I just at the bus stop. No buses - everything closed.

I think they are, maybe you can check at the turist info? But you dont need the tour agency to go on the nest, you can go by yourself. You just need the ride till the parking lots, then buy the tickets and off you go! Have a great vacation!

We drove to the Eagle's Nest as well and it was quite easy. There are tours out of Munich though - and you might try the web site getyourguide which takes tours of 4 or more to various locations (the Eagle's Nest being one of them).

As far as I know you have to buy them at the base station and get on the busses in that order. They move them along pretty fast - maybe five minute wait to get tickets, then 5-10 minutes max to catch the bus. They have rotations of busses with 3-4 going up together while another group is there blissing and another group on the way down. They also have 3-4 windows selling tickets and a store to shop at while waiting.

Weather depending...usually in May

I don't know the closing but found that going there as early as possible is better than going later. By the time we returned from the top the place was a mad house of tourists lined up. I wouldn't go late.

I guess they could be bought on line, the ticket gives the exact time slot to take the bus going up to the elevator. You can buy online if u are sure of be at the bus stop on time at the documentation centre. Usually the line doesn’t take much re then 20-30 mints but the next available time slot may be an hour or so wait as happened to us.

Buy online and deffo worth it, if it's cloudy there's always the history and you do feel top of the world

Doing all that in one day is not possible. I've visited Berchtesgaden (town under Eagles Nest) last year, I was there at 9AM, visited Eagles Nest, town Berchtesgaden where we had lunch, drove few kilometers to Königssee, went to see the St. Bartholomä by boat - A MUST SEE IF YOU ARE VISITING Eagles Nest!, and the day was over! I wanted to see the salt mines but there was no time for anything else.
