Cross the swaying suspension bridges high above this turquoise glacial torrent while trekking to Everest Base Camp. You will hear the roar of the 'Milk River' long before you see it. Watch for mule trains and yaks on the Hillary Bridge; it is a bottleneck, so wait your turn. Skip the low-altitude photos and save your storage for the Gokyo Lakes route where the river's source is actually visible. Bring a windbreaker.
