Easy trips are usually suitable for travellers with no previous multi-day walking experience. The easy trek/tour involves no difficult climb or ascent to high altitudes but includes some drive and is suitable for most people for about a week. However, being at a lower altitude, less than 3,500 meters, does not mean that the trip is of any less interest. The easy treks and tours are considered to have a good access of teahouses, guesthouses or lodges and deluxe hotels or resorts.
Travellers looking for something a bit more energetic and challenging than easy trips can choose medium level trips. The medium level trek/tour involves part of drive, ascents and descents as you climb to higher altitudes (below 4,500 meters) where you are rewarded with close-up views of bigger mountains. The medium level trips have a good access of teahouses, guesthouses or lodges and suitable for about a week to 10 days.
Travellers with some previous mountain walking experience can go for medium-hard trips. The medium-hard trip generally involves ascending up to altitudes of between 4,500 meters to 5,500 meters. This includes some steep climbing and ropes are not necessary though. Driving tours above such altitude include while travelling in Tibet.
Travellers seeking for real adventures should try such trips. Hard trek involves some steep ascents to high altitudes more than 5,000 meters with a possibility of rope assisted climbing. Trekkers will also need strong stamina to complete one of these wild treks that may last for 21-28 days. Hard treks demand fully supported camping crew. Trips in Tibet include driving also in most part of such tours.
Travellers seeking for technical climbing and expeditions to the peaks above 6,000 meters should join on such trips. One must have hard physical effort at extreme altitudes which will require thorough preparation. All treks associated with a climb are based on camps with full excess of climbing gears. It may cause long term fatigue after the trip.
