Heading to Obergurgl in mid-March... we will miss the Easter crowds and apparently the Dutch crowds (school holidays!?). We are flying into Munich (wish we could go into Innsbruck but not an option) and then driving down to Obergurgl.
I've heard there are three primary ways... essentialy, highway down from Munich, across the border, through Innsbruch and then up the valley OR down to Garmish and either right to go over the Fern Pass or left through another area (can't remember the name). My initial thought was... well, take the highway the whole way but apparently that can get busy and the Fern Pass is usually clear and not as trafficky. I've heard German locals prefer that way.
Anyone have exprience? We land in Munich on a Saturday around 1:15 so going through Munich around 2:15ish down towards Obergurgl. We depart on a Saturday early in the morning from Obergurgl back to Munich.
I've heard about the Vignette on the highway system, as well.
