Tubes, Mountain summit in Baranya County, Hungary

Tubes is the second-highest peak of the Mecsek range in Hungary, rising to 611 metres. A ridge connects it southeast to the 577-metre Kis-Tubes and on to the 535-metre Misina. Its bedrock is grey Anisian Triassic limestone, often exposed as rock ledges, and its southern slopes are steep with little soil. The 22-metre János lookout tower, with its upper viewing level at 16 metres, was completed in 2001.

The name comes from the Hungarian word 'tuba' referring to wild doves that once lived on the slopes in past times. This connection to local wildlife became part of the mountain's identity and naming tradition.

The name Tubes is of uncertain origin: one theory links it to "Tubica", a word for wild dove, giving the sense of "dove forest"; another traces it to a Türbös form from the Turkish "tür" (to fold), referring to the shape of the ridge. On the Second Military Survey map it appears as Türbös hegy. The Rotary study trail, a 4 km loop around the Nagy-Tubes and Kis-Tubes with 24 stations, was built in the early 1930s from a private donation by Ereth Ede and is marked with a yellow circular trail sign.

The János lookout is reached on foot: the 4 km Rotary study trail, marked with a yellow circle, loops around the Nagy-Tubes and Kis-Tubes. The tower's upper viewing level stands 16 m up, and the Lapis junction at 530 m on the northeast side links the trails.

The 22-metre János lookout tower opened on 15 September 2001, funded by public donations through the Tubes Lookout Foundation. It replaced a 1910 stone tower of 32 steps, named after its designer Rauch János in 1918 and demolished in 1981 when the military tower was built.
