This is one of the first decisions you will face when planning a trek in Nepal, and the answer depends on both the regulations for your chosen route and practical safety considerations.
Nepal's government designates several trekking regions as restricted areas. To enter these zones, you must hold a Restricted Area Permit, and the permit will be issued to solo trekkers. You are legally required to trek with a government-licensed guide.
Restricted areas that require a mandatory guide include:
- Upper Mustang
- Upper Dolpo and Lower Dolpo
- Manaslu Circuit
- Tsum Valley
- Kangchenjunga
- Nar Phu Valley
- Humla
- Limi Valley
However, trekking without support on routes that go above 3,000 to 4,000 metres carries real risks that many first-time trekkers underestimate. If you’re trekking for several days, it’s best to have a licensed, experienced guide with you for safety, navigation, and support along the trail.
What a guide actually does for you
A licensed guide does far more than point you in the right direction on the trail. A good guide will:
- Navigate the route, particularly in poor visibility or when trails split at unmarked junctions
- Explain the Himalayas, culture, and tradition
- Take responsibility when something goes wrong
- Handle permit checks at checkpoints so there are no delays
- Communicate with teahouse owners to secure accommodation in busy seasons
- Monitor your health for early signs of altitude sickness and make decisions about rest or descent
- Coordinate emergency evacuation if needed, including helicopter rescue logistics
- Translate local languages and help you connect with the communities you pass through
Guides vs. porters
A guide leads and manages the trek; a porter carries your main bag (typically up to 25 kg) so you only need a light daypack. Many trekkers hire both. If budget is a concern, a guide-porter, someone qualified to do both roles, is a practical middle option for shorter or lower-altitude routes. On longer, higher-altitude treks, having a dedicated guide and a separate porter gives you better support if anything goes wrong.
All our packages include a licensed, English-speaking guide. Porter support is included on selected packages and can be added to any itinerary.
Nepal has treks for almost every fitness level, from gentle valley walks to serious high-altitude expeditions. The key is matching your route to your current fitness, not your aspirational fitness. Many people worry they are not fit enough; in practice, far more trekkers struggle because of altitude than because of leg strength.
Easy to moderate: Ghorepani Poon Hill
This is a popular choice for first-timers. You walk roughly 5 to 6 hours per day on well-marked trails, with the highest point at Poon Hill (3,210 m). The elevation gain is modest enough that altitude sickness is uncommon. Good general fitness is sufficient; you do not need to train for months beforehand. If you can walk uphill comfortably for 2 hours without stopping, you can do Poon Hill.
Moderate: Langtang Valley
Langtang reaches around 4,984 m at Tserko Ri and involves 5 to 7 hours of walking per day with steady elevation gain. A reasonable base fitness level and at least two weeks of regular hiking or cardio preparation is advisable. Acclimatization days are built into the itinerary.
Challenging: Everest Base Camp and Annapurna Circuit
Everest Base Camp (5,364 m) and the Annapurna Circuit (Thorong La Pass at 5,416 m) are the two routes most people ask about. Both involve:
- 5 to 8 hours of walking per day over 12 to 18 days
- Significant daily elevation gain, often 600 to 1,000 m
- Mandatory acclimatization rest days built into every responsible itinerary
- Cold nights above 4,000 m, which adds physical stress even on rest days
You should be comfortable with sustained uphill walking for 5 or more hours before attempting either route. A 6 to 8-week preparation plan that includes long hill walks, stair climbing, and cardiovascular work will make a real difference to your experience. That said, beginners with good general health do complete both treks every season, provided they follow the itinerary's acclimatization schedule and do not rush. Check our blog on how to train fro everest base camp trek if you aren't aware of it.
The altitude factor
Above 3,000 m, your cardiovascular fitness matters less than your acclimatization. Some very fit people acclimatize poorly; some moderately fit people do well. Following the "climb high, sleep low" principle and not exceeding 500 m of altitude gain per day above 3,000 m is more important than your fitness level when it comes to staying safe.
Nepal has four distinct trekking seasons, and each one suits different routes and travel styles. The short answer that everyone gives is "spring or autumn," but the reality is more nuanced than that.
