And if you have been travelling in Asia for a while and miss something, try the Hsipaw pizza (or family burmese food) at Ma Ma Gyi noodle shop (proudly made by my sister and my mum. Well this is my website after all, fair enough to promote some family business :) ). You can find them at 22°36'50.7"N 97°17'59.7"E , in the center of Hsipaw downtown.
note that there is no signal for most of the tour. There is the possibility to charge phone/camera in the villages, but note that they rely on solar panels mainly.
