Longest mountain coaster
5,300 metre(s)
Andorra (Sant Julià de Lòria)

The longest mountain coaster (or alpine coaster) ride is Tobotronc, which has operated at the Naturlandia resort near Sant Julià de Lòria, Andorra, since 2007. The track's total length is 5,300 m (17,400 ft), with a fast-descent stage that is 3,600 m long (11,811 ft) and drops 400 m (1,312 ft) over its length.

A mountain coaster (also known as an alpine coaster) is a type of roller coaster that runs on a track that mostly follows the terrain of a hill or mountain. Typically these roller coasters use one- or two-person toboggan-like sleds, which allow the user some control over their speed, rather than the multi-person trains of a conventional roller coaster.
