Cool Castles....Rule #1: Get there early to avoid the crowds!
Neuschwanstein:

Not a real castle, it's a palace, but cool anyhow! King Ludwig at his best! If this looks
like something you would see at Disneyland, that's where Walt Disney got the idea.
Ludwig loved to spend money to impress his visitors. Money was no object and it
showed.
This is what I wanted to see, yeah it's a guy thing. The little towns are nice BUT give me some armor, edged weapons and battlements ..... and I'm there!
Burg Rheinfels:

This was the biggest castle on the Rhein
before being destroyed by the French.

Bring a flash light because there are places
of interest in the castle that you can only get
to by using the flashlight. See it!!!! It's worth
the visit.
Burg Eltz:

The location alone is worth the trip, the castle just makes it better. Let's see
.... our last name is BELTZ ....do I see a connection? OK, only in my
imagination.

If you can get enough people together they will do an English speaking tour.
The tour is great because this is a "working" castle and not one of the
"fantasy" castles like Neuschwanstein.

Rheinfels overlooking the Rhein River.
Cochem Castle:

A little west of Koblenz on the Mosel River. We
happened to be here on one of the many German
holidays and the number of motorcycles, in Cochem,  
was incredible.
Linderhof:

This was King Ludwig's favorite palace, it's not as big as I had
imagined on the outside. Inside is another story. The opulence of
this place is overwhelming. Again, money was no object.

They allow you to take pictures inside, without flashes, but no video.
Our first view was through the mist right after a rainy night. To describe the
view as something out of a "fairy tale" would be a real understatement. It was
what you hope all castles would look like.
