The fantastic Jungfrau Region in and around Interlaken area is perfect 4 star hotel prague for a 4-day sojourn - the essence of glacier-girdled Switzerland etched perhaps in your mind's eyes - toylike trains and thrilling aerial gondolas - cute Alpine 4 star hotel prague villages with cozy guest houses and views from Balconies to kill for - an Alpine Wonderland and not far from Zurich by train - and trains are the best way to explore this area as cars are simply not allowed in many Alpine areas.
If going by train consider the 4-consecutive-day Swiss Pass which would cover all your transportation in Switzerland practically from get there to get go - trains, lake boats, city trams, 4 star hotel prague buses and also free entry to 400+ Swiss museums - and there is a 2 for the price of 1 sale on 4-day Swiss Passes 4 star hotel prague now if traveling before the end of November - making this, if traveling with someone else a great deal.
Swiss Pass lets you take any train anytime - just hop on with a very few exceptions - like the Glacier Express official tourist train - you can hop on local trains on the same tracks but must pay a supplement to use a pass on the Glacier Express and a handful of similar trains you never have to take - in the Jungfrau Region it covers trains in full up to Grindelwald, Wengen and Lauterbrunnen and Murren - but to the Jungfraujoch summit from Grindelwald or Wengen it gives just 25% off - very few exceptions.
I should have added that yes you just hop on any train anytime and then I should have said the conductor will come along and glance at your pass to see if it is valid - and IME it is just a quick glance - so so easy.
