How Long Does a Bushwalk Take? How to Estimate Walking Time Before You Go

A 10km walk might sound like a couple of hours, until it climbs 600 metres...the track turns to rock...and you're still an hour from the car as the sun drops. The lesson? Distance alone can tell you very little.

So, here's how to estimate how long a walk will actually take you, before you leave the carpark.

Booking ahead means you know your site is waiting. Most parks let you reserve

Distance vs Elevation vs Terrain: Which One Actually Slows You Down

Distance

Distance sets the baseline, but it's the least of the three.

Most people can hold a steady pace on flat, formed track for hours.

Elevation

Elevation is the big one. Climbing slows everyone down, and descending isn't free either.

Steep downhills are slow, hard on the knees, and tiring late in the day.

Terrain

Terrain is the multiplier people often forget. Your pace on a smooth fire trail can be double your pace on rough, rocky or root-covered track. Off-track travel is slower again.

The same 10 km can be a 2-hour stroll or a 6-hour day depending on the second two.

Estimating Walking Time: A Simple Rule of Thumb

Australian bushwalking clubs use a version of a long-standing walkers' formula (Naismith's Rule), adapted for Australian conditions.

For an average walker, allow roughly one hour for:

Every 2 km on rough track

Every 1 km travelling off-track

Every 4 km on easy, well-formed track

Then add time for climbing - hills are what blow estimates out. A common allowance is around 10 minutes for every 100 m of ascent on top of the distance time.

Add rest and meal stops on top - they're not included in the formula

Expect to be slower at the end of the day than the start.

In a group, estimate from the slowest walker - the group moves at their pace.

Worked example: a 10 km walk on formed track (2.5 hrs) with 400 m of climbing (about 40 min) plus lunch and breaks (30 min) is a 3.5 to 4 hour day, not the 2 hours the distance suggests.

How to Read a Trail Description Properly

1. Look for four things: distance, total ascent (sometimes "elevation gain"), track surface, and the AWTGS grade. [See more - Blog: Australian Walking Track Grades Explained.]

2. "Return" vs "one way" catches people constantly. Check whether the distance is the whole trip or half of it.

3. If a description gives a time but no ascent figure, be suspicious. Is it hiding the number that matters most?

4. Loop walks rarely split the climbing evenly. Check whether the big climb comes first or last.

Bushwalking's Weather Exposure, Facilities and Escape Points

A day walk kit is small. It should include:

• Exposure changes your time budget: a shadeless ridge in summer heat means more stops, more water and a slower pace.

• Check where water, toilets and shelter sit along the route - on many tracks the answer is "nowhere".

• Know your escape points: road crossings, junctions or shortcuts where a walk can be cut short if time, weather or energy runs out.

• Work backwards from sunset. Decide your latest turnaround time before you start, not when you're tired.

Why Signposted Times Are Often Wrong?! (and Who They're Written For)

Signposted and brochure times are broad estimates written for a wide range of visitors. They don't know you, your knees, your children or your habit of stopping to take photos....

Some are signposts feel overly generous, some are ambitious, and they're not always consistent across Australia.

So, use them as a cross-check, not a plan. Do your own estimate - of distance, climb, terrain, and breaks - and you'll be well placed to plan in alignment with the sign and the sun every time.

After each walk, compare your actual time to your estimate. Keep notes of your walks for next time. Two or three walks in, you'll know your own numbers. Soon, you'll probably be recommending the best walks most suitable to friends and family.
