迅速な答え
The three Khumbu high passes confuse trekkers because all sit at 5,360 to 5,535 m and all feature on the Three Passes Trek. They differ in route direction, scenery, and difficulty. Renjo La at 5,360 m connects Gokyo to the Bhote Kosi valley. Cho La at 5,420 m connects Gokyo to the EBC trail with a glaciated section. Kongma La at 5,535 m connects Chhukung to Lobuche and is the highest and least crowded.
詳細な内訳
The three passes sit within 30 km but serve different route functions. Renjo La at 5,360 m links Gokyo at 4,790 m to Marulung at 4,210 m in the Bhote Kosi valley, giving the most photogenic crossing because sunrise frames Everest, Lhotse, and Makalu above the Gokyo lakes. The ascent from Gokyo is 570 m over 4 km, the descent to Marulung is 1,150 m over 6 km, and the route is well marked in clear weather.
Cho La at 5,420 m links Gokyo at 4,790 m to Dzongla at 4,830 m on the EBC trail, with a glaciated east side that needs crampons. The ascent from Gokyo is 630 m over 5 km, the descent to Dzongla is 590 m over 4 km, and the glacier is the technical crux. Kongma La at 5,535 m links Chhukung at 4,730 m to Lobuche at 4,910 m. Kongma La is the highest, least crowded, and hardest to route find in fog.

答えに影響するもの
Pass direction is the biggest source of confusion. Trekkers often think the three passes are interchangeable, but each links a different pair of valleys. Renjo La is the westernmost crossing, Cho La the central, and Kongma La the easternmost. Choosing the wrong pass sends a trekker into the wrong valley, adding 2 to 3 days of backtracking.
Season is the second factor. In autumn, all three passes are usually clear and crossable with crampons. In spring, Renjo La and Kongma La can have fresh snow. In winter, all three close for weeks. The Three Passes Trek combines all three in one 18 to 21 day route.
予約のヒント
Book through a Khumbu based operator and ask for a route map that labels each pass with altitude and direction. Carry crampons for Cho La, because the east side glacier develops blue ice by mid October. Pack a sat messenger, because mobile signal dies above Gokyo. Reserve Gokyo and Marulung lodges 4 weeks ahead in October. Plan the Renjo La crossing as a 5 am sunrise start from Gokyo, because the morning light on Everest is the photographic high point.
代替案との比較
Compared with Cho La, Renjo La is 60 m lower, less technical with no glacier, and more photogenic. Compared with Kongma La, Renjo La is 175 m lower, better marked, and gets 600 trekkers a year versus 200. Compared with the standard EBC Trek, the Renjo La Trek adds 3 to 4 days and gives a quieter culturally Tibetan side of the Khumbu.
避けるべきよくある間違い
Trekkers often book Cho La when they want the Renjo La photo, because the names sound similar. A second is crossing Cho La without crampons in October, when the east side glacier is hard blue ice. A third is attempting Kongma La in fog. A fourth is crossing two passes on consecutive days without a rest day, which doubles AMS risk. A fifth is treating the three passes as interchangeable, when each links a different pair of valleys.
フェイク
What is the difference between Renjo La, Cho La, and Kongma La? Renjo La at 5,360 m links Gokyo to the Bhote Kosi valley and is the most photogenic. Cho La at 5,420 m links Gokyo to the EBC trail and crosses a glacier. Kongma La at 5,535 m links Chhukung to Lobuche and is the highest and least crowded.
Which of the three Khumbu passes is the easiest? Renjo La, because it has no glacier crossing and is well marked. Cho La needs crampons. Kongma La is unmarked in fog and has the most elevation gain.
Can I combine all three passes in one trek? Yes, the Three Passes Trek covers all three in 18 to 21 days, starting at Lukla and crossing Kongma La, Cho La, and Renjo La clockwise. Budget USD 2,200 to USD 3,000 per person.
Which pass has the best photo of Everest? Renjo La. The sunrise view from the pass frames Everest, Lhotse, and Makalu above the turquoise Gokyo lakes in a single composition, the strongest wide angle shot in the Khumbu.
まとめ
Renjo La, Cho La, and Kongma La confuse trekkers because all sit at 5,360 to 5,535 m and all feature on the Three Passes Trek. They differ in route, scenery, and difficulty. Renjo La is most photogenic, Cho La needs crampons, and Kongma La is highest and least crowded.
結論
For peak climbers planning a Khumbu high pass trek in 2027 to 2030, learn the difference between the three passes before booking. The Renjo La Pass Trek at 15 days and 5,360 m is the best single pass choice for photography. Budget USD 1,800 to USD 2,500 per person, carry crampons for Cho La, and book a 5 am sunrise start from Gokyo. The Three Passes Trek at 18 to 21 days is the standard way to combine all three.
