Eagles Nest

Hi Cathy - You probably want to post your question in the Austria Destination Q and A forum. This one is for reviews of everything from museums to Accommodations and restaurants by people who've already been to them. This is the forum you want:

https://community.ricksteves.com/travel-forum/austria

And be specific about where "there" is ("We're traveling there in June.") Salzburg? :O)

Eagle’s Nest is in Germany, not Austria, near Berchtesgaden. Do not move it to Austria!
It was Hitler’s mountain top retreat. We drove there, parked, took a required bus to the site. You take a huge elevator up through the middle of the mountain. Gorgeous views at the top, but you can feel Hitler’s paranoia at retreating to such a remote place.
Ask the RS staff to change your country tag to Germany.

The OP may know it's in Germany. It appears to be a popular day trip from Salzburg, and one of the OP's other posts indicate that they'll be visiting that city.

There is only one way up to Eagles Nest. You take a special bus up the mountain. You can’t drive up on your own. This site might help:

We spent about 3 hours there, including lunch. Busses leave frequently. The views are spectacular on a clear day. Not sure I’d go on a cloudy day.

If you are considering this as a day trip from elsewhere, you need to factor in travel time from wherever you are staying. You easily can spend a full day in Berchtesgaden between Eagles Nest, Konigsee, the salt mine and the town itself.

Busses leave frequently.

I've been there three times in the last 25 years, but not for 10 years. I doubt that they have changed this.

When we've arrived at the bus parking lot, we've always been told to book our time for the return bus trip. That will determine how long you will stay there. I think I've always booked a bus for 2½ or 3 hours later. I think I've always had lunch at the test. One time we hiked up the hill to the cross above the nest.

Here is a link that will tell you the information regarding how to get there. If you take your time seeing the site and walking around the outside area and get a bite to eat, I think 2 hours is plenty. There are guided tours that are available that will add context. I spent 2 nights in Berchtesgaden. It is a beautiful area.

There have been quite a few "corrections" on this thread and I will add another one. Hitler did not like Kehlsteinhaus and only rarely went there. It was a birthday gift to him that he didn't really appreciate. Plus, is it paranoia if they really are out to get you?

I appreciate all of the information shared. As we will only be in Salzburg for a full day, the RS info. suggested a day trip to Eagles Nest, which is on our to do list. All of your input will be taken into consideration. "Keep on Traveling!"
