As the whole crag lies on 2000 meters, the season starts around late May / June. The hillside points towards south, so despite the high altitude the sunny summer days can be warm. Thanks to the many sunshine hours in this area, the season lasts until late autumn. The most ascents are usually in July and August (probably connected to summer holidays), but if you need really good friction, climbing is possible here even late September / October, if the weather is fine.
