We bought a six days sight seeing tour of North Sikkim from Paradise Unexplored which included pickup up from NJP Rly station and drop at Bagdogra airport. The services provided by the tour operator was excellent. The vehicles provided by them were top notch and the drivers quite well behaved. Mention of Mr David Lepcha would not be out of place here because of his skillful driving in the treacherous terrains, nice behaviour and jovial nature.We had to catch our flight on the last day at Bagdogra airport at 12.15 Hrs and we needed to start early from Gangtok at 5.00 am.The vehicle arrived on time and we were able to catch our flight back home with sweet memories. Overall, a wonderful experience.
