Les 3 Vallées edges ahead in more categories, though the gap is close. Both are excellent resorts.
Chamonix-Mont-Blanc has significantly more vertical: a full run takes noticeably longer and the mountain feels much bigger.
Both resorts receive similar annual snowfall, so you can expect comparable snow conditions at either.
Les 3 Vallées has a slight edge in beginner-friendly terrain, with a bit more dedicated green-run acreage.
Les 3 Vallées is much larger: significantly more trails means more variety and far less chance of skiing the same run twice in a week.
Les 3 Vallées's higher base elevation helps snow stay cold and dry longer, giving better conditions through the day and into spring.
Chamonix-Mont-Blanc is easier to reach: one flight to Geneva (GVA), then about 1h 21m to the base. Les 3 Vallées means one flight to Chambéry (CMF), then about 1h 49m to the base.
Les 3 Vallées has more beginner-friendly terrain and is a lower-pressure environment for new skiers.
Les 3 Vallées wins on the stats that matter most for experienced skiers: more mountain to explore over a full week.
Les 3 Vallées is the better pick for beginners. It dedicates more of its mountain to green runs and easy terrain, which means less time hunting for appropriate slopes and more time building confidence.
Les 3 Vallées (700 cm/year) and Chamonix-Mont-Blanc (762 cm/year) receive similar annual snowfall. Neither has a meaningful snow advantage; other factors like aspect, elevation, and grooming matter more day-to-day.
Les 3 Vallées is the larger mountain by trail count (Les 3 Vallées: 327 trails, Chamonix-Mont-Blanc: 121 trails). On a week-long trip, a bigger mountain means more variety and a lower chance of feeling like you've exhausted the terrain.
Chamonix-Mont-Blanc has a higher percentage of expert terrain. If you're an advanced skier who will spend most of your day on black and double-black runs, that extra challenge is worth considering when choosing between these two.
Les 3 Vallées is generally the better family resort based on its terrain mix. More beginner-friendly slopes means children and less experienced parents have plenty of room to ski without feeling pushed beyond their comfort zone. That said, both resorts have established ski schools, so check current program reviews before booking.
