There are lots of pokestops at Chabel, Kathmandu. I have been playing this game since last week. Already entered the gym of Jay Bageshwori. I guess there is gym at Pashupati Nath temple area too. Getting pokemons is easy at Chabahil area than other areas. I have friends from New Baneswor, Bhaktapur, Koteswor and Lalitpur areas who play pokemon go but get to find that my area has more pokestops (or may be I roam much more than they do). I have been to katunje sallaghari, Bhaktapur too and there were few pokestops but no any gym.
