Overview

The Helambu Trek starts at the edge of the Kathmandu Valley and needs no flight: a short drive to Sundarijal and you are walking. The route climbs through Shivapuri-Nagarjun National Park to Chisapani, follows a long forested ridge north via Kutumsang to its high point at Tharepati, then drops into the Melamchi valley and the villages of Melamchigaon, Tarkeghyang and Sermathang before finishing at Melamchi Bazaar.

Helambu is the homeland of the Hyolmo (Yolmo) people, Tibetan Buddhist communities with their own language and some of the region's oldest monasteries, at Tarkeghyang and Melamchigaon. Their stone houses, prayer walls and apple orchards give the second half of the trek its character, and homestays are available in several villages.

At under 3,700 m, altitude is rarely a problem, and the trek works in the shoulder months and in winter when higher routes are cold or snowbound. The trade-off is views: the Langtang, Gauri Shankar and Jugal ranges show best from the ridge around Tharepati and on clear mornings in autumn.

It suits trekkers with a week to spare, families, and anyone wanting a first teahouse trek close to Kathmandu. Licence-verified guides you contact directly can suggest how to shorten or extend the loop.

🌟 Trail Highlights

Permits & costs

Permit & park fees
NPR 6,000 per person (β‰ˆ US$39)
Guide day rates
$25–$35 per day, set by the guides below
  • Shivapuri-Nagarjun National Park (NPR 1,000, about USD 6): collected at Sundarijal, where the first morning's climb enters the park's forest on the way to Chisapani.
  • Langtang National Park (NPR 3,000, about USD 19): the upper Helambu ridge around Tharepati lies inside the park, so you need its permit even though Helambu feels like village country.
  • TIMS card (NPR 2,000, about USD 13): Helambu is on the Nepal Tourism Board's guide-and-TIMS list, so your registered agency arranges the card when it assigns your licensed guide.
  • Park and TIMS rates are revised from time to time, so check the current figures with your agency before setting off.

Getting there & back

Helambu is the trek you can start from a Kathmandu taxi: Sundarijal is about 45 minutes from the city centre, so there is no flight and no long bus day. The loop finishes at Melamchi Bazaar (Melamchi Pul), 3–4 hours back to Kathmandu by bus or jeep. The Melamchi road is often damaged by monsoon floods, so check it before you go; some versions finish at Timbu or other Sindhupalchok villages instead.

Helambu Trek FAQs

How difficult is the Helambu Trek?

It is an easy to moderate trek. Days are 4–7 hours with plenty of stone steps and some steep descents, but the high point is only about 3,640 m. Good general fitness is enough, and it is a common first trek in Nepal.

Is altitude sickness a concern?

Rarely. Tharepati, the highest night, is around 3,640 m, so most people are fine, but drink plenty and tell your guide if you get a headache that doesn't go away. If you plan to continue to Gosainkunda from Tharepati, that route goes much higher and needs more care.

Do I need a guide?

Yes. Since 1 April 2023 foreign trekkers in Nepal's national parks must trek with a licensed guide arranged through a registered agency, and upper Helambu is inside Langtang National Park. A local guide also helps with homestays and the many trail junctions.

What permits do I need?

The Langtang National Park permit and, for the usual Sundarijal start, the Shivapuri-Nagarjun National Park fee, NPR 6,000 in total with a TIMS card (about USD 38). TIMS requirements are reported inconsistently in 2026, so confirm with your agency.

When is the best time to go?

October to December and March to May are best. Because it stays below 3,700 m, Helambu is also walkable in winter, when nights are cold but skies are often clear. The monsoon (June to September) brings leeches in the forests and landslide risk on the roads.

Who are the Hyolmo people?

The Hyolmo (or Yolmo) are the Tibetan Buddhist community of Helambu, with their own language and traditions. Villages such as Melamchigaon and Tarkeghyang have old monasteries, and several families run homestays where you can stay with them.

What is accommodation like?

A mix of simple teahouses and village homestays. Rooms are basic but clean, meals are home-cooked, and most places offer phone charging; mobile signal is available in many villages.
