The mountains around Chamonix are majestic. If you choose to venture into these mountains, chances are you'll return a bit more humble. I went to Chamonix as a 19-year-old kid looking to spread my wings and experience a mountain culture different from that which I grew up around. My eyes were opened as I threw myself into some of the most immense terrain in the world. The second day, I skied Cham, and I decided to hike up to a nice fresh patch of powder that only had two other tracks on it. I realized that there was a reason no one else skied there, as I straddled a knife ridge and eased my way across an unnerving 200-foot section of mixed rock and ice that dropped off 500 feet on each side. If you aren't into the adventure aspect, you will still enjoy a visit to this amazing town due to the breathtaking vistas, small-town ambience, and lively nightlife.
Quick Tips:
Hire a guide if you plan on skiing Mer de Glace, as it is easy to become disoriented on the glaciers. I didn't feel comfortable in the area until I had been skiing there for 2 or 3 months.
Any of the equipment rental shops on Rue du Paccard can outfit you with whatever gear you will need (skis, harnesses, transceivers, etc.), although this equipment is useless unless you know how to use it and are with a guide/other experienced people.
The ski areas are the busiest during British holidays (mid- to late February). The tram lines can get brutal during these times. I've waited for 2 to 3 hours just to get up the hill, so try to plan accordingly.
If you plan on partaking in the nighttime activities, bring your liver and some extra pain relievers.
Best Way To Get Around:
You can walk anywhere in town. The public transport system is great for taking you from one ski area to the next. Fares are cheap, and many of the hotels in town offer free bus passes. Early and late buses are less busy than the peak buses, but the longest you will have to stand is 20 to 30 minutes. For travels in and out of Chamonix, trains are very efficient and run frequently.
