Perhaps not as prominent of a mountain as the other ones you could climb in the alps but a good training ground. Funny enough quite comparable to the Snowdon hike. Krim is 1,107 metres tall and you start the hike from Iški Vintgar at 420m so a height climb of about 750m. The climb from Pen-y-pass (559 m) to Snowdon (1,085 m) is about 526 metres or 817 metres if you start from Llyn Gwynant.
