Darjeeling, Sikkim & the Singalila Ridge

The adventure begins at our hotel in Delhi. You are free today to explore the city or rest after your flight; rooms may not be available until noon but it is often earlier than this. Our leader holds a trip briefing today. You need passport photographs for the various permits and checkposts, so please ensure you bring four. Stay: Hotel Bloom Karol Bagh (or similar).

We transfer to the domestic airport terminal and fly to Bagdogra.

On arrival, we join our vehicles and drive to Gangtok. The road soon leaves the plains and at Sevoke we cross the Teesta River and climb into the Doar Hills. At Rangpo, we take a break as we enter Sikkim. Border formalities take time – you need your passport and one photograph. Climbing further, we reach Gangtok, the capital of Sikkim, set at an elevation of 5,510ft (1,680m). The drive usually takes about five hours (78mi/125km) but has been known to take up to 10 hours in instances where landslides have occurred from heavy rain along the route. Your leader will advise if your journey is likely to be affected. Stay: Netuk House, Gangtok (or similar) (B/D).

Gangtok is set among the hills and, on a clear day, we can see Kanchenjunga from the hotel. We have the morning for exploration. The Mall Road is the centre of Gangtok and the nearby indoor vegetable market makes for an interesting wander. Either explore Gangtok solo or your leader can take you to see some of the sights. About an hour's walk from the hotel there is the small Enchey monastery. Overlooking the town, it was founded in 1840 by Lama Drubthob Karpo and was rebuilt in 1908 by the 10th chogyal (king) of Sikkim. From the monastery, walk back to town via the Flower Show, a small exhibition of orchids and other local flowers.

There is a handicraft centre close by, which is a government enterprise offering community training in traditional handicrafts such as carpet weaving and wood carving. After lunch, we have an hour's drive to Rumtek monastery. Founded in the mid-1700s by the 12th Karmapa, it fell into ruins. When the 16th Karmapa came from Tibet, he rebuilt the monastery as the main seat in exile of the Karmapa sect. It is the largest monastery in Sikkim and contains a golden stupa with the remains of the 16th Karmapa. A 30-minute drive brings us to Martam, a scenic Himalayan village in a quiet corner of East Sikkim. Stay: Martam Resorts (or similar) (B/D).

We spend today in the pretty village of Martam, which was known for producing butter and other dairy products (mar means butter and tem means spread). The population is about 10,000, made of Bhutia and Nepali communities. In the morning, we go for a hike around the village. We can visit the interesting Nyingma Institute, which provides education in higher Buddhist studies and philosophy to many monks. There is also another small monastery and a Krishna Mandir in the village. We return to our hotel for lunch and the afternoon is free. Stay: Martam Resorts (or similar) (B/L/D).

Leaving Sikkim, we drive to Darjeeling. The road winds all the way to the Testa River, where we enter the state of West Bengal. It then weaves back into the hills to Darjeeling. We arrive by lunchtime; this afternoon, we explore one of the most famous hill stations of the British Raj. The region originally belonged to the chogyals of Sikkim, before it was annexed by the Gurkhas. By the early 1800s, it was in the control of the British East India Company who returned it to Sikkim rule. Stumbling across Dorje Ling Monastery, situated on a quiet forested ridge, two British soldiers thought it would make a great location for a sanatorium and with the permission of the Sikkim king, a hill station was born.

Today, Darjeeling is a bustling town but the Mall still retains Victorian charm. Our stay includes a visit to the Himalayan Mountaineering Institute, where many famous Sherpa climbers trained in mountaineering skills. There are interesting displays and photographs from some of the early Everest climbs. Today's drive is 50mi (80km) and will take approximately four hours; however, there may be delays due to landslides caused by heavy rain. Your leader will advise if this is the case. Stay: Sinclairs Hotel (or similar) (B/D).

On a clear day, wake early for beautiful sunrise views of Kanchenjunga from the roof of our hotel. After breakfast, we have a 40-minute ride on the toy train to Ghoom (subject to running, see Day 13 for another opportunity if not running today). The train chugs out of Darjeeling, stopping to take on water and to allow passengers to photograph the Batasia Loop.

At Ghoom, we meet our cars and drive for around four hours to Rimbik, the trailhead of our trek at 7,500ft (2,286m). We have a 45-minute gentle uphill walk through magnificent rhododendron forests (a blaze of reds in spring) to our camp at Manedara, where we spend our first night under canvas. As we approach the village, we have stunning views of Kabru Dome and Kabru South peaks. Stay: Full-service camp – sleeping altitude: 8,040ft (2,450m) Please note: Any baggage not needed during the trek can be left at our hotel in Darjeeling until we return on Day 12. (B/L/D).

