Barsey (Varsey) Rhododendron Sanctuary covers 104 km² of the Singalila Range in Soreng district, from about 2,200 m to 4,100 m. Most visitors walk 4–5 km from the road at Hilley to the Barsey ridge at about 3,000 m, best from March to May for flowers and October to December for Kangchenjunga.

Barsey, also spelled Varsey, is a protected forest on the Singalila Range at the western edge of Sikkim. It covers about 104 km², borders Nepal to the west and West Bengal to the south across the Rambong Khola, and climbs from roughly 2,200 m to 4,100 m. The state notified it as a sanctuary in 1996 to protect rhododendron, oak and bamboo forest that was under pressure from grazing and wood cutting, according to a study published in Sibbaldia, the journal of the Royal Botanic Garden Edinburgh.
Most visitors know it for one walk. From the road-head and wildlife checkpost at Hilley, at about 2,750 m, a well-trodden trail runs 4–5 km through rhododendron, oak and magnolia forest to the Barsey ridge at about 3,000 m, where a clearing called Guras Kunj has a trekkers' lodge. From March to May the trees flower red, pink and white, and on clear mornings Kangchenjunga stands over the forest to the north.
The sanctuary can also be entered from Soreng and from Dentam, but Hilley is the easiest. Okhrey, a Sherpa village 8 km below Hilley, has the most homestays. The walk suits anyone reasonably fit, including older children, but the altitude is real: walk slowly, drink water and turn back if you feel unwell. Indian visitors pay a small entry fee at Hilley; check current status before you travel.
Highlights
What to see and do
The Hilley–Barsey walk
A 4–5 km forest trail from the Hilley checkpost to the Barsey ridge, gaining about 250 m. Most people take 1.5–2 hours up and a little less down. The path is broad and well marked but rocky and muddy in places, so wear shoes with grip.
Rhododendron season
From March to May the forest flowers in waves, lower trees first and higher ones later, in red, pink, white and cream. Peak bloom varies by year and altitude; mid-March to late April is a fair bet for the lower trail. Do not pick flowers; it is prohibited inside the sanctuary.
Kangchenjunga from Guras Kunj
On clear mornings the Kangchenjunga range rises above the forest from the Barsey ridge, 8,586 m at its highest. October to December gives the clearest skies; in spring, haze and afternoon cloud are common, so reach the ridge by mid-morning.
Forest birds
The sanctuary is a BirdLife Important Bird Area. Early mornings bring mixed flocks of tits, warblers and sibias through the trees, and with luck pheasants on the trail edges. A local birding guide and binoculars make a big difference.
A night on the ridge
Guras Kunj, the trekkers' lodge on the Barsey clearing, offers basic rooms for those who want sunset and sunrise on the ridge. It has had no grid electricity or mobile signal, and food is simple. Book ahead in spring and check current status before you travel.
Okhrey's Sherpa homestays
Eight kilometres below Hilley, Okhrey is a mainly Sherpa village with many family homestays and a Nyingma monastery built in 1950. It is the best base for the walk, with warm rooms, home cooking and a short dawn drive to the trailhead.
The story of Barsey Rhododendron Sanctuary
How grazing bans brought the forest back
When Barsey was notified as a sanctuary in 1996, much of the Singalila forest on the Sikkim side was being grazed by cattle and cut for fuel and fodder. As across much of the Singalila range, herders used the high forest for seasonal grazing. A study published in Sibbaldia, the journal of the Royal Botanic Garden Edinburgh, describes how the forest department excluded grazing from the sanctuary and worked with nearby communities, including those around Hilley, Okhrey and Singling, to replace that income. Homestays in the fringe villages are part of that picture: travellers who come for the forest now bring income to the families who live beside it. The authors report forest regeneration, higher carbon stocks, springs that had dried up running again, and a rise in ecotourism during the flowering season. It is a quieter story than a legend, but a rooted one: the rhododendrons you walk under at Barsey are, in part, the result of choices made by the villagers who now cook your dinner in Okhrey.

