Yes, the trial is slightly difficult but the happenings are truly worth every hurdle. You’ll have to move towards the eastern bordered hills of Nepal to experience this beauty.

The eastern part, the Kanchenjunga area, is as beautiful as the rest of Nepal. But, the broad and vigilant scenarios, taller snow-clad mountains, diverse vegetation, and attractive lifestyle and culture of locals make it rawer and sought after. Hence, don’t just have Kanchenjunga mountain in mind when there is a full package of adventure.

It is a high altitude trek that makes you reach Pangpema(Kanchenjunga’s North Base Camp, 5065m) and Ghunsa(5,140m). The trek to ascend those high areas is awesomely scenic and adventurous.

As Kanchenjunga is getting more focus nowadays, the trekking is changing its face from the former. It’s like the most rural trek of Nepal that means Kanchenjunga trekking is not as evolved as the Everest Base Camp Trek. There will be times when you have to spend overnights in concisely installed campsites. But, that experience will be a newer and exciting one. Do it in the upcoming September or any other months to relate what we are talking about.

On the way from one to another pass, you’ll reach the famous Everest Base Camp and Kala Patthar too. For this reason, the Three High Passes Trek is the best deal to do if you want to experience all the Everest region in one outing.

You’ve surely heard about the unconditional beauty of the Everest region’s mountains and horizons. How not, the region is one of the best places for trekking. A number of thousands of people every year do the Everest Base Camp Trek only. The trial becomes the busiest of all in Nepal during peak times like Autumn and Spring. So to avoid the crowd, many peace lovers opt Everest Three High Passes Trek over Everest Base Camp Trek. The latter trail is far more peaceful than the former throughout the year. There is no bad in doing the High Passes Trek as you will catch the glimpses of the Everest Base Camp in this too.

So, the beauty and adventure of the trek is not experienced by many.

It is one of the shortest or maybe easiest treks to do in Nepal. There are trekkers who have completed this trek within 4 days too. But 6 to 10 days are a must to enjoy the happenings of the trek calmly. The best part about this trek is snow-layered mountains, scenic panoramas, and green trekking trails.

Moreover, you’ll encounter beautiful people of the Annapurna area along the trail. If lucky enough, you’ll also come across several faunas of the Annapurna Conservation Area.

This easy trek is doable throughout the year. But still, Autumn and Spring are the two better times for the trek.