Today we start our trek with an easy trail passing small houses and fields. It is about two hours' gradual walk through beautiful forest to Shepi village. We then descend to the Gurdum Khola river, which we cross by bridge and after a steep one-hour climb to Gurdum village, we arrive at our camp for the evening. Stay: Full-service camp – sleeping altitude: 7,875ft (2,400m) (B/L/D).

It's a fairly tough but rewarding day as we finish our ascent to the Singalila Ridge. The trail climbs steeply in places until we emerge at a forest clearing. From here, it undulates through rhododendron forest to the ridgetop at Sandakhphu (11,929ft/3,636m), the highest point of our trek. On a clear day, the climb is well worth the effort as we are rewarded with a magnificent Himalayan panorama.

The views from here are truly amazing – the towering slopes of Kanchenjunga lie ahead and Everest, Lhotse and Makalu come into view in the distance. After lunch at Sandakhphu, it is a gradual walk on a rough jeep track to our camp at Chandu. Stay: Full-service camp – sleeping altitude: 11,715ft (3,570m) (B/L/D).

We are now on the Singalila Ridge, the border between Nepal and India, which means at times we are walking in each country. This is a great day for views. The trail undulates, following the ridge through chestnut, oak and silver fir trees with commanding panoramic views of the Himalaya all day. Dwarf rhododendrons and primulas colour the landscape in spring.

Tonight, we have a spectacular wild camp at Sabargam. The views from here are sublime and we hope to see a magnificent sunset and sunrise over Kanchenjunga, Everest, Lhotse and Makalu and a whole host of other Himalayan peaks. Stay: Full-service camp – sleeping altitude: 11,601ft (3,536m) (B/L/D).

We enjoy a full day of trekking along an undulating trail to the end of the ridge at Phalut, where we descend to Samaden. On a clear day, we get breathtaking views of Kanchenjunga as we continue along the ridge. The Everest range is further away but Kanchenjunga rears up over us. Phalut is at 11,810ft (3,600m) and just behind the lodge there is a viewpoint where we are surrounded by Himalayan giants. The trail down to Samaden is glorious and takes us through forests of oak, conifers, pine and rhododendrons, an explosion of colour in spring. We camp tonight in Samaden, a small settlement with excellent views. Stay: Full-service camp – sleeping altitude: 8,135ft (2,480m) (B/L/D).

Our final trek winds through a collection of small settlements (inhabited by Rais, Sherpas and Tamangs) to Ramman, where terraced fields and villages dot the landscape. We descend along a jeep track to Sri Khola for lunch, after which we cross a suspension bridge and continue for another 2hr 30min along a road, passing through more villages to Rimbik, a large Sherpa village among the forest landscapes of Singalila National Park. We stay in a small lodge with great views across the valley.

Stay: Rimbick Lodge (guest house) – sleeping altitude: 7,500ft (2,286m) Please note, the guest house is a basic home-stay property. Although all bedrooms offer attached bathrooms (including toilets), those with shower facilities are limited and some bedrooms may only provide a sink and "bucket" wash option (B/L/D).

Today we drive back to Darjeeling along a road that winds up and down ridges through picturesque landscapes. En route, we visit a tea estate and learn how this famous drink is grown and processed. We arrive in Darjeeling midafternoon and the rest of the day is free to further explore this historic hill station. Our hotel is close to the Mall, which is a great place to wander in the evening. Stay: Sinclairs Hotel (or similar) (B).

We have the morning to explore further. If we missed the ride on the toy train and Ghoom monastery, there is time this morning.

In the afternoon, we set off for the drive to Siliguri (two to three hours) where we board the overnight train to Kolkata. Train times in India change regularly, although it usually departs around 8pm or 9pm. Stay: Overnight sleeper train (B).

We arrive in Kolkata in the early hours of the morning and have the day to explore this fascinating city. Once the capital of British India, Kolkata has a turbulent past. It was central to the struggle for Indian independence and thousands of Bengali refugees came here at the start of the 1900s. It is a city of striking contrasts and the unusual sights, pungent smells and cacophony of sounds are an experience unique to India. If you would rather not navigate Kolkata alone, your leader can usually arrange a short guided city tour for you (pay locally). Stay: Hotel Peerless Inn (or similar) (B).

The adventure ends in Kolkata after breakfast. If you'd like a little more adventure, however, consider joining our five-day Golden Triangle extension. Encompassing Delhi, Jaipur and Agra, the trip is a whirlwind of culture, taking in the Taj Mahal, Red Fort of Akbar and much more (B).
