Great way to see the Matterhorn. I'm not sure why there were so few people because it is really worth doing. I think it is because there is very little advertising/signage in the town about it and you have to walk about 5-10 minutes from the centre of town to the funicular.
This was our favourite excursion -fortunately most tourists go to the Matterhorn Paradise and not the Rothorn. We spent 5 hours at the top - just walking around the area - admiring the view - taking lots and lots of photos. We watched a few para-gliders take off and just admired their freedom in the air. The scenery was absolutely amazing !! Don't miss this opportunity
