My family would very much like to take the tour to the summit of Zugspitze. We will be staying in Munich, near the main train station. I see that Gray Line tours offers a tour only on Sunday...how hard would this be to do on our own instead? It looks like we could take a train from Munich easily enough. Where do we catch the tour? Is it within easy walking distance from the train station in Garmisch? Can we be pretty certain that we will be able to join a tour if we just show up on a particular day? I have other Zugspitze questions too: is this only worth doing on a fairly clear day? Or could we get up in the mountains and see only......fog? Also, we will be there in mid June...how heavily should we dress? Would jeans and a light jacket be sufficient? Thanks for any help that you can give me.
