There are few other huts apart the one on the top.Second one is is called Slaski Dom(Silesian House)and it's located on Rownia pod Sniezka(200 meters below the summit).Other huts are: Samotnia,Strzecha Akademicka,Domek Mysliwski and Lomniczka Hut.From all these huts it's possible to reach the summit in less than 2 hours.But it's much better to spend a night in one of hotels in Karpacz and start a hike in early morning.
