There are two possibilities: you can park your car at the start of the Schilthornbahn (Stechelberg) or you park at Lauterbrunnen station - from there you will have to take the gondola up to Grütschalp and take the train to Mürren. I would opt for Stechelberg, from there it's only one stop away to Mürren with the Schilthornbahn. You will have to pay for both parking lots though.
Have a nice trip,
Thank you, Olga.
