Ski areas near Thun and Bern, Switzerland

I wasn't really sure where else to post this but thought there might be some TTers who live in Switzerland or know the area well.

We are heading down to Nendaz, 4 Valleys from Frankfurt for a weeks snowfun in Nendaz starting from Saturday. Now to break our journey down we thought about travelling down on Friday night and stopping possibly in Thun and then skiing somewhere locally on the Saturday before heading off down to Nendaz.

Can anybody recommend somewhere nice for the day for us? We can probably be described as advanced snowboarders and would love some off piste if there is anything available (I know weather is not great at the moment though)

The only reason I have chosen Thun is because of a work trip in Milan I will be getting the train from there and my boyfriend will be driving down from Frankfurt. So it looked like somewhere easy for us to stop - we could also go for Bern or anywhere on that main train route.

Does anybody have an insider tip for us? Thanks in advance.

Have a look at these places:

PS: Just saw you posted to the last link, where even they say head south...

Not local knowledge, but I've found the best site for locating Swiss (and Austrian) ski areas to be www.bergfex.com . It shows all the ski areas on a map, and you can click on to find a brief description and link to the resort website. I've found it to be pretty accurate.
