Hey there,I ain’t got all the info but if you want to travel to muktinath then make sure you get a really good sleeping bag cuz in december it will get really cold. You can rent a sleeping bag from trekking shop around Pokhara lake side street.

1.About the border i don’t know much about it and road condition cuz last time i visited only upto Janakpur via BP highway from Kathmandu. You can enter Kathmandu through Sindhuli (BP Highway) thats from janakpur.

2.For muktinath its better to take your own bike cuz renting a bike will cost around Nrs.2,500-3000 per day. Muktinath is a rain shadow area so less chance of rain.

3.Kathmandu (KTM) - Pokhara (PKR) - Muktinath and Lumbini within 9-10 days is managable but will be tiring. You can check in KTM via janakapur-sindhuli (BP Highway) then to PKR (Pirthivi Highway) then to Jomsom and muktinath and again back to PKR. From PKR you can go to lumbini via siddhartha higway via bhairhawa and check out through sunauli border which is close to Bhairahawa.

Thanks Tanzing.

Need one additional help, What are the average travel times for the sections below. I know google maps can show estimated time, but not sure if they are accurate given route conditions/hilly terrain:

1. Pokhara - Kathmandu
2. Kathmandu - Chitwan
3. Chitwan-Lumbini
4. Lumbini - Pokhara(via Tansen)
5. Kathmandu - Nagarkot
6. Kathmandu - Janakpur
