It's easy to get to the top of the Aiguille Rouge, whether you're on foot using the Pass Piéton+ or your Pass Classique/Essentiel/Premium.
If you're in Arc 1800, take the Transarc gondola, then ski or snowshoe down to the Varet gondola or the Arcabulle chairlift. Then take the Aiguille Rouge cable car. It's quite fast, so make the most of the view on the way up.
If you're in Arc 1950, take the Cabriolet cable car to Arc 2000, then the Varet gondola and the Aiguille Rouge cable car.
If you're in Arc 2000, this is the quickest way, just take the Varet cable car and the Aiguille Rouge cable car to the summit.
If you're in Bourg-Saint-Maurice, it takes a lot longer but it's also a great way to go. You can take the Les Arcs Express funicular up to Arc 1600 in 7 minutes and then take a shuttle to Arc 2000. You know the rest.
If you're a pedestrian, there are two passes:
The Pedestrian Pass
1 day 21€ or 17€ reduced rate (for 5-12 year olds and 65-74 year olds)
6 days 81€ or 65€ concessions
In addition to the Varet, Aiguille Rouge and Arcabulle lifts, you'll also have access to the Funiculaire, Transarc 1&2, Villards Vallandry and Peisey.
Piéton+ Pass
1 day 23€ or 19€ concessions
6 days 93€ or 75€ reduced rate
You'll have the same access as the Pass Piéton with the addition of the Vanoise Express and above all access to the fast lanes, which can save you a lot of time.
What's more, you'll get discounts on the Tyrolean traverse, the 1800 toboggan, the 2000 toboggan and the Fresques Lumineuses de l'Aiguille Rouge.

If you can see a lot of clouds from Arcs 1800 or 2000, now is not the time to climb to the summit. It would be a shame not to see anything.
