Outdoor activities are potentially hazardous and carry a significant risk. They should only be undertaken with a full understanding of all inherent risks. These grades are guidelines that must always be used in conjunction with your own experience, intuition and careful judgment.
| Grade | Path, terrain | Requirements |
| T1 Hiking | Good track / path. Flat or slightly inclined terrain, no risk of falling. | Comfortable walking shoes. |
| T2 Mountain Hiking
| Path with continuous track bed. Sometimes steep terrain, slight risk of rockfall / feet slipping. | Competent, agile. Quality hiking shoes. |
| T3 Difficult Mountain Hiking | Paths not always visible, some exposed. Partially exposed sections with risk of slipping/ gravel / unexpected changes in path and terrain. | Previous experience and competent agility needed. High quality hiking boots are essential. Basic to medium alpine experience needed. |
| T4 Alpine Hiking | Paths not always available. Terrain quite exposed, tricky grassy slopes, abrupt changes to paths. | Confidence in exposed terrain, good, robust trekking shoes. Previous alpine experience. Due to weather changes can be difficult to retreat. |
| T5 Difficult Alpine Hiking | Varies between no tracks to grassy/easy climbs. Exposed, challenging terrain, steep paths/ changing terrain/ glacier and snow fields routes with risks of slipping/falling. | Mountaineering Boots Good alpine experience needed with some previous experience of pick and rope. |
| T6 Very Difficult Alpine Hiking | Mostly pathless. Often very exposed, very steep terrain, with increased risk of slipping. | Advanced alpine experience needed, confidence using alpine technical tools. |
