In june my wife and I will stay about 5 days each in annecy and chaminox, and we will travel by auto, any lodging recommendations. merci nicolas
I haven't been to Annecy. 5 days in Chamonix sounds like a lot to me unless you plan to hike a lot. I had a day and a half there in mid-June several years ago. It was a little early for the tourist season, so there were no long lines. I probably could have filled one more day - I missed a couple of things that weren't operating and would have liked to try paragliding - which I only found out about as I was leaving.
Just did 3 days in Chamonix and 2 in Annecy. No lodging recs, Cmx is really small, so find what you can afford.
If you want to go to the Aguille du Midi, etc., make sure they're open. Website is https://www.montblancnaturalresort.com/fr
Stayed 5 wonderful days in Annecy. We stayed at the Hotel Splendid - Handwritten Collection by Accor hotels. It had an amazing location just steps away from everything. I can't help with Chamonix, but I will say that we absolutely enjoyed Annecy and taking a few trips around the lake. The Chateau de Menthon-St-Bernard was absolutely breath-taking and worth a visit and guided tour. Talloires had some of the best views we encountered and Thônes was such a gorgeous village tucked away in the mountains.
As for restaurants in Annecy, we highly suggest Brasserie Brunet - the good was gastronomical and well-priced. Chez Ingalls' is also excellent and for fondue/raclette you cannot miss Le Freti. Reservations for each is a MUST.
Parking in Annecy can be a total nightmare. We had a car park by the hotel (Hotel-de-ville) and the hotel gave us discounted rates. But each night when we'd return from a day trip we'd have to wait for a spot to open.
