The Makalu region is an absolutly amazing still very untouched area in the northwestern corner of the Sankhuwasabha district. To the west, it is bordered by the Everest region, to the north by Tibet, to the east by the Arun river and to the south by the Sabha river. It just so happens that this very pristine area was dedicated into a national park and conservation area in the early 1990's. The park is still at its beginning stages. Though struggling to make its mark, it has done fairly well. Unlike the Annapurna Conservation Area Project (ACAP), the Makalu Barun Conservation Project (MBCP) is set up a little differently. It is definitely heading down its own unique path. MBCP is trying, I feel, to develop the area at a rate which is not degrading to any of the systems going on within the park. Tourism seems to be very low on its agenda. The Park hopes to put off that burden as long as possible knowing that it will affect the area drastically if promoted without mediation and direction. But the district of Sankhuwasabha is huge and the park makes up about only one-third of the total area. The region is very close to the Everest region, but drastically different in many ways. Most of the people in this district live in the lower hills with the highest concentrations in the most southern third of the district. A blanket statement could be made that most people live fairly close to the Arun river. The major castes in this area include Gurung, Rai, Tamang, Chetri, Brahmin, Limbu, and Sherpa (Bota), almost numerically in that order.There are many ways into the Makalu region but the primary route is to fly into Tumlingtar (the only airport in Sankhuwasabha) and hike the trail from Khandbari to Num, then cross over the Arun River into the conservation area. The traditional way is to hike in from the roadhead (Hile), but the bus from Kathmandu takes close to 18 hours and the walk to Tumlingtar takes at least two full days. There is also the Salpa Pass route between Tumlingtar and the Everest region hitting the trail there about a day from Lukla. This "backdoor" to Everest from Tumlingtar to Lukla takes at least seven days.
The Arun Valley is an incredible area, but one drawback is the heat. Since the average elevation between Hile and Tumlingtar is around 1000 ft, it is hot all year around. The Hile roadhead is about 6000 ft but quickly drops down to about 1000 ft in a 4-6 hour downhill jaunt. Once one reaches the Arun's level, the trail follows the river all the way to Tumlingtar. A remarkable area for those who have the time and don't mind the heat. From Tumlingtar, the trail mounts another ridge and continues on to Khandbari (3600), Chichila (6500), and Num (6000). The trail then takes a steep two-hour decent to the Arun River before again starting up a very steep trail to Sedua and Tashigaon and on to Makalu base camp (15,800).
