The route into Makalu Base Camp is frequently used by expeditions and a busy year sees up to five mountaineering groups attempting to climb the world's fifth highest peak. Now that the Barun-Makalu National Park has been set up trekking traffic is increasing. Lodges are developing to cater for individual trekkers but with large gaps in the facilities it's a long way off being a teahouse trek. Also, in contrast with many of the longer popular treks in Nepal visiting Makalu usually means retracing your steps - apart from a serious mountaineering alternative. This is not an easy or safe trek to do alone. Go with a few friends, experienced porters and, if there are more than a few members in your group, a sirdar or guide.
