You can book your camping gears online and collect the items from their office near Green park. Camping gears should cost around ₹700 on rent for three days.
Catch an overnight bus to Dehradun. It is recommended to book online. Buses by UP are cheaper than UK. Janrath, an AC bus run by UPSRTC would cost just ₹490
The bus journey from Delhi to Dehradun is about 7 hrs. If you catch an over night bus from Delhi, you should be at Dehradun by early morning.
Catch a shared auto rickshaw (it’s locally called Vikram) to Mussoorie Roadways bus station from ISBT. This would cost you ₹10. The shared autos ply from just outside the ISBT. At Mussoorie bus station, catch bus to nainbagh. This will cost you ₹120. There is one bus leaving at 0630.
The bus takes your though winding roads of Mussoorie and Kempty. You would cross river Yamuna on the way. This is the same road that takes you to Yamunotri (the source of Yamuna). You should reach Nainbagh in 3 hrs.
You can reach Pantwari from Nainbagh by shared jeeps. They charge you ₹50 and takes about 45 mins of travel.
This is the starting point of Nag Tibba trek. There is an ATM here. Few restaurants are here. Bhandari guest house is a recommended place for food. They allow you to use their washrooms free of cost. The wash rooms were very clean. They also serve Maggie, Parathas and bread toasts for breakfast.
Start the trek as early in the day as possible. If you are not a regular Trekker, this could feel like a bit more than an easy trek, specially if you are carrying your own camping gears. A four hour trek from Pantwari would take you to the base camp. There are two different camp sites.
The first one is right after Goat Village ( this the name of a small settlement on the trail). The views here are not great. You could stop here for lunch though. You should see tent’s set up by different travel organisations here. We stopped here for lunch at one of the camps set up by an organisation. They charged ₹100 for a plate of Rajma Chawal.
The second base camp which is almost an hour trek from the first one has better views. The second base camp is inside the forest range. You should see tent’s setup by different travel agents here too. There are no restaurants or stalls here to buy dinner. The camping organisers may provide you food on chargeable basis.
If time and fitness permits, it is recommended to skip camping at the earlier two base camps and trek till the camping area near the Nag Devta Temple. This trek is another hour from the second base camp. The views here are much better than the earlier two base camps.
Since we could not reach the temple before sun set we camped at an opening some where between the second base camp and the temple. We carried our own snacks and food for dinner and next days breakfast.
Rise early and start your trek from base camp to the summit. It’s an hours trek from the temple, two hours trek from the second base camp.
The trek back to Pantwari should take half the time you took to climb up. At Pantwari you would find shared jeeps that takes you to Nainbagh.
The last bus from Nainbagh to Dehradun is at 1545. There are also shared jeeps from Nainbagh to Dehradun and would charge you ₹200.
