Trekking Permit Requirements, Altitude Sickness Prevention, and Holy Cow Laws: A Practical Guide to Nepal

Nepal is a place that changes you. I still remember the first time I stepped out of Tribhuvan International Airport into the chaotic, dusty air of Kathmandu. The smell of incense, the honking of tiny Maruti Suzuki taxis, and the backdrop of mountains—it is a sensory overload. But beyond the majestic peaks of the Himalayas and the ancient temples, Nepal is a land of unspoken rules and strict laws that can catch even seasoned travelers off guard.

If you are planning your first trip to this beautiful Himalayan nation, you will want to read this first. I have compiled the essential realities, permits, transit hacks, and cultural rules so you do not make the same mistakes I did.

The Sacred Cow Law, Stupa Etiquette & Pressed Palms

Let’s talk about the culture because Nepal is deeply spiritual. When you greet locals, do not just wave. Press your palms together near your chest and say a warm “Namaste”. It means “I bow to the divine in you,” and it goes a long way in showing respect.

As you wander through Kathmandu or Pokhara, you will likely see cows wandering the busy streets, completely unfazed by traffic. Here is a critical law you must know: cows are sacred in Nepal and serve as the national animal. Under Nepali law, harming, injuring, or slaughtering a cow is a severe criminal offense. If you hit a cow with a rental vehicle or harm one, you face a serious prison sentence. Let them have the right of way, always.

When visiting religious sites like the grand Boudhanath Stupa or Swayambhunath, pay attention to the direction people are walking. You must always walk around Buddhist stupas, shrines, and mani stones in a clockwise direction. Walking counter-clockwise is considered highly disrespectful. Also, be mindful of your body language. Never point the soles of your feet or your fingers directly at a religious statue, shrine, or even another person. If you need to point out a temple feature, do so with an open, flat hand facing upwards.

Pro-Tip: Always remove your shoes before entering a Hindu temple or Buddhist monastery. Respect local customs and keep your shoulders and knees covered.

Surviving Transit: Microbuses, Taxis, and Trekking Permits

Getting around Nepal is an adventure in itself, but it can test your patience. If you are tempted to try local microbuses, prepare for an extremely cramped ride. These microbuses are packed to the roof, and your luggage will likely be thrown onto the top rack, secured only by a rope. You pay in cash to the young conductor hanging out the door, who yells destinations in rapid-fire Nepali.

For intercity travel, such as traveling from Kathmandu to Pokhara, I highly recommend booking a tourist bus instead. Companies like Jagadamba or Greenline offer air-conditioned, much safer, and far more comfortable journeys through the winding mountain roads.

If you take a taxi within the cities, you will find that drivers rarely agree to use the meter. Negotiation is key. Decide on a price before you get in, and be prepared to negotiate hard because tourist prices are inflated. Ask your hotel manager beforehand what a fair rate is to your destination.

Planning to trek? Whether you are heading to the Everest Base Camp or the Annapurna Circuit, you must obtain a TIMS (Trekkers’ Information Management Systems) card and specific national park entry permits. Do not try to sneak past checkpoints. More importantly, solo trekking is now illegal in most regions of Nepal for safety reasons. You are required by law to hire a licensed guide. It keeps you safe and supports the local economy.

Quirky Adventures & Unlimited Refills of Dal Bhat

If you want a view of Mount Everest without the grueling two-week trek, book an early morning mountain flight from Kathmandu. These flights take off at sunrise, offering a window seat to view the tallest peak on earth up close. It is absolutely breathtaking. If you prefer the water, whitewater rafting down the Trishuli River is an absolute must-do. The rapids are wild, and the scenery is pure jungle bliss.

All this adventure will work up a massive appetite, and Nepal’s food does not disappoint. You have to try momo—steamed or fried dumplings filled with spiced buffalo meat, chicken, or vegetables, served with a rich sesame tomato dipping sauce. And then there is Dal Bhat, the national dish consisting of rice, lentil soup, and vegetable curry. The best part? In Nepal, Dal Bhat is served with a rule of continuous refills for free. The servers will walk around and scoop more rice and curry onto your plate until you literally beg them to stop.

The Drone Trap: Don’t Get Fined by the CAAN

Bringing a drone? Leave it in your bag unless you have weeks to spare for paperwork. It is strictly illegal to fly drones in Nepal without official permits from the Civil Aviation Authority of Nepal (CAAN) and the Department of Tourism. Police are very strict. If you are caught flying an unauthorized drone, it will be confiscated immediately, and you will face heavy fines.

Staying Connected: Why You Need a Nepal eSIM

One of the biggest headaches in Nepal is getting a local physical SIM card. At the airport, you will face long queues, and you will need to provide a passport photo, a photocopy of your visa, and give your physical fingerprints. Yes, fingerprints just for a SIM card! And if you head into the mountains, finding a shop to reload your credit is nearly impossible.

Skip the hassle entirely. With a Nepal eSIM, you can activate your data plan the moment you arrive. It connects you to local networks like Ncell or Nepal Telecom instantly, ensuring you have reliable maps, translator apps, and access to emergency services even on remote mountain roads.