Experiences
Hours worth planning in Barsey Rhododendron Sanctuary
Take a shared jeep from Siliguri or Jorethang towards Sombaria or Soreng, then a local jeep or reserved taxi up to Okhrey and Hilley. From Jorethang to Sombaria is about 28 km; Sombaria to Okhrey 14 km; Okhrey to Hilley 8 km. A reserved taxi Okhrey–Hilley costs about ₹600–800.
Private car
Hilley is about 50 km from Jorethang (2.5 hours), 38 km from Soreng (1.5–2 hours) and roughly 48 km plus 8 km from Rinchenpong via Soreng and Okhrey (about 2.5–3 hours). From Gangtok allow about 6 hours. A small car from Rinchenpong costs about ₹3,000–4,000 one way.
From Bagdogra / NJP
Okhrey is about 125 km from Siliguri, 5–6 hours via Sevoke, Melli and Jorethang; Hilley is 8 km further. A small car costs about ₹5,000–6,500. NH10 along the Teesta closes after monsoon slides, when cars detour via Kalimpong. Check current status before you travel.
Permits in Soreng
Indian travellers need no special permit anywhere in Soreng district. You pay Sikkim's ₹50 tourist fee, collected by your hotel or homestay and valid 30 days, and an entry ticket at the Hilley checkpost for the Barsey Rhododendron Sanctuary, about ₹50 for Indians. Foreign nationals need Sikkim's Restricted Area Permit, which since 12 January 2026 is applied for online on the e-FRRO portal after arriving in India, with approval in 24–48 hours. Foreigners pay a higher Barsey entry fee. Check current status before you travel.
Okhrey, 8 km below Hilley, has the widest choice: Sherpa family homestays such as Sherpa Lodge cost about ₹1,200–2,000 per person with all meals. At Hilley itself, a few small homestays listed by the Soreng district administration, including Barsey Residency, Lali Gurash and Royal Barsey, put you on the trail at dawn for ₹1,000–1,800. On the ridge, the Guras Kunj trekkers' lodge offers basic beds without grid power. For resort comfort, stay in Kaluk and make Barsey a long day trip.
Start walking from Hilley by 7 am to reach the ridge before cloud builds in the late morning.
Carry cash for entry fees and food; there are no ATMs beyond Soreng or Sombaria.
Wear layers: it can be 15 °C at Hilley in the sun and near freezing on the ridge after dark.
Do not pick rhododendron flowers or leave litter; both are prohibited and fines apply.
Expect leeches on the trail from June to September and carry salt or anti-leech socks if you go then.

March to May for rhododendron flowers, with mid-March to April often best on the lower trail. October to December gives the clearest views of Kangchenjunga with no flowers. Winter is cold but often clear, with occasional snow. June to September brings rain, leeches and cloud.
How long is the Hilley to Barsey walk?
About 4–5 km each way. Wikipedia gives 4 km and the Soreng district site about 5 km, depending on where you count from. Allow 1.5–2 hours up and 1–1.5 hours down, plus time on the ridge. The trail gains roughly 250 m.
What is the entry fee for Barsey Rhododendron Sanctuary?
In recent seasons, about ₹50 per day for Indians and ₹100 for foreigners, plus a small camera fee, paid at the Hilley wildlife checkpost. Fees can change, so check current status before you travel. Carry cash; card or UPI may not work at the checkpost.
Where should we stay to visit Barsey?
Okhrey, 8 km below Hilley, has the most homestays and the best food choice. Hilley has a few basic homestays at the trailhead for a dawn start. The Guras Kunj lodge on the ridge offers a basic night inside the sanctuary. Kaluk's resorts work for a long day trip.
Is Barsey in Soreng or West Sikkim?
Barsey is in Soreng district, which was part of West Sikkim until December 2021. The sanctuary's western and northern edges run along the Nepal border, and its Dentam entry approaches from the Gyalshing (West Sikkim) side. Most visitors enter from Hilley in Soreng district.
Can children do the Barsey walk?
Yes, children of about eight and above who are used to walking usually manage it well, and younger ones can be carried in parts. Go slowly because of the altitude. Do not take children under five up to sleep at Guras Kunj; stay lower in Okhrey.
Do foreigners need a special permit for Barsey?
Foreign nationals need Sikkim's Restricted Area Permit, applied for online on the e-FRRO portal since January 2026, plus the normal sanctuary entry ticket at Hilley. We are not aware of an extra protected-area permit for Barsey, but check current status before you travel.
Is there snow at Barsey?
Sometimes, from about December to February, on the ridge and higher parts of the sanctuary. Snow is not reliable year to year. When it falls, the trail can be icy, so carry shoes with good grip and ask in Okhrey about conditions before you start.
Can we do Barsey as a day trip from Pelling or Rinchenpong?
From Rinchenpong or Kaluk, yes, as a long day: about 2.5–3 hours each way by car to Hilley plus 4–5 hours on foot. From Pelling it is about 90 km to Hilley, too long for comfort. We suggest one night in Okhrey instead.
