Cycling in the high mountains. Alps, Dolomites, Pyrenees etc

Ooh, ooh I can answer some of this.

Firstly, a great choice of climbs those are all crackers.

Secondly most of these can be knocked off from one location which is Saint Michel de Maurienne, in fact the Telegraphe actually starts from a right turn on the main street (assuming you are heading south arriving in the town). :

• Lacets de Montvernier, rideable from the town
  
• Col du Télégraphe, starts in Saint Michel
  
• Col du Galibier, follows on from Telegraphe
  
• Alpe d'Huez is a long ride or a short drive away
  
• Croix de Fer/Glandon both rideable
  
• it's not on your list but Col de la Madeleine is easily accessible from here too
  
  

Best place to stay with a camper is Le Marintan which has chalets, a hotel, parking spaces with power and water hook-ups and spaces for tents. Prices are very reasonable too. I've stayed in one of the chalets there and the showers/toilet block is good too.

Saint Michel de Maurienne is not a particularly pretty town but the above means it is a great place to start riding from.

If you want a slightly nicer town then Saint Jean de Maurienne is 15km north although this adds a few more klicks onto any ride you have planned and not having stayed there I don't have any recommendations.

Alp d'Huez. - 100% skip, its awful, like riding up Layhams but with lorry traffic, roadies wank on about it which makes it even less attractive, do Sarenne instead
Lacets de Montvernier. - Thats like a 15 min ride/climb, go up Grand Cucheron in spare time. Lunch here: https://goo.gl/maps/xhSHG6im26AD1zfM8 Just in the 'lacets' category the bit on grand colombier from culoz bangs
Col de l'Iseran - Not done this but everyone says start at val d'isere, there is a BANGING bike path next to isere river, see how far it goes from Tignes/Bourg St Maurice
Col du Télégraphe. - Just a little lump on the way to Galibier, hot chocolate/ice cream in Valloire, @pastry_bot rode this, he rates it: https://www.cycling-challenge.com/col-du-galbier-via-col-dalbanne/
Col du Galibier. - Love this, decent climb, cars can be cunty, try not to ride on a weekend.
Col de la Croix de Fer. - Got to be done from Saint-Jean-de-Maurienne, we made a mistake and rode from Bourg-d'Oisans, long and a little boring from that side
Cormet de Roselend - BANGS, take gravel bike and do the lap of the lake from the top of col du pre

To be very honest, the unknown/alternative climbs in the alps bang much more so than the popular ones but if its your first trip, get it out of your system. I'd even go as far as and say that ride half of those but ride the main road one day and a 4x4 track next. @platypus and @fussballclub said this before my last roadie trips. This year it was my 5th or 6th trip and I finally embraced gravel, never riding road again.

@fussballclub @andyp @pastry_bot might add more to this, much more experience than me

This is the place to get a case of wine on the way home/there btw: https://goo.gl/maps/W3VRgxLtkpfoALo39

Repeating other tips here but some thoughts and photos to get you in the mood. V jealous. Riding in the mountains is just the best.

Do Col de l'Iseran. It's my favourite climb ever, so wild and beautiful. Do it from the Bonneval side as it's a big road up to Val d'Isère otherwise, and ridiculously long.

+1 for doing the Cormet de Roselend via col du Pré. That way you go over the dam and join the main road for the last few k. It's a tough climb, and I'd had a big Beaufort cheese pie at the bottom so was feeling heavy. This is the view from the top of col du Pré.

The Madeleine is lovely and surprisingly quiet. Good burger at the top too.

Also agree that smaller lesser known climbs can be great. Look out for balcony roads that link up the villages on the mountainside. Did a great one up from Aime in the Isère valley, which links back up to Bourg st Maurice. V rough road though so wouldn't descend to Aime.
