A trek that takes you to the base of Annapurna 1 where you are surrounded by a circle of high mountains towering almost vertically above you. The route in is not too taxing, more a gradual push up. Starting from Birenthanti we trek up to Ghorapani for a spectacular sunrise view of both the Dhaulagiri and Annapurna Nepal.Trek along the ridge down through a river bed to reach Tadapani. The next day trek down through a wood to the kyumnu khola before a climb up to the trail that leads on to Chomrong. After leaving Chomrong we say goodbye all permanent settlements. The trek climbs through dense bamboo jungle to finally rise above the vegetation line and makes for a narrow notch between the sheer lower flanks of Machhapuchhre and Hiunchuli. Once past the sanctuary the trek ascends through glacial moraine and up to a cluster of huts ("Machhapuchhre Base Camp") where many people stay overnight. An hour or so further from here you reach Annapurna Base camp (4130m). The views within the basin are spectacular, people either spend the whole day here and lodge overnight or a couple of hours before trekking back the way they came. There is an opportunity on the return to bathe in the hot spring at Jhinu.
