Travellers with no previous experience are usually offered easy trips. 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 3500 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 an easy trip are offered medium level trips. The medium level trek/tour involves part of drive, ascents and descents as you climb to higher altitudes (below 4500 meters) where you are rewarded with close-up views of bigger mountains. The medium level trips are considered to 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 are offered medium-hard trips. The medium-hard trip involves ascending up to altitudes of between 4500 meters to 5500 meters with some steep climbing, ropes are not necessary though. Driving tours above such altitude include while travelling in Tibet.
Travellers seeking for real adventures are offered such trips. The hard trek involves some steep ascents to high altitudes more than 5000 meters with the possibility of rope assisted climbing and need stamina to complete one of these wild treks that may last for 21-28 days. Hard treks demand fully supported camping crew. Part of drive is also included in such tours and treks undertaken in Tibet.
Travellers seeking for technical climbing and expeditions to the peaks above 6000 meters are offered 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.
