1 or 2 buses a day leave from here and can take you to the landslide at Mulling Nullah 45 min if you're headed for Lahaul and Spiti, or to Reckong Peo 4-5 hours. Times can be sporadic so enquire locally. There are also a handful of 4wd's, some working as shared taxis slightly more costly than a bus and some available for private hire.
