"Treetop Adventures For a different view of Saas-Fee, tackle the ropes course in the town's Adventure Forest. Four courses increase in their degree of difficulty with obstacles ranging from monkey bars to tight rope walks. The last two sections are a true test of balance and agility. Try to keep calm and enjoy the spectacular views of the distant mountains as you walk across wobbly planks and swinging ropes high up in the trees. The course ends with a ride down the longest zip lines in Europe that cross over the gaping Fee Gorge. Hold on tight and try not to scream too loudly."
