The walk in brief
Barsey (also spelt Varsey) Rhododendron Sanctuary covers about 104 sq km of the Singalila Range in Soreng district, running from about 2,200 m to 4,100 m, with Nepal on its western edge and West Bengal to the south across the Rambong Khola. A paper in Sibbaldia, the Royal Botanic Garden Edinburgh's horticulture journal, describes it as protecting a high diversity of rhododendrons, oaks and bamboos; sources differ on when it was notified, with dates from 1996 to 2004 quoted.
The classic way in is from Hilley, where the road ends at a forest check post. From there a wide, stone-edged trail climbs gently through rhododendron, oak and magnolia forest to a clearing at Barsey, about 4 km away. On a clear morning the Kangchenjunga massif fills the northern skyline from the top. Wikipedia lists three entry points, Hilley, Dentam and Soreng; the other two are long, steep day trails better done with a local guide.
Most walkers base themselves at Okhrey, a Sherpa village about 10 km and 30 minutes below Hilley by road, walk up in the morning, have tea or lunch at the top and are back at the car by early afternoon.
Grading, altitude and time
We grade the Hilley to Barsey walk as easy to moderate. The trail is broad and well used, with a few rocky or muddy patches and some short steeper pulls, but no exposure and no scrambling. The height gain is roughly 270 m net, with ups and downs along the way. Anyone who can walk 8 km on hilly ground at an easy pace can do it; children of about eight and over usually manage well.
The altitude is moderate rather than high. If you have come straight from the plains, you may feel breathless on the climbs and get a mild headache; walk slowly, drink water and do not rush. Sleeping at Okhrey (about 2,200 m) the night before helps. People with heart or lung conditions should talk to their doctor before going above 2,500 m.

When the rhododendrons bloom
Rhododendrons do not all flower at once. They open from the bottom of the hill upwards, and each species has its own window, so the colour at Barsey moves through the spring. The Botanical Survey of India's 2022 book Rhododendrons of Sikkim and Darjeeling Himalaya records Lady Dalhousie's rhododendron (R. dalhousieae) at Barsey, flowering in April and May, and notes that the red form of R. cinnabarinum is common along the Singalila ridge.
As a rule of thumb, the tree rhododendron (R. arboreum, Lali Gurans in Nepali) colours the lower slopes around Okhrey from late February and March. The Hilley to Barsey stretch is usually at its best from the last week of March to the last week of April, with pinks, reds and whites together. By May the lower trees have dropped their flowers, but higher species are still open. A late frost or a dry winter can shift the peak by two weeks either way, so we ask homestays in Okhrey for a bloom report before we confirm dates.
Outside the flowering season the walk is still worth doing. October to December brings the clearest mountain views of the year. January and February can bring snow to Hilley and Barsey, which is lovely but icy underfoot. From June to September it rains most days, the forest is full of leeches and views are rare.
- Late February to mid-March: tree rhododendrons at lower levels, cold mornings
- Late March to late April: peak bloom on the Hilley to Barsey trail, busiest weeks
- May: higher species, warmer days, haze more likely
- October to December: no flowers, best Kangchenjunga views
- January and February: possible snow, check road to Hilley
- June to September: monsoon, leeches, rarely worth it
We turn this into a priced, day-by-day plan for your dates.
Getting to Okhrey and Hilley
From NJP station or Bagdogra airport, the road follows the Teesta on NH10 to Melli, crosses into Sikkim, and climbs the Rangeet valley to Jorethang. From there it goes up through Sombaria to Okhrey and on to Hilley. By private car NJP to Okhrey is about 130 km and 5–6 hours. In the monsoon NH10 closes after slides; drivers then use the Darjeeling road down to Jorethang, which adds one to two hours.
By shared jeep, go from Siliguri to Jorethang (3–3.5 hours) and on to Sombaria, then reserve a local car for the last stretch to Okhrey, as shared vehicles above Sombaria are rare. From Pelling the drive runs via Dentam to Hilley, roughly 75 km and 3–3.5 hours, so it is possible to do the walk as a long day trip from Pelling, but it is far more relaxed to sleep in Okhrey the night before.
What you will see on the trail
Beyond the flowers, the walk is a good introduction to a temperate Himalayan forest. Mossy oaks and magnolias stand between the rhododendrons, with ferns and orchids growing on their branches, and bamboo thickets in the damper hollows. Early morning is the best time for birds: laughingthrushes, sibias, tits and finches move through the canopy, and keen birders come for the sanctuary's high-altitude species. Walk quietly and you will hear far more than you see. Near the top the forest opens out, and on a clear day the snow peaks of the Kangchenjunga range line up to the north.
What the day costs
The walk itself is nearly free; the costs are getting to Hilley and the sanctuary fee. Shared vehicles to Hilley are rare, so most people hire a car from Okhrey that waits while they walk. These are indicative 2026 figures, per group unless marked; check current status before you travel.
| Item | Indicative cost |
|---|---|
| Car Okhrey to Hilley and back, with waiting | ≈ ₹1,200–1,800 per car |
| Sanctuary entry at Hilley | ≈ ₹50 Indians, ₹100 foreigners, per day |
| Camera fee | extra, ask at the check post |
| Local guide (optional) | ≈ ₹1,000–1,500 per day |
| Tea or simple lunch at the top, when open | ≈ ₹100–300 per person |
| Homestay in Okhrey with meals | ≈ ₹1,300–2,200 per person a night |
Staying overnight at Barsey
A night at the top gives you sunset and sunrise over Kangchenjunga with almost nobody around. There has long been a trekkers' hut in the Barsey clearing, known as Guras Kunj, but it has run on and off and its tariff and condition change. Camping needs permission from the forest department. We confirm what is open before offering an overnight, and most of our guests sleep at Okhrey or in a homestay near Hilley instead.
If you do stay up, bring a warm sleeping layer even in April: nights at 3,000 m fall close to freezing. Carry a torch, and take all rubbish back down with you.
Rules and good manners in the sanctuary
Barsey is a protected area. Picking flowers or breaking branches is prohibited, and the forest staff do check bags at busy times. Stay on the trail, do not play music, and keep voices down near the top where birdwatchers are often working; Barsey is listed by BirdLife International as an Important Bird Area. Plastic is discouraged: carry a refillable bottle. Foreign nationals need Sikkim's Restricted Area Permit, which since January 2026 is applied for online on the e-FRRO portal; there is no extra protected-area permit for Barsey.
- Start walking by 8 am: clouds often roll in by late morning
- Wear proper walking shoes; the trail is muddy after rain
- Pack a warm layer, rain jacket, water and a snack
- Keep the entry receipt until you leave
- Leave no litter and pick no flowers
Rules, fees, fares and road status change often. Check current status before you travel.
