Smithfield Mountain Bike Park

For visiting riders the offer is rainforest singletrack on orange volcanic clay that drains unusually well, IMBA-graded green through double-black terrain (currently 36 mapped trails in our DB), and signature lines like the 4.3 km Pipeline climb (~300 m gain), the 2 km World's Downhill (the 2017 Worlds DH course, ~328 m descent), Centipede, Wobbegong, Stingers and the punchy double-black Happies. Trailhead facilities sit at the "World Cup car park" on McGregor Road with toilets, water, pump track, jump park and skills area; commercial shuttles run on demand via local operators because the climbs are long and steep.

Best Season & Conditions

• Peak riding season: June – October (the dry season; cooler nights, single-digit humidity for North Queensland, low rainfall)
• Wet-weather impact: Orange volcanic-clay soils drain well; higher trails dry fastest. Network rarely closes outright but expect slick roots, leeches and reduced grip after rain
• Fire-danger / total-fire-ban impact: No formal TFB closure policy on record — Smithfield's surrounds are wet sclerophyll/rainforest with limited fire risk in normal years
• Snow / alpine season: N/A — tropical, sea-level park
• Wet season (Dec–April): Cyclone season — riding still possible between storms but flash-flood and lightning risk is real. Daytime temperatures often 32–34°C with very high humidity; carry double the water you'd normally take [5]
• School-holiday surge: Busy during Queensland and southern-state winter school holidays (July) and around Crankworx week (late May); weekday rides remain quiet outside events

Managing Body & Trail Builders

History & Background

Smithfield is the closest thing Australian mountain biking has to a holy site. Glen Jacobs — a local Cairns rider who would later found trail-design firm World Trail — and a small crew of volunteers who called themselves the "Mud Cows" started cutting singletrack in Smithfield Conservation Park in the late 1980s, evolving from a club originally known as the Great Northern Hill Tribe into today's Cairns Mountain Bike Club. By the mid-1990s they had laid down a network sophisticated enough that the UCI brought a World Cup round to Cairns in 1995 — the first time a UCI MTB World Cup was held in the southern hemisphere. [2][7]

The 1996 UCI Mountain Bike World Championships followed at Smithfield (the 7th edition of the championships, and the first ever held outside Europe or North America). Jacobs was contracted as the UCI's first professional race-track designer off the back of that work and the company World Trail grew from there. [2][7]

After a long quiet period for Smithfield as a global venue, World Trail rebuilt the courses to bring the UCI World Cup back in 2014 and 2016, and the 2017 UCI Mountain Bike and Trials World Championships ran at Smithfield from 5 to 10 September 2017 on a 4.3 km XCO circuit with downhill on the dedicated DH course. The 2017 championships were Cairns' second hosting and Australia's third time hosting the championships overall. Switzerland topped the medal table; Australia placed third with two golds. Mick Hannah took silver in elite men's downhill and Tracey Hannah took bronze in elite women's downhill on home soil; Nino Schurter (Sui) won elite men's XC and Jolanda Neff (Sui) won elite women's XC. Loïc Bruni (Fra) and Miranda Miller (Can) won elite DH. [3][12]

In 2022 Smithfield was added to the global Crankworx World Tour, alongside Whistler, Innsbruck and Rotorua — Crankworx Cairns ran 5–9 October 2022 and returned in 2023 and again 21–25 May 2025 (after a hiatus in 2024). Smithfield also hosts the UCI Masters MTB World Championships annually around the same window (2024 and 14–18 May 2025), drawing riders 35+ from dozens of nations. [4][6]
