Hi Swift2008
The problem you're going to have is what not to see. Your best bet is to make sure when you travel use the trains, we did and they are fantastic. The best trips I would reckon are either up the Grindelwald valley or the Lauterbrunnen valley.
Must sees are as follows: The Trummellbach falls, not to be mixed up with the Reichenbach falls. Jungfraujoch, is the highest railway station in Europe and is just below the summit of the Jungfrau, the train wends its way up for two hours with a change in Kleine Scheideg and then the track goes up steeply and actually through the Eiger emerging at 11333feet at the Jungfraujoch where you can shop, eat, go sledging or skiing or dog sledding.Tip: plug your telly into the bollard at the camp site and go to channel 14, they have live cameras of the weather conditions at the top of all the high attractions, the trip is expensive unless you have a swisscard which will bring the price down or even make it free I don't know. We bought a pass which gave us everything half price and those were roughly 100 francs each (
