A trek was on the cards when we rolled into Lige, the ugly tourist hub of Lugu Lake, but we didn't really know where to go, or how far it was. Some locals said 8 days. Neither did we have any food, pepper spray (those Tibetan Mastiffs aren't encouraging, or really the mojo. On our way out of the area, at the much nicer main town beside the lake we found this in an informative guesthouse. Hope it might help someone in their plans!
