Lawudo (altitude circa 4,000 meters/13,000 feet) is situated in the highest area of Solukhumbu, the northeastern region of Nepal bordering Upper Tsang in Southern Tibet.
There are two ways of getting to Lawudo.
Fly and Walk
The quickest and relatively easier way is to fly from Kathmandu to Lukla and then walk for 2-3 days from Lukla (2,800 m.-9,100 ft.) to Namche Bazaar (3,440 meters/11,180 feet). It is strongly recommended to have a rest day in Namche Bazaar for high-altitude acclimatization, especially for those living at sea level. During the rest day you can visit various interesting places like Hotel Mt. Everest View, Khumjung, etc. It is recommended for the acclimatization process to walk higher up and sleep lower.
Lawudo is a further 3-5 hours walk up a very steep path from Namche Bazaar.
Drive and Walk
An alternative is to use vehicle transportation from Kathmandu to near Lukla, and then walk to Namche Bazaar.
If you have time and like to walk: first travel by bus from Kathmandu to Jiri, which takes around 10 hours. Jiri has long been the traditional starting point for the approach trek to the Solukhumbu region. The trek from Jiri to Namche Bazaar takes 9 days and is a great way to see some of Nepal’s spectacular countryside.
Visiting Solukhumbu
Whether you decide to start your walk from Jiri or from Lukla, you will find plenty of teahouses and lodges offering overnight accommodation on the trail. As Lawudo is situated in the Sagarmatha (Everest) National Park area, visitors will have to pay entrance fees in Lukla. Current pricing can be found on this Nepal Tourism Board Park entry fee page. The Khumbu Pasang Lahmu Rural Municipality trekking permit is also required. Fees are detailed on this Nepal Tourism Board Trekking Permit page.
Namche Bazaar is the main administrative center in the Solukhumbu region and has shops, restaurants, bakeries and hotels with hot showers and ATMs. All the treks to Everest base camp from the Nepali side leave from Namche Bazaar. However, prices are much higher than in Kathmandu!
It is strongly recommended that you use a porter to carry your backpack unless you are very fit and used to walking in high altitude terrain. In any case you will need to hire a porter/guide in Namche Bazaar to show you the way to Lawudo.