Spring: March to May
Spring is peak trekking season alongside autumn. Temperatures are comfortable at lower elevations, rhododendrons bloom on the trails below 3,500 m, and mountain views are generally clear in the mornings. Afternoons can bring cloud build-up and occasional light rain, but this rarely disrupts trekking plans.
The downside: spring is the busiest season on the popular routes. Teahouses on the Everest Base Camp trail fill up quickly in April and May, and flights to Lukla or Pokhara can be delayed or cancelled due to high air traffic and weather. Book accommodation and flights well in advance.
Best for: Everest Base Camp, Annapurna Base Camp, Langtang, Ghorepani Poon Hill, Manaslu Circuit.
Monsoon: June to August
Most trekkers avoid the monsoon months, and for good reason on the southern slopes of the Himalayas. Heavy rain makes trails slippery and views are often obscured. Leeches appear on lower-elevation trails. Flight cancellations are frequent at mountain airports.
However, the monsoon does not affect the rain-shadow areas to the north of the main Himalayan range. Upper Mustang, Dolpo, and the Nar Phu Valley sit in a geographical rain shadow and receive very little monsoon rainfall. These routes are ideal in June to August and are far less crowded than during peak season.
Best for: Upper Mustang, Dolpo, Nar Phu
Autumn: September to November
October and November offer the clearest mountain views of the year. The monsoon has washed the air clean by September, and skies are consistently blue. Temperatures are cooler than spring, and the trails are dry. October is the most popular month of the year for trekking in Nepal, which means teahouses and flights are in high demand.
November is a strong alternative: slightly fewer trekkers than October, crisp clear days, and colder nights at altitude. By late November, high passes like Thorong La on the Annapurna Circuit can see snow, so timing matters.
Best for: all major routes, Everest Base Camp, Annapurna Circuit, Langtang, Ghorepani Poon Hill, Manaslu, and Three Passes.
Winter: December to February
Winter trekking is possible on many routes but demands preparation for cold conditions. Temperatures above 4,000 m drop well below freezing at night. Some high-elevation teahouses close for the season, particularly on the Annapurna Circuit above Manang. Trails can be icy and high passes may be blocked by snow.
The rewards are real: very few other trekkers, quieter teahouses, and on clear days, mountain views that are just as sharp as autumn. Lower-altitude winter treks such as Ghorepani Poon Hill or the Annapurna Sanctuary can be excellent in December and January with the right gear.
Best for: Ghorepani Poon Hill, lower Everest region (Namche Bazaar area), Kathmandu Valley rim hikes.

Tips: a note on local custom
Tipping guides and porters is expected and forms a meaningful part of their income. Tipping at the end of the trek is entirely at your discretion based on the service provided.
The permits you need depend on your trekking region and route. For most popular treks, such as Everest Base Camp and Annapurna, the required permits and conservation fees are arranged by your trekking agency and are included in the package price. Restricted-area treks may require additional permits and specific documentation.
Before your trek, you will generally need:
- Passport: A valid passport is required for permit applications and trekking registration.
- Passport-size photos: Some permits or registrations may require recent photos.
- Trekking permits: Depending on the route, you may need a TIMS card or a specific trekking permit.
- Conservation or national park fees: Treks passing through protected areas require the relevant entry permits or conservation fees.
- Restricted-area permits: Routes such as Upper Mustang, Manaslu, Nar Phu Valley, and other restricted regions require special permits with additional conditions.
- Travel insurance: Your policy should cover trekking at the altitude of your chosen route and, where required, emergency helicopter evacuation.
Who arranges the permits?
If you book a guided trek with Sublime Trails, our team handles the required trekking permits, conservation or national park fees, and local paperwork before and during your trek. The applicable permit costs are included in your package unless specifically stated otherwise.
Important: Permit requirements and fees can vary by trekking region, so check the inclusions for your specific trek before departure.
Trekking in Nepal is generally safe when you follow a well-planned itinerary, acclimatize properly, and trek with an experienced guide. On high-altitude routes, your guide monitors your condition, helps you maintain a safe pace, and can arrange medical assistance or emergency evacuation if necessary.
Altitude sickness is a genuine risk, particularly above 3,000 m, which is why our itineraries include appropriate acclimatization days. If you develop symptoms, your guide will assess your condition and may recommend rest or descent rather than continuing higher.
