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 mythical Himalayan range and its Mount Everest. While there is a hiking route to suit every level, kit and equipment should not be taken 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 plains 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 trek in Nepal depends on the area, altitude and type of route. However, two seasons are recommended: autumn and spring.
Autumn runs from October to November. At this time, the sky is clear after the monsoon, visibility over 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, 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 treks at mid-altitude are accessible, the cold is intense and certain passes are closed. The monsoon season, between June and September, is not recommended either. Summits 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 technique is recommended. It involves adding or removing layers according to the temperatures you encounter.
The base layer is breathable. Opt for technical t-shirts or thermal underwear. The mid-layer is insulating. Choose fleeces or hiking down jackets, which pack down easily. Finally, the outer layer is protective. Bring waterproof jackets and windproof shells or ponchos to face rain, wind or snow.
As with the upper body, the lower half of your Nepal trek outfit consists of several layers. Put on thermal leggings, then warm hiking trousers, and finally over-trousers for summit ascents.
Hiking boots must be chosen with care. For high-altitude trekking, we recommend ankle-support boots for good ankle stability. 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 the bivvy.
Protecting your extremities is essential on a trek. Depending on the 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, fleece or silk liner gloves or warm wool gloves are recommended. Finally, opt for technical socks in merino wool or a blended fabric.
What accessories should you pack?
Some accessories are very useful to complete your outfit for a trek in Nepal. First, bring trekking poles to take the strain off your joints and maintain good stability. Also 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-protection sunscreen and a lip balm with SPF are therefore essential. Do not forget to bring category 3 or 4 sunglasses to protect your eyes from glare off snow or glaciers.
In case of an early start or a power cut, remember to bring a head torch with spare batteries. To drink safely, carry purification tablets, a water filter or a filtering water bottle. At night, temperatures drop significantly. Pack a sleeping bag with a comfort rating of at least -10°C.
A first-aid kit is essential. Fill it with plasters, antiseptic, gauze pads, painkillers and your personal medications. Finally, a waterproof pouch is very handy for protecting all your documents during the ascent.
Additional tips for a successful trek
Most treks 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 and loss of appetite. These symptoms can then progress to pulmonary or cerebral oedema, which can be life-threatening.
To avoid any complications, you must acclimatise properly. To do so, gain altitude gradually, at 300 to 500 metres of elevation per day. Avoid overexertion 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 suitable equipment and do not 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 remember to give them a decent tip at the end. As a rule, this amounts to 10–15% of the trek price.
Finally, check on 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 will get the most out of every moment of your trek in Nepal.
