Grading of hiking, trekking and mountaineering in the central Himalayan destinations are in inherently subjective. Wikipedia explained correctly that the grading is highly dynamically influenced by technical difficulty, length of route, protection rating, among others.
Eco-friendly Team has roughly classified our adventure eco holiday trips based on the Alpine System. As per the features of subjectiveness, the classification itself may highly subjective, we afraid. Base on this fact, we would like to remain you that below classification is only understand as rough information.
F: facile (easy). Straightforward, possibly a glacial approach, snow and ice will often be at an easy angle. Our most easy adventure eco holidays such as Shivapuri Peak, Tamang Hills, Chepang Hills, Nagarjun Hill Circuit routes are under this group. Please note that this group of our adventure holidays rarely touch snowline and normally not at the ice and no glacial approach at all.
PD: peu difficile (slightly difficult). Routes may be longer at altitude, with snow and ice slopes up to 45 degrees. Glaciers are more complex, scrambling is harder, climbing may require some belaying, descent may involve rappelling. More objective hazards. Base on unique features of Nepal central Himalayan destinations, trekking to Langtang Valley, Ghorepani trekking and similar adventure eco holidays are classified in this level.
AD: assez difficile (fairly difficult). Fairly hard, snow and ice at an angle of 45-65 degrees, rock climbing up to UIAA grade III, but not sustained, belayed climbing in addition to a large amount of exposed but easier terrain. Significant objective hazard. Base Camp adventure eco holidays such as Everest Base Camp, Annapurna Base Camp and similar level of routes are graded in this
D: difficile (difficult). Hard, more serious with rock climbing at IV and V, snow and ice slopes at 50-70 degrees. Routes may be long and sustained or harder but shorter. Serious objective hazards. Himalayan high pass above 5000 meters long and hard routes are categorized as ‘D’.
TD: très difficile (very difficult). Very hard, routes at this grades are serious undertakings with high level of objective danger. Sustained snow and ice at an angle of 65-80 degrees, rock climbing at grade V and VI with possible aid, very long sections of hard climbing. All peak climbing adventure trips to Island, Mera, Pharchamo and Nayakang are classified in this group.
ED1/2/3/4: extrêmement difficile (extremely difficult). Extremely hard, exceptional objective danger, vertical ice slopes and rock climbing up to VI to VIII, with possible aid pitches. All mountaineering expeditions except Mt. Everest is classified in this group.
ABO: Abominablement difficile (abominable) Difficulty and danger at their limit. Mt. Everest mountaineering expedition is graded as ABO.
Often a + (pronounced Sup for supérieur) or a − (pronounced Inf for inférieur) is placed after the grade to indicate if a particular climb is at the lower or upper end of that grade (e.g., a climb slightly harder than “PD+” might be “AD −”).

Very good value for money spent. We all arranged and generally well managed.
