I feel that the scenery in Switzerland is very weather-dependent. When the weather is good, it is absolutely beautiful! When the weather is bad and the fog is heavy, you can't see anything clearly.
We went there on a rainy day. When we first arrived at the mountain, we could still see some scenery, but after a while, the fog came and we couldn't see anything.
There are many ways to go to Mount Rigi. You can take the volcano to the mountain train, or the boat to the mountain train. When going down the mountain, you can change the train to the cable car and then take the boat. If you come out from Lucerne, the transportation connection is good, and it takes two hours one way.
With a Swiss pass, you don't have to spend money on transportation throughout the whole journey.
By the way, there are stones transported from Mount Emei on Mount Rigi, you can check it out.
