Aja Ney

Aja Ney is one of the great Bhutanese pilgrimages, and it is not a sightseeing walk. It is a cluster of sacred sites around a rock cave in northern Mongar at 2,400 m to 3,500 m, about six hours on foot beyond the road head as it stood in 2023 — and it is open only from about October to March, on the last window anybody published. If you want to do it, tell us early.

What is up there?

A cave with a hundred imprints of the syllable “Aa” on the rock, held to have been left by Guru Rinpoche. That is what the name means: aja, a hundred As. Pilgrims who see them are said to be cleansed of past misdeeds, and every account of the place agrees on the number, which is rarer than you would think.

Around the cave there is more: the Aja Menchu, a spring believed to cure eighteen different ailments and which people come specifically to bathe in, and a scatter of other sacred sites across the hillside. Iron ladders are fixed between them — thirty-four of them, put in by the wildlife sanctuary in 2018 to replace wooden ones, which is the single change that turned a week-long pilgrimage into something that can be done in a few days.

And there are people living there. Aja is a village of about thirty-four households as well as a shrine; an eighty-kilowatt solar array was switched on there at the end of 2022 — the first of its kind at Aja, and the end of doing the evenings in the dark. Forestry records counted over a thousand pilgrims in 2019, the last year anybody published a figure.

Why do Bhutanese come here specifically?

Because of the mantra.

Three sacred sites in Bhutan carry the three syllables of Om Ah HungOmba Ney in Trashi Yangtse, Aja Ney here, and Hungrel in Paro. Between them they spell it out, and doing all three is a pilgrimage that crosses the country. It is the reason a hillside in Mongar draws people from Haa.

When can you go?

Roughly October to March, and not otherwise — that is the window as it was last published, in 2019.

For the rest of the year the mountain is closed under Ladam — the traditional practice of shutting a mountain to human activity for part of the year, propitiating the deity who lives there, and keeping everyone off until it is opened again. Different sites keep different windows; the trek to Dangling Tsho in Trashigang, for instance, is closed in almost exactly the opposite half of the year.

Ladam is not a formality and it is not something an operator can arrange around. An itinerary that falls outside the October–March window cannot include Aja Ney, and anyone offering it in the closed months is selling something they cannot deliver.

How hard is it?

Hard enough that it should be planned as its own trip rather than added to one.

As of 2023 the farm road reached Yarab, and from there it is about 13 km and six hours on foot to Aja. That number has moved twice in a decade and will move again — the whole pilgrimage once took roughly a week, was down to three days by 2019, and the road has been advancing since. Anything you read describing a two-day walk is measuring from an older, further road head. Ask us what the walk actually is in the season you are travelling.

The ney sits inside the core zone of Bumdeling Wildlife Sanctuary, the same protected landscape that reaches across into Trashi Yangtse and Lhuentse — Mongar is its third district, and Aja is where Mongar’s share of it is.

Should you do it?

Only if the walk is the point. What is here is a place devout Bhutanese hope to reach once in their lives, and a hillside full of people who have made the same walk for the same reason — not a viewpoint you drive to. What is actually on the ground beyond the sacred sites and the thirty-four households, nobody publishes, so ask us rather than picture it.

If that is what you are after, there is nothing else quite like it. Talk to us before you build the itinerary around it — the season is narrow, the walk is real, and both ends of it need arranging.

Frequently asked questions

How long does it take to get to Aja Ney?

About six hours on foot from Yarab, where the farm road ended as of 2023, 13 km away. That has changed twice in a decade — the full pilgrimage once took about a week, was reported down to three days by 2019, and the road has been creeping closer since. Older accounts describing a two-day walk are measuring from a further road head. Ask us what it is now, because this is a figure that keeps moving.

When is Aja Ney open?

Roughly October to March — that window was last published in 2019, so check with us before you build a trip around it. From about April to September it is closed under Ladam — the traditional closing of a mountain to human activity, which several Bhutanese sites observe on their own calendars. It is not a formality and it is not negotiable, so an itinerary falling outside the October–March window cannot include it.

What is at Aja Ney?

A rock cave carrying a hundred imprints of the syllable "Aa", left by Guru Rinpoche — which is what the name says, aja, a hundred As. There is also the Aja Menchu, a spring held to cure eighteen ailments, and a scatter of other sacred sites around the hillside linked by fixed iron ladders. Around thirty-four households live up there.

What is the Om Ah Hung pilgrimage?

Three sacred sites whose names begin with the syllables of the mantra — Omba Ney in Trashi Yangtse, Aja Ney here in Mongar, and Hungrel in Paro. Walking all three completes Om Ah Hung, and it is the reason Bhutanese pilgrims travel the length of the country to a hillside in Mongar.
