They will be starting to close down a large amount of the lifts from this weekend onwards and those that stay open will be used for downloading from higher up where there is snow. At the moment the skiing is fairly horrendous and involves walking through patches of mud and rocks. The resort should be staying open until advertised (30th April) however there will be very limited snow cover and lift access by then.
However…they are keeping the funi open until that date and are happy for bikes to go on. Last few weekends there have been up to 50 dh bikers there. The lobster pots in Peisey are also open to bikes so it is possible to ride a large proportion of the mountain, as long as you don’t mind a bit of a pedal in places. We went across the Vanoise express with our bikes the other day with no issues at all! They are encouraging VTTs in many areas around here and even doing bike rentals from the ski shops as they realise the ski season is done!
