Walking track grades explained: what Grade 3 actually means
By Aus Trails · Reviewed against the current app.
A grade on a trailhead sign is a statement about the track, not about you. Australian parks largely use the Australian Walking Track Grading System (AWTGS), a five-point scale describing surface, steepness, signage and the experience a walk assumes. Aus Trails shows four labels of its own — Easy, Moderate, Hard and Expert — and this guide explains both, and where they stop being a promise.
What the five AWTGS grades describe
The grading system describes the track, not the weather, your fitness or the day you happen to walk it. Grade 1 is a short, flat, hardened surface suitable for people with reduced mobility, including wheelchair users. Grade 2 assumes no bushwalking experience: a clearly marked track, gentle hills, a firm surface underfoot.
Grade 3 is the one people search for, and the honest summary is "some bushwalking experience recommended". The track is still formed and signposted, but it can include short steep sections, steps and uneven ground. Grade 4 assumes real bushwalking experience: tracks can be rough, steep and only intermittently marked. Grade 5 assumes you can navigate without a track at all.
Individual parks apply the scale themselves, so a Grade 3 in one reserve can feel harder than a Grade 3 in another. Treat the number as the park’s considered opinion rather than a measurement.
How that maps to the labels in Aus Trails
Aus Trails shows one of four labels on every trail: Easy, Moderate, Hard or Expert. Across the 481 trails currently in the app that breaks down as 230 Easy, 138 Moderate, 59 Hard and 54 Expert.
Read them as a rough correspondence, not a conversion table. Easy sits broadly where AWTGS Grades 1 and 2 sit. Moderate overlaps Grade 3. Hard and Expert cover the territory of Grades 4 and 5, where unmarked sections and sustained steepness become normal rather than exceptional.
Where a park publishes its own grade on a signpost or a notice, that grade wins. It was assigned by people who walk the track.
Read distance and elevation, not just the grade
A grade compresses several independent facts into one word, and two of those facts are published separately on every trail page: how far the route goes, and how much it climbs. A 2 km walk with 300 m of ascent and a 9 km walk with 100 m of ascent can carry the same label and ask completely different things of you.
The elevation profile is the fastest way to see which one you are looking at. A profile that rises steadily is a different day from one that is flat for an hour and then goes almost vertical, even when the totals match.
- Open the trail and check the grade label first for a general sense.
- Read the mapped distance and the route type — a 5 km return walk is 5 km total, not 5 km each way.
- Look at the shape of the elevation profile, not only the total climb.
- Check the park’s own current notices before you go.
What a grade does not tell you
A grade is assigned in reasonable conditions. It does not know that the creek crossing is running high, that the track was burnt last summer, or that the forecast turned. Rain changes a rock scramble more than it changes a distance.
It also says nothing about you. Party size, the youngest or least experienced walker, daylight remaining and how much water you are carrying all move the real difficulty of a walk. Grade the day, not only the track.
