Is Mont Blanc ascent accessible to a beginner?

For a motivated beginner: allow 9 to 12 months of training, use a certified UIAGM guide and first climb Grand Paradis (4,061 m) or Breithorn (4,164 m).
How long does it take to climb Mont Blanc?
Two full days minimum on the Goûter route: Day 1 ascent to Goûter refuge (3,835 m), Day 2 summit and descent. Some add an extra night at Tête Rousse for acclimatization.
Do you need a guide for Mont Blanc?
No, there is no mandatory permit or guide requirement in France. But for anyone without confirmed glaciated terrain experience, using a certified UIAGM mountain guide is strongly recommended. Around 20,000 people attempt the ascent each year; 50% reach the summit.