Mountain weather can also cause flight delays, route changes, or itinerary adjustments. When conditions change, our guides and operations team prioritize your safety and work with you to find the safest practical solution.
Travel insurance covering high-altitude trekking and emergency helicopter evacuation is required.
Packing well can make a big difference to your comfort and safety on the trail. Carry too much, and the extra weight can quickly become tiring. Leave out an important item, and replacing it in a remote mountain village may not be easy.
Your packing list should depend on the trek, season, altitude, and expected weather conditions. The following is a practical starting point for most multi-day treks in Nepal, with additional warm or technical gear needed for higher and colder routes.
Footwear and Clothing
- Trekking boots: Choose comfortable, waterproof boots with good grip and ankle support. Break them in well before your trek rather than wearing a brand-new pair on the trail.
- Camp shoes or sandals: Lightweight footwear gives your feet a break after a long day of walking.
- Moisture-wicking base layers: Pack 2 to 3 sets of synthetic or merino wool layers. Avoid cotton because it absorbs moisture and takes longer to dry.
- Fleece or warm mid-layer: Useful for cooler mornings, evenings, and higher elevations.
- Insulated or down jacket: Essential for high-altitude treks and cold evenings. The level of insulation you need depends on the season and maximum altitude.
- Waterproof jacket and trousers: Useful for rain, snow, and changing mountain weather.
- Trekking trousers: Two pairs of comfortable, quick-drying trousers are generally practical.
- Warm hat and sun hat: Bring both for protection from cold temperatures and strong mountain sunlight.
- Gloves: Lightweight gloves are useful for regular trekking, while insulated gloves are important for colder, higher-altitude routes.
- Trekking socks: Bring around 4 to 5 pairs of wool or synthetic trekking socks.
Trekking Gear and Accessories
- Sleeping bag: Choose one with a temperature rating suitable for your trek and season. Colder and higher routes require a warmer sleeping bag.
- Daypack: A 20 to 30-litre backpack is generally enough for carrying water, snacks, extra layers, sunscreen, and other daily essentials.
- Duffel bag: A 60 to 80-litre duffel is practical for carrying your main trekking gear. Avoid hard-shell suitcases on multi-day mountain routes.
- Trekking poles: Helpful on steep ascents and descents, particularly on longer or high-altitude treks.
- Headlamp: Bring a headlamp with spare batteries or a reliable rechargeable battery.
- Water bottle or hydration bladder: Choose one with enough capacity for your daily water needs. You may need more water on longer or warmer walking days.
- Water purification: Carry purification tablets, drops, or a suitable water filter if you plan to treat drinking water yourself.
- Sunglasses: Choose good-quality sunglasses with strong UV protection. Glare becomes particularly intense at higher elevations and around snow.
- Sunscreen: SPF 50 or higher is recommended because UV exposure increases with altitude.
- Lip balm with SPF: Helps protect your lips from strong sunlight, cold, and dry mountain air.
Personal Medication and First Aid
Carry a small personal medical kit and any medication you normally need.
- Prescription medication: Bring enough for the entire trip, plus some extra in case of unexpected delays.
- Altitude medication: If you are considering acetazolamide (Diamox) for altitude sickness prevention, discuss whether it is appropriate for you with a qualified healthcare professional before travelling.
- Pain relief: Paracetamol or ibuprofen can be useful for headaches and general aches if they are safe for you to take.
- Oral rehydration sachets: Useful for replacing fluids and electrolytes when needed.
- Blister treatment: Bring blister plasters or similar products and treat hot spots early.
- Basic wound care: Include antiseptic, adhesive plasters, and small dressings.
- Diarrhoea medication: An appropriate over-the-counter option, such as loperamide, can be useful in an emergency if it is suitable for you.
What Can You Rent or Buy in Kathmandu and Pokhara?
If you do not want to purchase every piece of trekking equipment, Thamel in Kathmandu and Lakeside in Pokhara have numerous shops selling and renting trekking gear.
Cancellation requests must be submitted in writing to Sublime Trails. The applicable cancellation charge depends on how far in advance you cancel your trip and whether it is a Nepal trip or an overseas trip.
