Overview of the Khopra Danda Trek Route

The trek begins in Kathmandu, the cultural capital of Nepal, before driving to the beautiful lakeside city of Pokhara, which is the gateway to the Annapurna trekking region. From Pokhara, the journey continues to Beni and Galeshwor, where the trekking adventure officially begins.

The route follows the Mohare Danda Community Trek, passing through traditional villages such as Baskharka and Nangi, where travelers can experience local culture and community-based tourism. The trail gradually climbs through lush forests to reach the spectacular ridge of Mohare Danda, offering stunning views of the Annapurna and Dhaulagiri ranges.

From Mohare Danda, the trail joins the classic Ghorepani and Poon Hill route, allowing trekkers to witness one of the most famous sunrise views in Nepal. After visiting Poon Hill, the trek continues to the quiet village of Swanta, leading toward the remote and breathtaking ridge of Khopra Danda.

At Khopra Ridge, trekkers enjoy incredible close-up views of Dhaulagiri (8,167m) and Annapurna South. A highlight of the journey is the challenging day hike to Khayer Lake, a sacred alpine lake located at an altitude of about 4,500 meters. This remote location offers one of the most spectacular high-altitude landscapes in the Annapurna region.

The trek continues along peaceful mountain trails to Dobato, from where trekkers hike to the hidden Muldai Viewpoint, a less crowded but equally beautiful alternative to Poon Hill. After enjoying the sunrise views, the trail descends through rhododendron forests to Chuile and Chhomrong, traditional Gurung villages known for their stunning mountain scenery.

The final section of the trek passes through Landruk and Pothana, charming villages located inside the Annapurna Conservation Area, before returning to Pokhara. After a relaxing day in Pokhara, travelers drive back to Kathmandu to conclude this unforgettable Himalayan adventure.

Why Choose the Khopra Danda and Mohare Danda Trek?

The Khopra Danda Trek with Mohare Danda offers something truly special compared to many other trekking routes in Nepal. While famous routes like Everest Base Camp or Annapurna Base Camp attract large numbers of trekkers, this trail provides a quieter and more authentic Himalayan experience.

Another unique feature of this trek is the dramatic change in landscapes. The journey begins in lush green valleys and terraced farmland before gradually ascending through rhododendron forests and alpine ridges. As you gain altitude, the views open up to reveal massive Himalayan peaks dominating the horizon.

If you love photography, nature, and cultural experiences, this trek is an excellent choice.
