Thunderbird is the first GCII-built rollercoaster outside USA and also the most northerly wooden coaster in the world. The design contains a variety of smaller hills giving a lot of lateral G-force and airtime - there's absolutely no breaks to cool down and have a look at the view. The most unique feature is probably the curving double-down hill soon after the first drop, which was named Lillbacka Cutback by the owner/family behind the park.
