Forsbanan

Forsbanan was Gröna Lund's log flume, opened in 1984 on the site of the former Jetstar II roller coaster. The 360-metre course had a drop of about fifteen metres and used six-person logs, with some 600,000 litres of water in circulation.

It was never a success: riders were soaked far more than expected, and the ride was difficult to maintain because water drawn from the Saltsjön clogged it with algae. The flume was demolished and the Jetline roller coaster later took over part of the space.
