Here is the list of the challenges a trekker faces during the Everest Base Camp Trek in Nepal.

Altitude & Overnight Stay above 3000 m

Staying overnight in the places above 3000 m is very challenging if not planned properly. The cold temperature and decrease in oxygen level may be hard for you to fall asleep. Lots of trekkers complain about the loss of sleep in such altitude especially beyond 4000 m above sea level. You must make sure that you are in a warm room with adequate beddings. Sleeping in places like Lobuche and Gorakshep is comparatively difficult than sleeping in other places of the Everest Base Camp Trek route.

Availability of Tea Houses and Meals

The trail has abundant tea houses and eateries. However, the biggest challenge is to get the right tea house for you. Therefore, leave the lodging booking option to your trekking guide. Almost every tea houses has similar food menu and price structure. Food is not a problem during the Everest Base Camp Trek but the accommodation can be problem during the peak trekking season. Trekkers may have to sleep in the dining area. Interestingly, the dining area is always warm due to the indoor heating system.

Lukla Flights Vulnerability and Cancellation Chances

The headache of Lukla flight cancellation or delays looms always to the Everest trekkers. The geographical terrain and the unpredictable weather conditions can delay or cancel the flight to Lukla. This blogger thinks that the Lukla flight plays vital role in making the Everest Base Camp Trek successful or not according to schedule. Therefore, allocate at least 2 additional reserve days as the contingency plan if incase the cancellation happens.

Rugged Trail over glacier and moraine

The trail is well maintained until you reach the Thukla Village after acclimatization break in Dingboche Village. It is easy to walk on the Everest Base Camp Trek route until we reach Thukla Village. Beyond the village, the trail is full of rocky boulders and rugged path. In addition, you have to walk on glacier and moraine which can be frustrating and tiring. Therefore, prepare well physically by building up the fitness level at least one month prior to the trek.

Unstable Weather Conditions and Visibility

Sometimes, the weather changes all of sudden in the Everest region. You may not get the best scenery of mountains due to poor visibility. So, don’t get frustrated over this. Some people easily get upset if they don’t get what they wanted. It may be against your safety to ruin the mood of the trek. Expect unstable weather conditions and prepare accordingly.

Where do I do acclimatization activities in the Everest Base Camp Trek journey?

In the Everest Base Camp Trek journey, the acclimatization activities take place in Namche Bazaar and Dingboche Village.
