Trekking is possible anytime of the year depending on where you are going. The popular season are spring and autmn. During winter, it is posssible at lower altitudes. During the monsoon season, you can trek in the rain shadow areas north of the Himalaya like Mustang, Upper Manang and Dolpa. These place are out of reach of rain clouds because of the high mountaind and are uneffected by the mansoon.
In this time the route are less crowded and if you are a keen botanist, you will revel in lush vegetation as meadows blossom in full swing. To ensure quality service and safety, it is advisable to follow our trekking program. We have two type of trekking i.e. Camping and Tea-house program. We will cook food ourselves and sleep in tent in camping program. In Tea-house program, we provide one guide and porter and eat in the restaurant of the way. So you can choose any program from our list.

If you trek in the Annapurna, Makalu or Kanchenjunga regions, you will enter a Conservation Area and must pay a conservation fee of Rs 1000 (Rs 2000 for Annapurna). This must be paid in advance in Kathmandu. A national park fee of Rs 1000 is also collected at the time you enter a national park. 
Physical Conditioning
The better your physical condition, the more you will enjoy the trek. You do not have to undergo a rigorous training programme. Just do as much walking as you can up and down hills, up (and down) stairs in your office. Take weekend hikes in the mountains. Walk to work. Jogging and cycling are useful training for a trek. Whenever possible, make your hikes in the same shoes that you will use for the trek. You must remember that you are going on a hiking trip among the highest mountains on earth. The hills are steep and you may be travelling in hot weather, in snow or in rain. You will often be tired, and you must be prepared for this. However, anyone in good health can complete a trek if you hike slowly, and spend a little effort now to get into good physical condition.
Clothing & Equipment
Your trek outfitter will normally provide two person waterproof tents, foam mattresses, and all cooking and eating utensils. You will need your own warm clothing, walking shoes, sleeping bag and personal equipment. During the day you will carry your camera, jacket, and water bottle in a rucksack. The rest of your equipment, including your sleeping bag, will be carried by porters. 
All hiking will be on trails. You will not need any climbing equipment such as ropes, ice axe, or crampons at any time during the trek. The equipment check list that follows details the equipment you will need for your trek. Most of these items are available for rent or sale in Kathmandu, but all trekking equipment in Nepal is either used equipment that was sold by other trekkers or mountaineering expeditions or locally made reproductions of internationally known brands. The local rucksacks, duffel bags and rain ponchos are inexpensive and will usually stand up to the rigors of a trek or two. Don't be fooled into thinking that you are getting a brand name item, however; most new looking rucksacks available in the bazaar are made in Nepal from imported Korean nylon. 
In Kathmandu casual clothes are the rule, unless you get invited to a formal Nepal government or embassy reception. 
Equipment Check List
• Jeans or slacks 
• Towel and toilet kit 
• Underwear 
• Gloves or mittens 
• Sleeping bag, warm to 20 degrees F, either down or fibrefill (or you can rent one in Kathmandu) 
• Parka, down or fibrefill; a ski jacket is ok 
• Sweater, wool shirt or acrylic pile jacket. 
• Duffel bag, canvas or nylon, without a frame (for porters to carry) 
• Daypack or rucksack, waterproof, for you to carry 
• Water bottle 1 litre or 1 quart; be sure that it does not leak. 
• Flashlight or headlamp 
• Walking shoes: either boots, light hiking or running shoes, well broken in. As there may be rain, mud or snow; boots are sometimes necessary therefore you should bring them despite the extra hassle. Many times the entire trek can be done in tennis shoes, but if there is snow, you run the risk of frostbite, or at least cold feet if you do not have boots. If your feet are small (size 10 or less), you can rent boots in Kathmandu. 
• Hats, one with a brim for sun; one wool for cold weather. 
• Sunglasses or goggles - very important for travel above 12,000 feet. Absolutely essential for Everest treks, optional for Annapurna treks (though they may be necessary in December and January when there is snow). 
• Shorts - it may be warm during the day, especially near Pokhara. You will probably not wear shorts on Everest treks. Women should wear skirts instead of shorts. 
• Socks - two or three pairs thick wool or artificial fibre. 
• Shirts - three are recommended: two T shirts and one long sleeve shirt. 
• Pocket knife (Be sure this is packed in your checked baggage to avoid hassles with airport security). 
• Rainwear - a poncho; or you can buy an Indian umbrella in Kathmandu for about $2. 
• Slippers or sandals for campsite wear. Rubber "shower shoes" are available in Kathmandu for about $1 
This list is suitable for most 8 to 10 day treks. Although you can wash clothes during the trek, you may need extra socks and shirts etc. for longer treks. If your trek goes above 3500 metres (about 12,000 feet) for more than one day you should pay particular attention to warm clothing. If you are trekking to higher elevations or during the cold season you should carry both a pile jacket and a down or fibrefill parka. 
An altimeter is an interesting addition to your gear. The weight limit on treks and domestic flights is 15 kg (33 pounds); please make an effort to keep your baggage within this weight limit.
Medical Considerations
On most treks, you will always be within a few days of medical help. If you are on a group trek, the leader should have the medical knowledge necessary to deal with emergencies and evacuation. If you are on your own, you will have to shoulder most of the responsibility for medical problems yourself. The sherpas who will accompany you are not doctors, nor are they first aid practitioners. It is essential that you bring your own first aid kit and be prepared to take care of your own blisters, cuts and scrapes. In the event of a real emergency, the sherpa sirdar will do his best to get you transported quickly to a qualified physician or an airstrip from which you may be evacuated to Kathmandu. 
Medical Supplies
The supplies listed here are recommended for any trek. Since some of them are prescription drugs, you should visit your doctor and discuss the trip with them and obtain prescriptions. If your doctor makes recommendations contrary to the suggestions here, follow your doctor's advice, and obtain substitutes for these items. It is not necessary to burden yourself with a lot of medicines for the trek, though you should carry enough to take care of minor problems. The ones listed here are sufficient for most situations. You should be sure to provide your supply of own aspirin, band aids, etc. If you are taking an extended trek, you should consult Dr David Shlim's medical chapter in Stan Armington's Trekking in the Nepal Himalaya and equip your party to deal with possible problems and emergencies.
Your own physician and your local Public Health Service are the best sources of information about immunisations necessary for Nepal. The list of recommended injections here includes immunisations usually recommended for trekkers in Nepal. Hepatitus and Meningitis protection is also strongly recommended. It is a good practice to have your jabs recorded in a yellow international health certificate. 
Recommended Injections
Polio (oral) 
Malaria (only if you will be visiting a jungle lodge) 
Meningitis Meningococcal A/C vaccin
Acclimatization is important for the trekking above 3500m. Our trekking schedules have been carefully designed to maximize your ability to acclimatize safely. We ascend slowly and ensure an adequate number of rest days. However, it is still possible for mountain sickness and your tour leader or Sirdar will be watching for symptoms with an experienced eye throughout the trip. These symptoms are commonly headache, nausea, lethargy and sometime breathlessness. If you or any of the group members display any of these symptoms he will be able to provide informed advice and ensure a proper course of action. Your tour leader will advise you more thoroughly regarding the altitude and most of the problems prior to starting on trail.
