阿尔卑斯山旧地重游。我们从海拔1095米的Wildhaus (Toggenburg里的一个小村子)那边过来，一直爬到海拔2435米的“Alt Maa”（英语是old man)。我朋友攀岩上去了，我下次再挑战攀岩。沿途看到了许多野山羊！又一次在山里度过了美好的一天！

An other tour in the Alpstein. We came from the Toggenburg side (Wildhaus 1095 m.a.s.l.) all the way up to the "Alt Maa" (2435 m.a.s.l) "old man"). My Friend climbed it, I will do it next time. We seen so many Ibex! Was again a nice day in the mountains!
