My wife and I have only been to Disneyland once, but it was certainly a memorable trip! From our hotel room (the Howard Johnson across the street) we could see the Matterhorn mountain.
We loved watching the monorail glide past it as we stood on our balcony. It was also visible from the Casey Jr. train and the Storybook Canal boats:
No matter where you are in Disneyland, you can see this iconic mountain!
