Everest Base Camp Trek via Cho La Pass – 18 Days

The Everest Base Camp Trek via Cho La Pass is one of the most adventurous and scenic trekking routes in the Everest region of Nepal. This 18-day high-altitude trek offers a thrilling combination of stunning landscapes, cultural encounters, and a challenging high mountain pass crossing at Cho La Pass (5,420m). This route is ideal for experienced trekkers looking for a more demanding alternative to the classic Everest Base Camp trail.

The trek connects two major valleys in the Khumbu region—Gokyo Valley and Khumbu Valley—by crossing the dramatic Cho La Pass, nestled between Cholatse and Kangchung peaks. The journey not only leads to Everest Base Camp (5,364m) and Kala Patthar (5,545m) for unparalleled views of Mt. Everest, but also includes the stunning turquoise Gokyo Lakes and the panoramic Gokyo Ri (5,357m) viewpoint, offering spectacular vistas of Everest, Lhotse, Makalu, and Cho Oyu.

The Cho La Pass section is physically demanding and should only be attempted in good weather and with proper acclimatization. While no technical climbing equipment is required under normal conditions, trekkers should be well-prepared with suitable gear due to the steep ascent and glaciated terrain. Overnight stops are typically made at Dzongla and Thangnak, with each leg of the pass crossing requiring six to seven hours of trekking.

This unique Everest circuit, curated by Alpine Club of Himalaya, combines natural beauty, cultural richness, and physical challenge. It allows trekkers to explore Sherpa villages, ancient monasteries, and high Himalayan landscapes rarely seen on the standard EBC route. For those seeking an unforgettable and less crowded route to Everest Base Camp, the Cho La Pass trek is a must-do.

Best Time to Visit

The best time to undertake the Everest Cho La Pass Trek is during the pre-monsoon (spring) months of March to May and the post-monsoon (autumn) months of September to November. These seasons offer the most stable weather, clear skies, and breathtaking mountain views. In spring, the trails come alive with blooming rhododendrons and vibrant landscapes, while autumn provides crisp air and excellent visibility after the monsoon rains have cleared the atmosphere. Both seasons are ideal for high-altitude trekking, including the Cho La Pass crossing, as snow and ice conditions are generally manageable. Winter (December to February) can bring extreme cold and heavy snowfall, making the pass more dangerous, while the summer monsoon (June to August) often results in slippery trails and poor visibility. For safety, scenic beauty, and the best overall trekking experience, spring and autumn are highly recommended.

Physical Fitness and Trekking Requirements

The Everest Cho La Pass Trek is a physically demanding adventure that requires a good level of fitness, stamina, and mental endurance. Trekkers should be comfortable walking 6 to 8 hours a day over rugged, high-altitude terrain. While previous trekking experience is highly beneficial, it’s not mandatory if you train in advance. Cardiovascular fitness, leg strength, and endurance training—such as hiking, running, cycling, and stair climbing—are recommended at least 2 to 3 months before the trek. Because the trail includes steep ascents, glacier crossings, and high-altitude passes, mental preparation and determination are also crucial. Consulting a doctor before undertaking this high-altitude trek is advisable, especially for those with pre-existing health conditions.

Altitude Sickness and Acclimatization Preparation

Altitude sickness is a serious concern during the Everest Cho La Pass Trek, with the highest point being over 5,400 meters. Symptoms may include headaches, nausea, dizziness, and fatigue. To reduce the risk, the trek includes a carefully designed itinerary with gradual altitude gain and dedicated acclimatization days in key locations like Namche Bazaar and Dingboche. Trekkers are encouraged to walk at a steady pace, stay hydrated, avoid alcohol, and consume high-carbohydrate meals. Carrying altitude sickness medication like Diamox (after consulting a physician) is also recommended. Understanding the signs of Acute Mountain Sickness (AMS) and informing your guide immediately if symptoms occur is vital for your safety.

Lukla Flight and Alternative Options

Most trekkers to the Everest region fly from Kathmandu to Lukla, a short but scenic 30-40 minute flight that lands at Tenzing-Hillary Airport, the gateway to the Khumbu region. However, weather conditions in Lukla are unpredictable, and flights may be delayed or canceled. As an alternative, helicopter services are available from Kathmandu or Manthali to Lukla, though they are more expensive. Another less common alternative is to trek from Jiri or Phaplu, which adds several days but provides a culturally rich, gradual ascent and extra time for acclimatization. Regardless of the option, planning buffer days in your itinerary is strongly recommended.

