Easy to get there from the lake. The stupas look nice, it's pleasant to walk but not much shade to hide. A few hours to see everything and do some shopping with bargaining will be enough. Very nice handicrafts!
I totally loved it. You should visit both at daytime and at night as the town seems to be like two different places. There are many food and souvenirs stalls everywhere so you can get yourself something nice and also fill your belly!
