We did this cable car trip in July but there was still lots of snow up in these majestic mountains. We loved the ride and the magnificent views. We really enjoyed the Ice Palace which has been carved into the glacier. It was fascinating to see the crystals from which the ice is formed. The carvings are really lovely and quite something to see. We went as a couple but were both sliding down the ice slide and taking pictures of each other coming out the other end - it had to be done and was great fun!! Although we were amongst snow and ice the weather was warm and we only needed summer clothing. It was beautifully sunny and bright and outside we needed our sunglasses with the brightness of the sun off the snow. We did not experience any negative feelings due to the altitude whatsoever. We would certainly recommend this trip - it is something quite wonderful.
