Hilley-Singalila Round Trek

     If you only have time for one trek in Sikkim, this would be it.

     A combo of the Phoktey Dara and Goechala treks, this route is a showcase of Sikkim’s natural splendour at its best. Experience the Himalayan state’s gamut of microclimates, diverse forest zones, motley flora and fauna, lofty passes and perpetual sightings of rugged, snow-clad mountains gracing the Sikkim skyline. Wildlife sightings, from Sikkim’s official bird - blood pheasant (Ithaginis cruentus) and Himalayan paradise flycatcher (Terpsiphone paradisi leucogaster) to the Himalayan musk deer (Moschus leucogaster) and endangered red panda (Ailurus fulgens), the State animal of Sikkim, are a possibility on this trek.

     A high fitness level is a prerequisite for trekkers who embark on this long and arduous but rewarding route.

Rise before dawn to hike up to Phoktey Dara viewpoint to catch the sun rising over the mighty Kanchendzonga massif. After savouring the jaw-dropping view, head back to Khalijhar camp for breakfast. After breakfast, we continue our journey on the Singalila Ridge to Dhoor. On a clear day from the ridge, you will see the stunning panorama of the “Sleeping Buddha” formation with four of the world’s highest peaks: Mt Everest, Mt Kanchendzonga, Mt Lhotse and Mt Makalu. The Ridge forms a natural border between Nepal and Sikkim. Overnight at Dhoor.


Day 06: Dhoor - Parey Megu (3965m); 5 to 6 hours

Due to the Ridge’s undulating terrains, we go through several descents and ascents and over a couple of passes before we set up camp at a sheep herders’ settlement. Overnight at Parey Megu, also known as Meguthang. 


Day 07: Parey Megu - Lampokhari (4100m); 5 to 6 hours

We continue footslogging uphill to a vast valley to get a close-up view of the Kabru massif. Made up of a group of peaks ranging from 6585m (Kabru Dome) to 7395m (Kabru III), the massif extends south from Khangchendzonga on the Singalila Range and boasts the southernmost 7,000-m peaks in the world. A further two hours’ hike takes us to the banks of Lampokhari Lake, a campsite with jaw-dropping views of Everest and the Khumbu region in the far-flung distance. 


Day 08: Lampokhari - Gomathang (3850m); 5 to 6 hours

Entering the alpine zone, we ascend higher and reach Dafeybhir La (4530m), known as the Pass of the Pheasant. The vista from Dafeybhir travels the length of Sikkim, and goes as far as Tibet and Bhutan. A steep descent takes us to the Gomathang campsite situated by the river.

Day 11: Dzongri - Thangshing (3800m); 4 to 5 hours

The trail from Dzongri climbs up along the banks of the river. After topping the hill, the trail plunges into the valley and crosses a bridge over the Prek Chu river. From late May till June, this trail is lined with rhododendron blossoms. An hour’s climb from the bridge, we reach Thangsing valley, located below the slopes of Pandim. Thangsing offers a panoramic view of the surrounding peaks. Overnight in Thangsing.

Day 12: Thangsing - Lamune (4300m); 6km; 3 hrs

An early start from Thangsing, the trail climbs gently up the valley for about an hour before we reach Onglathang where you’ll spot the south face of Khangchendzonga. The trail skirts a series of moraines and climbs steeply to Lake Samiti (4500m). We will rest at Samiti before continuing to Lamune campsite.


Day 13: Lamune - Goechala (4950m) - Thangsing; 7-9 hours

This is the longest and most challenging day of the trip, due to the high altitude and rough terrain. To catch the sunrise at Goechala viewpoint, we try to set out from campsite a couple of hours before sunrise. After a rough scramble over rocks and boulders, dragging our feet across moraines and steep ridge, we’ll arrive at Goechala. Overlooking the Talung valley, the pass is formed by depression between Pandim and the Kabru spurs. Savour the up-close view of the south face of Khangchendzonga. After the surreal experience, we descend to Thangsing to camp overnight. 


Day 14: Thangsing - Tshoka (2950m); 6-7 hours
