Kongma La is a high pass at about 5,535 m in the Everest Region. It links the Chhukung and Imja side with the Lobuche valley, and it is the third crossing on the Three Passes trek. It is a demanding day, so it suits well acclimatised trekkers. Plan it with a local guide who knows the current trail.
Altitude: about 5,535 m. Heights quoted for villages and camps vary by source, so treat this as a guide.
Where Kongma La is and why trekkers cross it
Kongma La lies on the ridge between the Chhukung valley and the Lobuche side of the Khumbu. Trekkers cross it to join the Three Passes loop, which also takes in Cho La at about 5,420 m and Renjo La at about 5,360 m. It is the highest of the three, and it offers a shorter route between Chhukung and Lobuche than walking back down the valley. Many itineraries cross it after Everest Base Camp and finish toward Chhukung, though the direction can be reversed.
What the crossing is like
Expect a long day on rough ground. The trail climbs through moraine and stony slopes to the crest, where prayer flags mark the top, and then drops toward the other side. Parts can be loose and steep, and snow or ice may cover the route early or late in the season. Views from the pass take in the surrounding peaks and the glaciers below. Start before dawn, carry lunch and water, and allow plenty of daylight, since the time needed varies with pace and trail conditions.
Altitude and how you may feel
At about 5,535 m this is high enough that most people feel the lack of oxygen clearly, with slow breathing, a heavy head and tired legs. Arrive acclimatised, ideally after several nights above 4,000 m, and walk slowly. Altitude illness can strike even strong hikers. If a headache worsens, you become confused, very breathless or unsteady, turn back and descend as soon as it is safe. Do not push on to finish the crossing while symptoms are building.
Gear, food and practical tips
Pack warm layers, gloves, a hat, sun protection and sturdy boots. Microspikes or crampons are recommended on the passes, especially early or late in the season, and trekking poles help on loose ground. There are no services on the pass itself, so bring snacks and water from your lodge. Because this is a demanding high pass, go with an experienced guide, watch the weather, and allow a spare day in your plan in case conditions change.
