There has been as much as two metres of snow in some parts of the Alps, although relatively few resorts are open. Upper Valais seems to have done particularly well, and Andermatt has had a good dump.
In Switzerland Corvatsch (St Moritz/Silvaplana) has a couple of lifts and one run open. In Davos there are five lifts operating and two runs open on Parsenn, with Jakobshorn due to open at the weekend. Engelberg has three runs open and five lifts. Zermatt has nine lifts operating and a handful of others set to open soon, all on the Matterhorn side of the resort. Grimentz–Zinal‘s web site seems to reckon fourteen runs are open, but the information is ambiguous – best to call the resort if you fancy checking it out.
Unfortunately the amount of piste available is clearly still quite limited as the resorts seek to build a good base ahead of the season hitting full throttle. No resorts have runs back to the resort open, so in all cases you need to take the lifts back down. Needless to say, you are generally paying a full lift price for a relatively modest amount of piste.
There hadn’t been fresh snow for a few days, but the snow looks to be coming back today to many areas over 2000m, and will continue for the next few days.
Expect a few more resorts to open this coming weekend and the first weekend in December, hopefully with plenty of fresh snow and sunny skies! Quck and dirty update of resort overview is here, with full details at resort pages at swisswintersports.co.uk.
I have Swiss insurance and am a member of Rega (the air ambulance people), but there are some gaps in terms of ski insurance cover. In many resorts there is an excellent service you can buy with your lift pass called Snowcare. It costs SFr 5 per day and covers refunds of ski pass, lessons and equipment hire if the slopes are closed, and costs of assistance and rescue, transport by ambulance and helicopter, medical expenses, sanitary repatriation and legal assistance. The amount is limited, but the ceilings seem reasonable, and the insurance is intended to supplement usual insurance and European Health Insurance Card provisions as applicable. It also does not cover off-piste activities. If you’re looking to switch health insurance, there are several options out there.
