I have a 30+ page document of hikes, things to do, transport and lodging tips, etc. in the region. Happy to send it to you. If you want a copy send me a private message with your email address and I can send it to you that way. The document is written from a Wengen base (my favorite village in the Bernese Oberland) but easily translatable to a Mürren base.
Mürren and Wengen are very different than Grindlewald. The former are small, car-free villages up in the mountains. Grindlewald sits at the base of a mountain, is full of traffic, tourists, and shops.
Yes, you can walk from Mürren to Grindelwald. Unless you are a very experienced mountain hiker or use public transportation for part of the trip it will take you two days to get there. There are more interesting hikes in the area.
