I miss the Rockies. Living in Canada for over three years gave me access to some of the most impressive mountains in the world — and while I’m stoked to call Perth home again, I do miss the vertical ascents, the scrambles, the satisfaction from planting feet on a massive peak. That’s why I started hunting for Perth’s toughest hiking trails.
Perth’s surrounds might not have the snow-capped peaks of alpine ranges, but that’s part of its subtle intrigue: you can build some very challenging hikes within a couple of hours of the city by combining distance, terrain and sustained climbing.
Proudly, this isn’t a generic “best hikes” list. It’s a practical classification for hikers who care about how far a track actually is, how steep it gets, and whether it feels hard in real terrain — not just on paper.
(That said, a note up front: there isn’t a central database of gradient info for WA trails the way AllTrails publishes distance and elevation gain. Where gradient estimates aren’t directly available from trail providers, I’ve leaned on official walk grading, elevation gain and terrain descriptions to infer how tough it feels on the ground — and have said so clearly.)
If you’re new to judging hike difficulty beyond “how long is it?”, my companion article How hard is this hike really? goes deeper into why metrics like gradient and elevation gain matter just as much as length for your experience on the trail.

How We’ve Classified Hikes
To compare apples with apples, each hike below is summarised with:
- Distance – total kilometres (approximate)
- Elevation gain – total climbing metres where available
- Claimed difficulty – using official grade standards (Grade 3 moderate, Grade 4 hard etc) plus gradient notes when known
- Why it feels tough – terrain, surface and features that make you earn it
Tough Day Hikes From Shorter to Longer
Echidna Trail to Walyunga National Park
Distance ~11 km, Elevation gain ~432 m, Grade 4 (Hard)
Echidna Trail is a full loop that packs steep climbs and rocky footing into a relatively compact distance. The early sections follow the river but soon turn uphill through woodland to panoramic views over the Avon Valley, with rough surfaces and loose gravel sections that demand careful footwork. Grade 4 means experienced walkers are recommended.
Feels tough because: steep ascents early and mid-trail, rough and rocky track underfoot, sustained climbing.
Numbat Trail to Paruna Wildlife Sanctuary
Distance ~12 km loop
Elevation gain officially listed around ~560–620 m
Moderate to Hard (Grade 3/4)
The Numbat Trail is widely regarded locally as one of the toughest single-day hikes near Perth. The trail features lots of stairs, frequent ups and downs through wandoo woodland and creek valleys, and a surprising amount of vertical gain over its length. Multiple sources list lengths around 12–13 km and classify it as moderate to challenging.
Feels tough because: repeated steep inclines and descents, lots of stairs, remote feel despite reasonable distance.
Kitty’s Gorge (Extended Options) to Serpentine National Park
Distance ~14–21 km depending on loop
Elevation gain ~750 m (via longer AllTrails loop data)
Hard
There’s not a single official standard here. The basic path from Jarrahdale to Serpentine Falls and back is about 14 km on uneven terrain with some steps, but extended loops near Gooralong Brook can extend well beyond that — with elevation gains around ~750 m and rugged terrain cited on multiple trail references.
Feels tough because: length adds up quickly when you explore variants, rocky sections and creek crossings slow your pace, and the return uphill can be deceptive.
Longer, High-Elevation Challenges
These hikes are generally longer or involve sustained elevation gain that tests endurance as much as fitness.
Sullivan Rock to Monadnocks to Bibbulmun Track
Distance ~15 km
Elevation gain ~653 m
Hard
This is one of the standout day hikes for serious legs in the Perth hills region, following part of the Bibbulmun Track over twin peaks and undulating ridges. The combination of distance and elevation gain really separates this from shorter bushwalks, and hikers describe it as one of the more rewarding long hikes close to Perth.
Feels tough because: steady climbing, varied terrain, long underfoot time and exposure on exposed trails.
Sullivan Rock to Mt Cooke Summit
Distance ~18–20 km return
Elevation gain ~685 m (approx)
Hard
A longer alternative to the Monadnocks variant, this hike pushes you up to the highest point in the Darling Range at Mt Cooke. It’s a classic region hike with varied ground underfoot — from forest tracks to rocky ridges — and the sheer length combined with continuous climbing makes it one of the bigger day efforts you can do near Perth.
Feels tough because: long distance, sustained elevation and crumbly, uneven trail surfaces.
A Note on Gradient
Most local listings give distance and total elevation gain — which tells you how much up and down there is overall — but true gradient requires detailed topographic data that’s not standardised across local sources. Where flat km count and gain tell part of the story, gradient affects how that effort feels on your legs.
For example, a 12 km loop with 600 m of climbing feels dramatically harder than a flatter 15 km hike with the same total distance. That’s why we’re leaning on trail grade ratings and terrain descriptions rather than plain distances alone for this list.
How Hard Is This Hike Really?
Numbers are useful but they can lie. Two hikes might both be 15 km, but one is flat fire track and the other involves steep climbs, rock steps and loose footing.
That’s why I wrote a post that questions the reality of hiking difficulty levels, a deeper look at what truly shapes the difficulty of a hike beyond the numbers. If you’re picking your next challenge, it’s worth a read.
Choosing Your Challenge
These aren’t full-on mountaineering missions — WA just doesn’t have that technical alpine terrain that spoil North Americans and Europeans — but they are serious hikes by local standards. Each is uniquely challenging:
- Echidna Trail demands consistent heart rate and climbing ability.
- Numbat Trail tests your stamina and leg strength on uneven ground and stairs.
- Kitty’s Gorge combines distance with mixed terrain.
- Sullivan Rock variants reward endurance with broad views and ridge walking.
Fitness, planning and hydration matter here more than on easy loop walks. These trails aren’t for the faint of heart, and they reward respect for terrain and preparation.
Safety Notes
Because these hikes stretch distance and elevation:
- Start early in the day before heat builds.
- Carry plenty of water and snacks.
- Download offline maps and leave a clear plan with someone.
- Be mindful of fire danger days and summer conditions.
Even experienced hikers can find trails deceptively hard if they underestimate gradient or terrain difficulty.
Planning Your Hike (especially in summer)
- Start early: WA’s sun waits for no hiker. Begin at dawn to avoid peak heat and give yourself a full day of daylight.
- Bring plenty of water: Hydration is non-negotiable — at least 2–3 litres per person for longer hikes.
- Layer smart: Breathable, light clothing works best, but long sleeves and pants help with snakes, sun, and scratchy undergrowth.
- Know your trail: Some of the toughest hikes have unmarked sections — grab a paper map or download offline maps.
- Safety first: Let someone know your route, carry a snake bite kit, and consider a PLB or Garmin mini for remote hikes.
When to Call It
Even the toughest hikers know their limits.
Heat exhaustion, ankle injuries or unexpected weather (read: fires) can turn a challenging adventure into a dangerous one. Especially when hiking in summer.
Listen to your body, check Emergency WA alerts and remember: it’s better to return another day than to push past safe limits.
Coastal Alternatives
For those who want a tough hike without the bushfire risk or WA’s steep inland climbs, consider coastal trails. Something like Point Peron in Rockingham. The terrain is diverse, the ocean breeze keeps you cool and the views are absolutely spectacular at sunrise or sunset. You won’t get the stairburn of Numbat Trail, but a 3–5 km coastal walk with some undulating paths is a great challenge for a summer day.

From Paruna’s Numbat Trail stairs to rocky ascents at Sullivan Rock, there’s a trail to challenge every adventurous hiker. Just remember: preparation is everything. Check the weather, plan your route, pack smart, and get ready to earn every view.
