Nepal attracts hundreds of thousands of visitors every year. This small country, sitting at the crossroads of the salt and silk routes, is traversed by the legendary Himalayan range and its Mount Everest. While everyone can find a hike suited to their level, gear is not something to take lightly. Cimalp reveals what to wear for a trek in Nepal.
What is the best season for a trek in Nepal?
Nepal is divided into three main zones: the Terai lowlands with a subtropical climate, the hills with a temperate climate, and the mountains with a cold, dry climate — ideal for high-altitude hiking.
The best time to go trekking in Nepal depends on the zone, altitude and type of route. However, two seasons are recommended: autumn and spring.
Autumn runs from October to November. At this time of year, the skies are clear after the monsoon, visibility across the Himalayan peaks is exceptional, and temperatures are pleasant. Routes such as the Annapurna Circuit or Everest Base Camp are, however, extremely busy.
Spring runs from March to April. The weather is dry and mild, the rhododendrons are in bloom, visibility is slightly less sharp than in autumn, but conditions remain generally very good and crowds are smaller.
Unlike autumn and spring, other periods are best avoided. Winter, between December and February, is harsh. While a few mid-altitude treks remain accessible, the cold is intense and some passes are closed. The monsoon season, between June and September, is not recommended either. Peaks are cloud-covered, rainfall is heavy, trails are slippery and leeches are rife.
What is the right outfit for a trek in Nepal?
The ideal outfit for a trek in Nepal depends on weather conditions and altitude. To dress in the best possible way, the layering system is recommended. It involves removing or adding layers according to the temperatures you encounter.
The base layer is breathable. Go for technical t-shirts or thermal underwear. The mid layer is insulating. Choose fleeces or hiking down jackets, easily compressible. Finally, the outer layer is protective. Pack waterproof jackets and windbreakers or ponchos to deal with rain, wind or snow.
Just like the upper body, the lower half of your Nepal trek outfit is made up of several layers. Put on thermal leggings, then warm hiking trousers, and finally over-trousers for summit ascents.
Hiking shoes must be chosen carefully. For high-altitude terrain, we recommend high-cut boots for good ankle support. Also prioritise grippy soles, a waterproof membrane and a durable, well broken-in pair. You can also bring a lighter pair for lower-altitude stages and sandals for camp.
Protecting your extremities is essential on a trek. Depending on altitude, pack a warm beanie and a buff against the cold, and a cap or UV-protective hat against the heat. For good hand protection, liner gloves in fleece or silk, or warm wool gloves are recommended. Finally, go for technical socks in merino wool or a blended fabric.
What accessories should you bring?
Some accessories are very useful to complete your Nepal trek outfit. First, equip yourself with trekking poles to take the strain off your joints and maintain good stability. Then pack gaiters. They help keep your feet warm and dry in wet or snowy conditions and are ideal for summit ascents.
At altitude, the sun is intense, even on overcast days. A high-SPF sunscreen and an SPF lip balm are therefore essential. Don't forget to bring category 3 or 4 sunglasses to protect yourself from glare off snow and glaciers.
For early starts or power cuts, remember to pack a head torch with spare batteries. To drink safely, bring purification tablets, a water filter or a filtering bottle. Nights are cold, so pack a sleeping bag with a comfort rating of at least -10°C.
A first aid kit is a must. Fill it with plasters, antiseptic, gauze pads, painkillers and your personal medication. Finally, a waterproof pouch is very handy for keeping all your documents safe during the ascent.
Additional tips for a successful trek
Most hikes in Nepal take place at high altitude. Above 3,500 metres, you risk being exposed to Acute Mountain Sickness (AMS). It manifests as headaches, severe fatigue, sleep disturbances, nausea, loss of appetite… These symptoms can then progress to pulmonary or cerebral oedema, which can be fatal.
To avoid any complications, you need to acclimatise properly. To do so, gain altitude gradually, at 300 to 500 metres of elevation per day. Don't overexert yourself and stay well hydrated. If symptoms persist, descend calmly.
In certain areas of Nepal, guides and porters are compulsory. Their wellbeing must not be overlooked. Check that they have appropriate equipment and don't hesitate to share mountain gear with them. Make sure porters are not carrying more than 15 kg, learn a few words of Nepali before the ascent, and don't forget to tip them decently at the end. As a rule, this amounts to 10–15% of the trek price.
Finally, find out about permits and local regulations. Depending on the region, several documents may indeed be required. By planning your itinerary carefully and choosing the right gear, you'll make the most of every moment of your trek in Nepal.
