The predominant attraction at Sixt is the horseshoe shape made by the mountains, which gives the place its name. It must be really spectacular in spring when the melting snow forms innumerable waterfalls crashing down the cliffs, but it was no mean sight even in August.
A river valley flows along the bottom, the point where it meets the mountains being called Bout du Monde (end of the world). Horses are a very visible presence and they left adequate evidence of their passing along the footpaths. The valley and some of the gentler passes make stables almost obligatory.
On our intended route we probably bit off more than we could chew as we had been 'over the top' the day before and traveled from Dover the day before that. Tiredness was rushing up and when we came to a point where we should have needed ropes, and we lacked the stamina to go down and make the height again. Hence we took it very easily and enjoyed the entrancing peace of the neighborhood.
However it was obvious that there are any number of walks of various levels of difficulty up into the mountains, and from what I have since heard from a friend who had the time of her life staying in a hotel in Sixt on a Ramblers (I think) holiday, there is a surprising amount of variety in the terrain.
