The season for great trekkings is closed. Come and see you next year!
In general ways, best season for Tour du Wildhorn is from 15th of July until beginning of October.
Generally there is still snow at begining of summer, so col des Audannes is a little delicate if you are not alpinist with adequate high mountain equipment.
Some years, you have to wait until end of July. Ask to guardian des Audannes. Also after bad weather, it is better to ask.
