It can be windy and cloudy here. There are marks to find a trail in the cloud. Also on the top there is a nice area to hide from wind and rest. If not in the cloud, the view is awesome

Nice lake to have a rest in between climbs. Can be quite windy, but there are big rocks nearby to hide from wind.
