Annapurna is a ring of snow peaks closed around a single hidden basin, and the way into the middle of it is a footpath rather than a climb. The Annapurna Sanctuary is a glacial amphitheatre with one way in: a narrow gorge cut by the Modi Khola river, which opens without warning into a bowl walled by summits on every side. Guarding the gate is Machapuchare, the sharp "Fishtail" peak that has never been climbed and stays closed to mountaineers because it is held sacred to Shiva. Above the far rim stands Annapurna I at 8,091 metres — the first mountain over 8,000 metres that anyone ever climbed, reached by a French team in 1950, and still the deadliest of the giant peaks.
The way in is a walk. From the lakeside town of Pokhara the trail rises slowly through terraced rice fields, moss-hung rhododendron forest, and the stone villages of the Gurung and Magar. Most trekkers take about a week to reach Annapurna Base Camp at 4,130 metres. Inside the basin you are hemmed in on all sides by ice. At first light the summit of Annapurna I glows red, the air smells of cold stone, and the only sounds are prayer flags snapping and the distant crack of the glacier shifting. After dark, far from any town, the Milky Way arches over the peaks. The whole Sanctuary now lies within the Annapurna Conservation Area, Nepal's largest protected region, and every trekker carries an ACAP permit and a TIMS card. No rope and no ice axe are needed to stand at the very heart of the high Himalaya — only the week of walking that gets you in.
