Best time for My Way Alpine Tour?

We have traveled in the region in the late June-early July time frame and enjoyed it. July would probably be the better time to do it, it likely will not be as hot as August plus August seems to be the month that most of Europe goes on vacation. Actually September is great month to tour the region nice weather and smaller crowds.

I like those areas in May and June especially though July is fine too. August is hotter and most of Europe is on vacation then so it is less desirable.

We hit that area one year in July.. up on high hiking trails ( easy ones) there was still snow.. but not on paths.. locals said some paths still had snow on them even in june that year.. so I think july and august would be best.. I have been to Zermatt ( not on a tour) in August and the trails were perfect.

I did this tour in the second half of July last year. We had beautiful weather in Bolzano (Alpe di Siusi) and Chamonix. I won't soon forget those days. We had not so good weather in Salzburg, Lauterbrunnen and Fussen. Our day in Hallstatt began in driving rain and ended in bright sunshine. Based on my one data point, I would say be prepared for anything weather wise.

Due to the weather, I had the Mannlichen to Kleine Scheidegg trail outside Lauterbrunnen pretty much to myself. Unfortunately, the hike was completely in the fog the entire way and I wasn't able to see any of the spectacular views. Another reason to go back to the Lauterbrunnen Valley someday.

Crowds were huge at Neuschwanstein - make sure to get advance reservations. St. Mary's Bridge overlooking the castle was uncomfortably packed with people.

You will want to get reservations for the Aiguille du Midi in Chamonix, but I could only do so 7 days in advance last year. That meant getting reservations online while in Bolzano. I would say reserving a time on the lift earlier in the morning the better.

I don't recall having to get advance reservations for other sights along the way.

Thanks, everyone! I really appreciate your suggestions. I'm aiming for the last couple of weeks of July.
