**Please note that this trip is now completed, and we are currently awaiting confirmation of the 2019 festival dates before deciding whether to run the trip again next year. A brief photo journal of this trip can be viewed in our Adventure Diary **

First things first. This is a trekking adventure that, as far as we know, is exclusive to Whistling Arrow. It is only made possible by our longstanding relationship with the villagers of Olanchung Gola, a traditional weaving community in the wild Tibetan borderlands of northeastern Nepal, tucked away between the world's two most easterly 8000m+ peaks, Kanchenjunga and Makalu. The trip is also not for everyone. The unique expedition will cross the exposed 5160m Lumbasumba La, explore one of the most remote historical gateways into southern Tibet and traverse back to the lush lower Arun Valley via both the seldom-trekked Thang La Byanjang, and the remote sherpa village of Topkegola.

 It is a wilderness adventure designed for relatively experienced and intrepid trekkers who are keen to avoid the crowds that clog the well-trodden routes to Everest and Annapurna. But that's just the half of it. The village and surrounding peaks shelter a number of cultural gems. Foremost among them is Deki Chholing, a 450 year old Nyingma-sect monastery that houses a treasure trove of ancient Buddhist texts and hosts an annual Tibetan Buddhist festival, in the Dzogchen 'Northern Treasures' tradition. So, fully immersing ourselves in the festivities, we will also participate in fascinating tantric rituals, experience fierce-looking masked deities and witness the secretive 'Black Hat' Cham dance, usually only performed by monks, but here, because of the small size of the gompa, lay people are also involved.

Last but not least, we also plan to trek up to the snowy abode of the snow leopard (where up to eight cats are believed to roam), explore a sacred lake never before visited by outsiders, and access the trailhead at Olanchung Gola via a thrilling, privately chartered helicopter flight across the Himalayas. All this, within a relatively compact 16 day trip.

We will supply all camping equipment. Please refer to our typical kit list for a guide to what else to bring.­

First Aid ­
