Getting around Pahalgam is done mostly by walking, taxi and ponies. Ponies are avaialbe at officially published rates everywhere - Main market, Laripora, Aru, etc. Aru can be reached by taxi for an onward treck to Lidderwat, Kolohoi Glaciers, etc.
Aru is a great place to stay in - in the lap of nature. Options for stay here are rather limited though.
