I am going to be in Interlaken in mid-April and am looking for a half-day trip to make from Interlaken. I have heard Grindelwald has great scenery, but is it worth a quick trip that time of year (seems many things are closed for winter and not yet open for summer)? Just looking for something a bit more scenic than Interlaken to walk around and enjoy nice mountain views, perhaps a pub or two. Also, is the train ride from Interlaken-Grindelwald scenic? Thank you for your help!
