We're arriving in Wengen om Saturday and staying for a week. It's our first time in Switzerland and we've been reading up on all the day trips we want to take. Jungfrau is the main attraction for us.
We want to go when weather is best even though we know it can be unpredictable. How far in advance so we need to buy our tickets to ensure we are able to get up there?
