I’ll never forget the moment I crested Larkya La Pass at 5,106 meters and saw what looked like a graveyard of plastic bottles glinting in the morning sun. Here I was, standing at one of the most spectacular viewpoints in the Himalayas, and instead of feeling pure awe, my heart sank. That was three years ago, and it changed how I approach every trek since.
The Manaslu Circuit remains one of Nepal’s most pristine trekking routes, but it won’t stay that way without our help. Having guided dozens of groups through these remote valleys beneath the world’s eighth-highest peak, I’ve witnessed both the magic of untouched wilderness and the creeping impact of careless trekking. This 177-kilometer journey through diverse landscapes—from steamy subtropical forests to wind-scoured passes—offers something increasingly rare: an authentic Himalayan experience away from crowds.
But here’s the thing: with more trekkers discovering this hidden gem each season, we’re at a crossroads. The fragile alpine environment that shelters snow leopards and red pandas needs our protection now more than ever. If you’re planning your own adventure (and I highly recommend checking out a detailed Manaslu Circuit Trek itinerary to understand the route), let me share what I’ve learned about trekking responsibly in this spectacular region.

Why Eco-Friendly Trekking Matters in Manaslu
Last spring, I met an elderly woman in Samagaon who showed me a photo from 1995—crystal-clear streams where her grandchildren played. Today, those same streams carry soap suds and toilet paper during peak season. Her story isn’t unique. The Manaslu Conservation Area’s 1,663 square kilometers face mounting pressure from our footsteps.
I’ve watched yaks change their grazing patterns to avoid crowded trails. I’ve seen sacred juniper groves stripped for illegal campfires. The glacial rivers that provide water to thousands of families downstream now carry microplastics from our gear. It breaks my heart because I know we can do better.
The cultural impact hits just as hard. The Nubri and Tsum peoples have welcomed trekkers for generations, but irresponsible tourism threatens their way of life. When trekkers barge into monasteries wearing shoes or leave trash at sacred sites, it’s not just disrespectful—it erodes the very culture we came to experience. These aren’t just statistics or abstract concepts; they’re real consequences I witness every season.
Understanding the “Leave No Trace” Principles
You know what changed my approach to sustainable trekking in Nepal? A simple conversation with a porter named Pemba, who asked me, “Would you throw this candy wrapper in your mother’s garden?” His question perfectly captured the Leave No Trace philosophy.
Let me break down these seven principles with real examples from the trail. Planning ahead saved my group last October when unexpected snow hit—we had proper gear and knew alternative routes. Traveling on durable surfaces means staying on the main trail even when it’s muddy. I’ve seen too many “shortcuts” turn into erosion scars. Disposing waste properly isn’t glamorous, but it’s crucial. Above Samdo, I carry a trowel for cat holes and pack out everything else—yes, everything.
Leaving what you find can be tough. Those prayer stones are beautiful, but they belong here. Minimizing campfire impacts means using your stove even when you’re craving that campfire ambiance. Respecting wildlife gave me my best memory: watching a Himalayan tahr family because I stayed still and quiet. Being considerate means stepping aside for uphill trekkers and keeping voices low near villages—a simple courtesy that goes a long way.
How to Practice Sustainable Trekking in Manaslu
Here’s my practical guide for responsible trekking in Nepal, learned through plenty of trial and error:
- Ditch the plastic bottles completely. I carry a Steripen and haven’t bought bottled water in years. Most teahouses between Machha Khola and Dharamsala now offer filtered water for refills. Your reusable bottle becomes your best friend.
- Choose your lodges wisely. I always stay at places like Buddha Lodge in Lho, where they compost waste and use solar panels. These eco lodges in Manaslu might cost a few rupees more, but they’re investing in the future.
- Hire local, always. My friend Tenzin from Sama village knows every bird call, every mountain legend. Local guides don’t just show you the trail—they share their home with you.
- Respect the sacred. I learned this the hard way when I accidentally pointed my feet toward a shrine. Now I always ask before photographing religious sites and remove my shoes without being asked.
- Pack like you’re visiting your grandmother’s house. Would you leave trash there? I bring ziplock bags for waste, use biodegradable soap, and even carry out orange peels (they take years to decompose at altitude).
Supporting Local Communities Along the Trek
Want to know the best dal bhat on the entire circuit? Ask for Ama’s special at the family-run teahouse in Sho. Supporting community-based tourism in Nepal isn’t just about feeling good—it creates real change. That money you spend on locally made raksi or hand-knitted mittens goes directly to families who then have an incentive to protect their environment.
I’ve watched villages transform when tourism money stays local. In Prok, tourism income funded a new school. In Bihi, it’s supporting snow leopard conservation. When you buy that yak wool blanket directly from the weaver (not from Kathmandu shops claiming “authentic village crafts”), you’re voting for sustainable development with your rupees.
My Nepali is terrible, but even my butchered “Namaste” and “Dhanyabad” bring smiles. Last month, an old man in Tilije spent an hour teaching me to count in the local dialect—pa riceless cultural exchange that no package tour can replicate.
Eco-Friendly Gear & Packing Tips
After fifteen Manaslu circuits, here’s my tried-and-tested gear list for plastic-free trekking in Nepal:
- Water purification: SteriPen or Sawyer filter—game changers that eliminate hundreds of plastic bottles
• Dr. Bronner’s biodegradable soap: One small bottle for everything from dishes to shampoo
• Solar charger: The Anker PowerPort works even in cloudy weather
• Merino wool everything: Naturally antimicrobial, so less washing is needed
• Silicone food containers: Lightweight, packable, and perfect for takeaway meals
• Cloth shopping bag: Essential for market visits and carrying snacks
I learned to buy quality once rather than cheap repeatedly. That second-hand down jacket from Thamel? Still going strong after five years. Renting crampons and ice axes makes more sense than buying for occasional use. These choices minimize trekking waste while saving money—win-win.
Final Thoughts: Protecting Manaslu for the Future
Three weeks ago, I returned to Larkya La Pass—the place where plastic bottles once made me despair. This time, it was pristine. A group of local youth had organized a cleanup, and trekkers were actually carrying out their trash. I nearly cried with relief and hope.
Eco-friendly trekking in the Manaslu Circuit isn’t about being perfect—it’s about being mindful. Every time you refill your water bottle, choose a local guide, or pack out your trash, you’re part of the solution. I’ve seen how collective small actions create massive change.
My challenge to you: Be the trekker who inspires others. When someone sees you picking up trash that isn’t yours or refusing plastic bags, it plants a seed. The future of these mountains depends on us making responsible trekking in Nepal the norm, not the exception.
The Manaslu Circuit gave me life-changing experiences, lifelong friends, and a deep connection to the Himalayas. The least we can do is ensure future trekkers and local communities can say the same. Pack your conscience along with your gear, and let’s keep this incredible place wild and beautiful for generations to come.
