How Difficult is the Bali Pass Trek?

The Bali Pass Trek doesn’t need an introduction in trekking circles. For years, it has quietly held a place of reverence among experienced trekkers — those who crave the thrill of a true high-altitude adventure, away from the commercial trail.

But if you’re hearing about it for the first time, let us walk you through it.

This is not just a trek. It’s a spectacular pass crossing that takes you from the lush, secluded valleys of Har Ki Dun and Ruinsara to the spiritual town of Yamunotri. And standing on Bali Pass — at a staggering altitude of 16,207 ft — you experience something that few Himalayan treks in India can offer: the sharp sting of challenge wrapped in some of the most breathtaking views of the Garhwal Himalayas.

Watch this quick video to get a good overview of the difficulty of the trek. But don’t stop there — the article dives much deeper. I’d definitely recommend giving it a read. Towards the end, you’ll also find answers to some of the most commonly asked questions about the trek

What Makes Bali Pass So Special

When Arjun Majumdar, the founder of Indiahikes, first spoke about Bali Pass, there was a glint in his eye.

“It’s not Bali Pass for many,” he said. “It feels like a summit.”

And it truly does.

The Bali Pass trek route is unlike any other. As you climb steep snow ridges toward the pass, the trail demands every ounce of your attention — not just because of the gradient, but because of the raw beauty that surrounds you.

Walking along narrow ridgelines with deep valleys falling away on either side is a surreal experience. And when you finally reach the pass, the 360-degree views are utterly rewarding. Behind you, the Bandarpunch ranges rise in full glory. Bandarpunch I, Bandarpunch II, and Swargarohini stand tall — so close you forget the effort it took to reach there.

The Approach: A Trek in Itself

What many trekkers don’t realise is that even before reaching the pass, the trail gives you a full-fledged experience. The valley of Har Ki Dun is a dreamscape — dense forests, wildflowers, ancient Himalayan villages, alpine meadows, and quiet rivers.

The detour to Ruinsara Tal adds another layer of magic. It’s serene and still, reflecting the mountains that cradle it.

Even if the pass crossing becomes unfeasible due to snow or weather, reaching the advanced base camp at Upper Dhamni feels like completing a trek in itself. That’s the kind of depth and beauty this trail holds.

How Difficult is the Bali Pass Trek?

Let’s not sugar-coat this — Bali Pass Trek is not for beginners.

At 16,207 ft, the oxygen level is roughly 60% of what you're used to at sea level. That means your body has to work much harder to move, climb, and even sleep.

What makes Bali Pass trekking especially tricky is a narrow ridge section just after the pass, as you descend towards Yamunotri. It’s only about 100–150 metres long, but the trail is exposed on both sides — one of the most adrenaline-inducing sections of the trek. On snowy or icy terrain, teams may need to rope up for safety.

But it’s not just one day that’s tough — the trek constantly tests your endurance.

Let’s break it down further:

1. Steep Climbs and Technical Descents

After Ruinsara Tal, the trail gains altitude rapidly. The final climb to the pass is steep and often covered in snow, especially during the pre-monsoon season (May–June). Microspikes or crampons are usually required here.

The descent from the pass is even more demanding — you lose nearly 3,500 ft of altitude on a combination of scree, snow, and rocky sections. The route is narrow, slippery, and technical. Focus and surefootedness are crucial.

2. High Altitude and Acclimatisation

The Bali Pass trek climbs up to 16,207 ft, which puts it firmly in the high-altitude zone. You begin ascending steeply after Ruinsara Tal (11,715 ft), and spend the next few days at elevations where the oxygen level drops to nearly 60% of sea level.

This makes you more prone to altitude-related issues like headaches, fatigue, or mild nausea. If ignored, these can escalate into serious conditions like AMS.

At altitudes above 10,000 ft, the chances of being hit by Acute Mountain Sickness are real. Altitude sickness can happen to anybody - first-time trekkers as well as experienced trekkers. Fitness helps in making your trek easier. But do not forget that even a fit person climbing too high too soon runs an equal risk of developing AMS.

3. Unpredictable Weather

Even in the best time for Bali Pass trek — which is typically May–June and September–October — the weather near the pass can turn rapidly. Snowfall, whiteouts, or hail are not uncommon.

During monsoon months, the trail becomes risky with landslides and slippery rocks, making the Bali Pass trek best time an important consideration for your safety.

4. No Exit Routes After a Certain Point

Once you cross Ruinsara Tal, the Bali Pass trek becomes a committed trail — meaning there are no quick exit options available. If you're feeling unwell or there's a medical emergency, evacuation becomes challenging and time-consuming.

Before crossing the pass, your only option is to retrace your steps to Taluka, and eventually exit via Kotgaon. After the pass, your exit is via Lower Dhamni to Janakichatti.

But both these exits involve long descents on foot, often through difficult terrain. After reaching Taluka or Janakichatti, you'll still need to hire a jeep — to Purola from Taluka or to Rajgarhi from Janakichatti — to get to the nearest medical facility. The roads in this region are known to be in poor condition, and evacuation can easily take up to 24 hours.

This remoteness adds a serious layer to the trek's difficulty. It’s essential to listen to your body, report any early symptoms, and never push through discomfort, especially after Ruinsara.

Is the Bali Pass Trek for You?

The Bali Pass Trek is not meant for everyone — and that’s what makes it stand out.

At over 16,207 ft, with steep ascents, exposed ridgelines, and technical descents, this is a trail that demands the best of you — physically, mentally, and emotionally. It requires prior experience in high-altitude trekking, strong fitness, and a willingness to embrace the unexpected. Each day on this 55 km trail brings significant altitude gain, long walking hours, and terrain that tests your focus — especially on the summit day.

But if you’re someone who enjoys raw, remote landscapes and seeks a deep sense of personal accomplishment, few trails in India will match what Bali Pass offers. The silence, the solitude, the sheer scale of the Himalayas — it all adds up to a once-in-a-lifetime experience.

This is not just a trek. It’s a high-stakes, high-reward adventure. One that stays with you long after it’s over — not just because of the views, but because you know exactly what it took to stand there.