Meals During the Trek

Throughout the Everest Cho La Pass Trek, you will be served nutritious, freshly prepared meals at local teahouses. Typical meals include rice, pasta, noodles, potatoes, soups, eggs, vegetables, and the famous Dal Bhat—a staple Nepali dish of lentils, rice, and curry. Breakfast usually includes items like porridge, pancakes, toast, and eggs. While the menu is largely vegetarian, some teahouses offer meat dishes, although it's advisable to avoid meat at higher elevations due to lack of refrigeration. Snacks, energy bars, and electrolyte powders are useful to carry for added nutrition and energy between meals.

Drinking Water on the Trail

Safe drinking water is essential on the Everest Cho La Pass Trek. While bottled water is available for purchase in teahouses, it becomes increasingly expensive with altitude and contributes to plastic waste. A more sustainable and cost-effective option is to treat local tap or stream water using water purification tablets, filters, or UV sterilizers. Many trekkers bring reusable bottles and refill them along the way. Staying hydrated is also key to preventing altitude sickness, so aim to drink at least 3–4 liters of water per day.

Accommodation

Accommodation along the route is in locally-run teahouses, which offer basic but comfortable lodging. Rooms usually include twin beds with foam mattresses, blankets, and pillows. However, it’s recommended to bring a four-season sleeping bag for extra warmth, especially at higher elevations where nighttime temperatures can drop significantly. Toilets range from Western-style to squat, and some lodges offer hot showers for an additional fee. While facilities are simple, the hospitality of the local hosts makes the experience warm and welcoming.

Guide and Porter Services

Hiring a licensed trekking guide and porter through a reputable company like Alpine Club of Himalaya significantly enhances the safety and enjoyment of your trek. A professional guide not only ensures proper acclimatization and route navigation but also shares insights into the local culture, customs, and geography.

A porter carries your main luggage, allowing you to trek with just a light daypack. For comfort and ethical labor practices, one porter is assigned for every two trekkers, ensuring the workload is manageable and fair. This arrangement allows you to focus on the journey while supporting the local economy responsibly.

Travel Insurance

Comprehensive travel insurance is essential for anyone undertaking the Everest Cho La Pass Trek. Your insurance must cover high-altitude trekking up to 5,500 meters, including emergency helicopter evacuation, medical treatment, and trip cancellation or interruption. The Cho La Pass is a remote and physically challenging section of the trek, where access to medical facilities is limited. In case of injury, altitude sickness, or extreme weather, timely evacuation may be necessary. Always review the policy details and ensure it covers adventure activities specific to the Everest region.

Passport and Visa Requirements

To enter Nepal, travelers must hold a valid passport with at least six months’ validity from the date of entry. Tourist visas are required for most nationalities and can be obtained upon arrival at Tribhuvan International Airport in Kathmandu or online through the official Nepal eVisa system. It's recommended to carry multiple passport-sized photos for the visa application and trekking permits. Always verify the latest visa regulations with the nearest Nepali embassy or consulate before traveling.

Acclimatization During the Trek

Proper acclimatization is crucial for a safe and successful journey through the high-altitude terrain of the Everest Cho La Pass Trek. The itinerary includes designated acclimatization days in key locations like Namche Bazaar and Dingboche, allowing your body to adjust gradually to the altitude. Slow, steady trekking, regular hydration, and adequate rest are critical in preventing Acute Mountain Sickness (AMS). The route is carefully designed by the Alpine Club of Himalaya to maximize safety while still offering a rewarding trekking experience across varied elevations.

Entry Permits and Trekking Authorization

Several official permits are required to undertake the Everest Cho La Pass Trek, as the trail passes through national parks and restricted areas. These include region-specific trekking permits and an entry pass for the Sagarmatha National Park, a UNESCO World Heritage Site. Additionally, trekkers must register at multiple checkpoints along the trail for safety tracking and environmental conservation purposes. All necessary permits are arranged by the Alpine Club of Himalaya as part of the trekking package to ensure a hassle-free experience.

Final Notes

Before joining the Everest Chola Pass Trek, it is essential to ensure that all your gear is tested and properly fitted. Fitting boots, untested technical equipment, or unfamiliar layers can create discomfort or lead to safety risks at high altitude and test your backpack’s load-bearing comfort well before your departure.

Proper preparation, tested equipment, and open communication with your guiding company ensure a smooth and successful Himalayan adventure.
