I will be travelling solo from Siliguri to make the Thangu-Chopta-Muguthang Valley trek. I don't prefer contacting tour operators. Can you please help me regarding the following, and maybe provide some contact number of drivers for these: 1) I will start from Siliguri, and reach Gangtok (via SNT bus/shared vehicle preferably) 2) As North Sikkim permit can be issued at police check post (as per the Tourism website), I want to hire a shared vehicle to Lachen : is it possible, and if yes, what will be the cost? Where can I get these? 3) Is there a police check post at Lachen, and can I get the North Sikkim permit there? (I know that I can travel up to Mangan at least without permit, because I went there in December without one and I can definitely get a permit from the DGP post at Mangan but this time I don't want to stop at Mangan [because it is far from Chopta-valley], but instead stop & arrange permit at Lachen) 4) I will stay overnight at Lachen and then make the Chopta valley trek. Will I get guides there at Lachen for this? If yes, where can I get them, and cost, etc?? 5) I want to return back to Gangtok from Lachen the next day, so, can I book shared vehicle at Lachen for this?? I start in 2 days, please advise me urgently !!
