You do not have to be a serious climber. From the station of the cablecar, it takes only two hours to the summit. You should go there between June and September, as it would be too cold or the cable cars are not running. Try to go there when the weaher is good. When it is fine the view is splendid. When it is fine, it is fairly easy to get to the summit, but I would recomend you to wear shoes suitable for trekking.
