders of three former forest districts encountered in past; the yellow marked trail, which goes from the top to the small villages Včelná and Šumavské Hoštice, passes the other hoarstone called Monument.

Some other areas, besides Boubínský Prales, are protected here as well. One of them is the protected area Jilmová Skála (Elm Rock, 812 ha), which is situated not far from Zátoň (part of Lenora). Another area is the Milešický Prales (Milešice Forest). It lies on the eastern slope of the Boubín mountain near the monument Křížová Smrč.

The peak of Boubín mountain is accessible along the blue marked trail from the settlement Kubova Huť (about 5 km) or from the settlement Zátoň (a part of the village Lenora; about 5 km). Another way is possible along the red sign from the towns Vimperk (about 15 km) or Volary (about 20 km) or along the yellow one from the small village Včelná pod Boubínem (about 5 km). The green marked path leads from the parking-lot, which is located near the settlement Idina Pila (about 2 km north-west of Zátoň), to the reserve Boubínský Prales. The visitors then can continue along the blue marked path to the top (about 7 km).
