Montaña Suiza ("Swiss Mountain" in English) is a steel scenic railway roller coaster located at Monte Igueldo Amusement Park, on the coast at San Sebastián, Spain.

It was designed and built by German engineer Erich Heidrich and opened at the site in 1928.

The ride was built with wooden running rails in a trough, like usual scenic railways.

Instead, the track runs in depressions set into the ground and along the top of a coastal wall at one point.

The cars are wooden in construction and ride on steel bogies, like the scenic railways at Margate, UK, Great Yarmouth Pleasure Beach, UK and Luna Park, Melbourne.
