Everest Base Camp (EBC) Trek is considered challenging in terms of difficulty due to the high altitude, reaching a maximum of 5,364m (17,600ft), and the long trekking days, averaging 6–8 hours of walking daily.
In spite of its challenging nature, the trek is achievable with proper planning and fitness level, making it a challenging but rewarding journey. The major factors that add to the difficulty of the Everest Base Camp trek are:
High Altitude
The high altitude is the major aspect that adds to the difficulty of the Mount Everest Base Camp trek. The trek takes trekkers up to an elevation of 5,644m at Kalapatthar, where the risk of altitude-related issues is high due to the thinner air pressure. However, the problem of high altitude is not when you reach the Kalapatthar or Everest Base Camp; it is when you land at Lukla Airport, which stands at an altitude of 2,860m. Thus, trekkers should have knowledge about altitude sickness and learn about acclimatization techniques before undertaking the trip.
Longer Duration
The Mount Everest Base Camp journey is somehow longer, covering a 65km distance on a one-way and 130km round trip. The trek demands 12 to 14 days to complete, and each day involves walking a minimum of 6 hours. Walking for such a long duration while gaining elevation each day will be difficult for those who have never been part of any physical excursion. Thus, trekkers must train properly to begin the trip.
Varied Terrain
Another factor that adds to the challenges of the Mt. Everest Base Camp trek is the varied terrain that spreads across the area of Sagarmatha National Park. The terrain involves forested areas of pine, bamboo, rhododendrons, and others, which can be slippery sometimes. Likewise, it involves crossing suspension bridges multiple times. Additionally, the combination of glacial paths, stark moraines, and several uphill and downhill sections adds to the challenges of the trek, demanding good cardiovascular and leg strength.
Unpredictable Weather
The weather of mountain regions, including Everest, is notoriously unpredictable. The air thins rapidly at high altitudes, leading to colder temperatures and less oxygen, causing rapid weather changes. String winds and jet storms can occur anytime, making trekking difficult. Thus, it is recommended that you check the weather forecast before starting the trip.
