I would think anything above 5000m requires some serious training/preparation?

Scafell Pike for a mates stag do, great trip up and down.
Does skiing count?about 3.5km is so

3,883m at the Klein Matterhorn in Switzerland. Apparently the highest cable car in Europe.
Can beat that. Gobba di Rollin ski lift in Cervinia. 3899m.

I would think anything above 5000m requires some serious training/preparation?
As far as mountains go then the top of Aiguille du Midi (3842m) with it's wonderful view of Mont Blanc and the Alps.
