Chele La's ridge looks dusted with snow from a distance, but the white is cloth. Thousands of tall manidhar poles stand planted in the turf, each one raised in memory of someone who has died and left to fray away in the wind. The pass itself is the highest point any road in Bhutan reaches, a narrow strip of blacktop that climbs out of Paro's pine and rhododendron forest and tops out on a bare saddle above the treeline, with the Haa valley falling away on the far side. There is no town here and no monastery on the summit — only the flags, a few roadside stupas and the wind. On clear mornings two snow peaks stand over the tree line to the north: Jomolhari, 7,326 metres, and the narrow spire of Jichu Drake. Bhutan restricted mountaineering above 6,000 metres in 1994 and banned it outright in 2003, so this is a skyline nobody is permitted to stand on.
Most people drive up from Paro for half a day, and the pass makes them work for it: the air is thin, the wind rarely stops, and a bright ridge can be swallowed by mist within the hour and clear again just as quickly. Walk out along the crest and the poles thicken into a forest; in June and July blue poppies come up in the rocks between them. A footpath drops off the ridge through fir and juniper to Kila Goenpa, a nunnery whose retreat huts are wedged into a cliff face above Paro. Foreign visitors reach all of it the same way — with a licensed Bhutanese guide, paying the country's Sustainable Development Fee of US$100 a night. By early afternoon the cloud usually comes up out of the valleys, the parked jeeps empty out, and the ridge belongs to the flags again.
