A friend and I are hoping to travel out to Delhi on the 24th June and gradually work our way up to Kathmandu to be there for the beginning of July. Our journey so far includes Delhi to Agra, then on to Varanasi before travelling to Kathmandu via Sunauli by bus. We've heard that the roads can get pretty treacherous around this time of year and wanted to know how feasible it would be to make Varanasi-Kathmandu journey? Is it definitley a no-no to attempt it this during the monsoon season and should we opt for plane travel between Varanasi-Kathmandu? Any advice would be greatly appreciated as we have little idea what to expect and want to plan accordingly.
Thanks very much!
