Apparently all trains in the Chamonix Valley between Chamonix and Vallorcine are suspended all summer, until 8 December. I am unclear as to whether there is a bus replacement service (there are of course regular buses up and down the Chamonix valley but these don’t allow bikes in my experience).
When this happened while I was there last October, there was a bus replacement service but they were incredibly arsey about letting bikes on. I had to insist every time, but eventually was allowed every time. I was always the only cyclist on the bus. In July, it’s very unlikely you’ll be the only one wanting to put a bike on, so I wouldn’t count on there being effective bus replacement. I think you’ll need a car, but I’m speculating.
I can’t find any details of this closure on the CMB or Chamonix tourist websites, although amusingly the latest news story on the latter is about the Council’s commitment to climate change reduction. I heard about this merely via the Facebook newsfeed of someone who’s there who would know! Thought I better post this here on that basis, as I know there have been threads discussing trips there. Something to look into.
There is still plenty of good riding between St Gervais and Chamonix, but still, this is very disappointing. It should never have been allowed – appalling really, not least because the trains were also shut more or less ALL October and November last year, I recall. Just what are they DOING? I wonder if this has something to do with the big storms there have been this spring.
I still think Chamonix probably has the world’s best backcountry-style singletrack riding, with only Verbier as a competitor, but the infrastructure just gets worse and worse each time I go there. Lift closures are irritating but I don’t mind cycling up and the best stuff is not covered by lifts in any event. But you do need that train!
