If you are going till Kel, then do not miss Arang Kel and Taobat. At least keep one place in your plan. There is nothing to see in Kel. Arang Kel is at around 30 40 min hiking, if you want to avoid that with an infant then go to Taobat for an overnight stay. Mineral water and other things are easily available till Keran. In Kel a bit expensive but can be found.
