Big rides have big rewards. From coast-hugging trails to forest epics, WA’s longest MTB rides are built for riders who crave distance over dynamics. Here are a few of our favourite long WA MTB rides.

There’s something about a long ride that just hits different. The further you go, the more the noise drops away—until it’s just you, your bike and the trail ahead.

Western Australia might not be the first place you think of for endurance riding, but if you’re keen to test your legs (and maybe your patience), there are some seriously good long-distance trails out here. Whether you’re skimming the coastline or winding through karri forest, these rides give you that slow-burn satisfaction that only comes from covering serious ground.


Long vs Dynamic Trails—What’s the Difference?

It’s easy to get caught chasing jumps and berms, but longer trails ask something different from you. They’re less about tricks and more about time in the saddle. Endurance, pacing, and a willingness to keep going when the novelty wears off.

If you’re someone who wants to sink into a ride, not just blast it out, these are the trails for you.

1. Munda Biddi Trail (1,050 km)

  • Start/End: Mundaring to Albany
  • Why it’s epic: It’s one of the longest off-road bike trails on the planet. You’ll ride through towering forests, sleepy towns, coastal bushland, and everything in between. Most people do it in chunks, but there’s a growing crew of legends who take it on end-to-end.
  • Good for: Bikepackers, tourers and anyone with time to spare and a craving for the long haul.

2. Kalamunda Circuit (22 km)

  • Location: Perth Hills
  • What it’s like: The terrain throws a bit of everything at you—tight corners, rocky drops, lung-busting climbs, and flowing downhill runs. It’s well-maintained and easy to access from Perth.
  • Good for: Confident riders who want a solid loop with proper trail feel. Not massive in distance, but enough to leave your quads humming.

Forest Tracks That Just Keep Going

4. Relentless Blue – Pemberton (9 km loop, repeat as needed)

  • Location: Pemberton MTB Park
  • Trail vibe: Shaded singletrack with tight corners and a few punchy climbs. It’s a loop—but string it together a few times and it becomes a proper test.
  • Good for: Intermediate and advanced riders chasing rhythm and stamina in the forest.

5. Carinyah Trail (15 km)

  • Location: Near Kalamunda
  • What to expect: Steady gradients and open bushland riding. It’s less technical, more meditative.
  • Good for: Beginners working up to longer distances, or anyone keen for a cruisy escape.

Coastal Rides with a View

7. Wadjemup Bidi Trail Network (45 km total)

  • Location: Rottnest Island
  • What’s different: It’s not a “mountain bike” trail in the purest sense, but it’s long, unique, and full of character. Think beach crossings, WWII ruins and quokkas.
  • Good for: Families, casual riders, and anyone planning a slow, sunny day out on Rottnest Island (maybe when the fish aren’t biting or if you can’t find a good crayfish spot).

Big Rides in the South West

8. Mount Lennard (40+ km combined)

  • Location: Wellington National Park, near Collie
  • Terrain: Fast, flowing singletrack that links together into custom long loops. Some technical stuff too.
  • Good for: Fit riders wanting to mix trail fun with endurance gains.

9. Denmark to Nornalup Rail Trail (54 km)

  • Location: Denmark, heading west
  • Trail type: An old railway line turned mellow gravel path. It’s flat, scenic, and ideal for watching the countryside roll by.
  • Good for: Bikepackers, families or a relaxed day ride with a picnic stop.

What to Bring on a Long Ride

Before you roll out, double-check you’ve got the basics sorted:

  • Hydration pack or water bottles (it gets dry out here in WA)
  • Energy snacks—bars, gels, nuts, whatever fuels you
  • Tube, pump, repair kit (punctures love long trails)
  • Bike shorts with padding (thank us later)
  • Sunscreen and sunglasses
  • Offline maps or Trailforks loaded up
  • First aid kit and a way to call for help if needed

In It For the Long Haul

WA isn’t all desert and distance—it’s full of underrated trails that reward patience, persistence, and a willingness to go beyond the usual loop. Whether you’re chasing solitude, training for something big, or just love seeing new landscapes from the saddle, these longer rides hit the sweet spot.
