Instead of taking the spiral road tunnel up to the top of Spirallen, try taking a walk up to the top along the path "Zigzaggen", which winds it's way upto the top giving fine views on the way.
An added attraction of taking this route is ?spaviljongen or "the pitstop", which is located roughly halfway up the hill.
?spaviljongen functions as both a bar to those making their way up to the top but also as a fine restaurant in it's own right.
