Let's face it: Kandersteg caters to hikers, i.e. morning people. If you want nightlife, you're probably better off going to Zermatt or Interlaken (or, better yet, Amsterdam or Berlin). For those who want an after dinner drink, Restaurant Adler has a small gazebo/bar outside the main building. I've never had a drink there myself, but it seems nice.
The previous 2 tips say that there is no nightlife in Kandersteg. I've been there 6 times and I think there is.
OK, yes there is no disco/dancefloor in the village any more. There used to be one underneath one of the hotels but it got shut down for whatever reason.
These days you're left with 3 bars that will be open untill the early hours.
Ski Bar/ Hotel Victoria Ritter
High Moon Bar
The high moon bar I've only been to a couple of times. It's way out to the north of the village, but it does have a few cool features like a pool table.
I love this place. Easy to find. Right in the centre of the village on the junction.
It can get quite packed here as the locals go there too, but Cassi and Mimi are always welcoming. Live bands play here aswell as background music most nights. You can try various things here like drinking a yard of lager without sloshing it all over your face, or the snuff catapult...
The beer here costs a fraction higher than Des Alpes, but for the atmosphere and the fact that it is open til the early hours of the morning it's probably worth it.
Inbetween the village and the Scout Centre.
This one's probably my fave. Open til about half 12 in the morning and serving snacks (pizza mainly) up until about 9pm. Widescreen tv, music, outdoor seating area, smoking area, kids play area and their own car park. The majority of the people staying or working at KISC will go here at some point on their stay. Very popular. Has it's own Facebook group!
The Scout Centre runs a Disco in the summer months at the Ice Rink.
Dress Code: No dress codes anywhere.
To be honest there doesn't seem to be much nightlife in the village, so it's not the place for you if you don't come alive until 11.00 pm. However, if you prefer a good meal and a reasonably early breakfast ready for a stunning day out then it is the peace, quiet and serenity that you are looking for.
Dress Code: Generally dress in restaurants is casual. Walking sandals and shorts etc seems to be perfectly acceptable - so leave the spangly dresses and high heals at home.
Don't expect a wild club scene or posh jet-set VIP rooms in this hiking town. But there are more than a few places to get that after-dinner drink or dessert should you so desire.
