The Everest Base Camp Cho La Pass trek is a strenuous and challenging trek. It combines high-altitude trekking with the technical challenge. Here are some factors that contribute to the difficulty of the trek:
Altitude
The trek reaches altitudes over 5,000 meters (16,404 feet), with the highest point being the Cho La Pass at approximately 5,420 meters (17,782 feet). This leads to thinning of oxygen levels at higher altitudes. Thus, it makes the trek more challenging.
Terrain
The trail over the Cho La Pass is rocky and can be icy, especially in the early morning or late afternoon. You can encounter slippery paths, which need a careful footing. The route further includes steep climbs and descends, making it physically demanding.
Weather
Weather in the high Himalayas can change rapidly, bringing snow, strong winds, and low temperatures, particularly at the pass. Even during the best trekking seasons, temperatures at night can drop significantly, and it can be very cold on the past.
Physical Fitness
The trek requires a high level of physical fitness and endurance. Daily trekking can range from 5 to 8 hours, with longer days when crossing the pass. Physical preparation and training before the trek are essential to handle the physical demands.
Technical Difficulty
The Cho La Pass involves crossing a glacier covered with snow and ice. Some sections may require basic mountaineering skills, such as using crampons and an ice axe. There may be crevasses on the glacier, which require careful navigation.
