How to Prepare for Trekking in Nepal

How to Train for Nepal’s Trails: Acclimatizing and Training

Wilderness Travel has more than 40 years of experience operating safe and successful treks throughout the high mountain wonderland of Nepal. Hiking in Nepal is truly a “bucket list” experience for many travelers, but it comes with inherent risks and requires adequate pre-trip training and preparation.

Start Training Before the Trek

Improving your cardiovascular endurance should be a key part of preparation for a Nepal trek, especially at high altitudes. Running, cycling, and swimming are great ways to improve your cardio. We suggest starting your fitness program at least two months before your trek begins. Try to do your cardio exercise three times a week (or more if you are comfortable with it). Using a StairMaster-type machine is excellent practice for hiking, as is climbing staircases and going on hill hikes for several hours (also a great way to break in your boots).

In addition to your training program, learn how and when to replenish yourself with electrolytes when you’re hiking, which can help your endurance and your overall enjoyment of a high-altitude trek.

Break in Your Gear

Becoming familiar with your gear is crucial. Make sure to break in your boots, wearing them on your local hikes or while at the gym. Well-broken-in boots prevent blisters that can really reduce your enjoyment on a trek. We strongly recommend the use of hiking poles. Practice hiking with them at home before you bring them on the trek.

Diamox & Altitude Preparation

It is not uncommon to experience headache, nausea, loss of appetite, sleeplessness, shortness of breath, and fatigue at altitude. These can occur when you first arrive at higher elevations and usually decrease in severity with time. We advise you to consult with your physician at home about getting Diamox prescribed to you for your Himalayan trek. Especially if you have never been to elevations as high as you will be going on your trip, or if you have struggled with altitude sickness before. If you’ve been to the same elevations you will be hiking on this trip and didn’t experience altitude sickness, Diamox may not be necessary, but talking with your doctor is never a bad idea. You can learn more about altitude and how to prepare for it in our video linked below.

Elevation Exposure

If you’re able to spend a few days before your trek at elevation, that can be very helpful to get your body to slowly acclimatize. If you can’t do this at home, many people like to arrive in Kathmandu a few days early to acclimatize (at 4,446 feet) and explore this fascinating city on their own.

Rest and Hydrate

When you get to Nepal and as you start your trek, be sure to do everything you can to be sure you’re staying hydrated and get enough sleep. This begins on your flight, many people can become dehydrated simply by breathing the low-humidity air on a long flight and not drinking enough water to compensate. Do everything you can to ensure you arrive well rested and are not already sleep deprived when the trek starts–arriving a day or two early to catch up on sleep and adjust to the new time zone may be helpful if you’re concerned. Lack of sleep and dehydration are the primary causes of altitude sickness that are within your own control, so do everything you can to set yourself up for success!

What Trail Conditions to Expect in Nepal

The hikes in Nepal can see many different terrains depending on your elevation. At lower levels, paths are typically paved concrete, but may be dusty from pack animals who share the trail. As you pass through lush pine and rhododendron forests, altering between flat to steeper climbs, you will notice the path becoming uneven. Eventually, the rest of your climb will become rugged, rough and rocky, with larger boulders. This will require navigating through some uneven and unsteady terrain. Nepal is a very popular trekking destination, so even at higher elevations, there is always a clear trail to follow—bushwhacking is not required. As you hit elevations above 10,000 feet, you may encounter icy, windy conditions and much colder temperatures, dropping rapidly after sunset.

Pace Yourself for Maximum Acclimatization

We carefully plan all of our treks to allow for maximum altitude acclimatization as we make a gradual rise to higher altitudes rather than a rushed one. A few rest days are built in to each trek, allowing you to enjoy optional day hikes that help you slowly acclimatize. In addition, we encourage our travelers to hike at their own pace. There will always be a lead guide in the front and a “sweeper” guide at the back who stays with the slowest hiker.
