We were intending flying out to Kathmandu, but the 50 minute flight was $335 each, so we rented a Land Cruiser and driver from the Yak Hotel, for $300, and drove down to the border. It takes two days and one night if you drive directly, stopping in Lhatse for the night. You could also take a few more days and stop at Gyantse and Shigatze which are right on the way -- or at Nam Tso and camp out with Nomads. There is a massive amount of building on the road and the Chinese say that by 2007 it will be mostly asphalt, but now the 17 hour journey is about 5 hours asphalt the rest dirt. Great trip though, you go past Mt. Everest, and the scenery is spectacular, especially the journey downwards after you have crossed the last pass at 17,800 ft. Within three hours you are at 6,500 ft, driving down this amazing road, with a shear drop on the gorge side of 3,000 feet, through a huge ice avalanche. We just sat there chanting "Om ah hum, badzaar Guru Padma siddhi hum" with our fingers crossed. We made it and spent the night at the border town of Zangmo, which is a town that shouldn't really be there; the buildings cling to the sides of the gorge, and thousands of Nepalese trucks line the road, there to pick up the cheap Chinese electronics, running shoes etc, to take to Kathmandu. After crossing the border, you take a taxi for 10 yuan to the Nepalese side where you get your visa,($30), and from there you can hire a taxi for around 3000rps, about $40, for the four hour ride to Kathmandu. You can also get a bus from there but it takes around six or seven hours. We always stay at the Mustang Holiday Inn in Thamel (firstname.lastname@example.org), for around $15-$20 per night but at the weekend there is a lot of noise from a Disco nearby. Other nights it is quiet.
