Cornubia Forest Park

Overview

Cornubia Forest Park is a 196-hectare nature refuge ~25 minutes south of Brisbane CBD in the City of Logan, sitting on Turrbal country. It is one of South-East Queensland's biggest cross-country mountain-bike networks: just under 20 km of hand-cut and machine-built singletrack plus ~5 km of fireroad, with a green/blue/black diamond difficulty mix. The trails run downward from an upper ridge, making most rides effectively shuttle-laps without a shuttle — riders climb up the West Mt Cotton Road fireroad link, then drop in via narrower, steeper trails than most of SEQ. (AMB Magazine described the hand-cut singletrack as "narrower and steeper than in other parts of South East Queensland.")

What makes Cornubia distinct is its connectivity. From the upper escarpment the network links via the Nirvana trail into Daisy Hill Conservation Park, and via Kimberley Forest Park toward Bayview Conservation Park — riders routinely string the three together into multi-hour loops. The build style favours rock gardens, angled log-rollovers, and discrete double jumps over flow-mat berms; it rewards intermediate-to-advanced riders looking to progress, and the AMB rating puts technicality 3/5, fitness 4/5, and overall trail-quality 5/5.

There is no commercial hub on site. The main trailhead is an unsigned step-over at the end of Kimberly Drive (off Plantain Road, exit 28 from the M1). A second access from Parkview Crescent suits riders who want to finish on a downhill (via the "Flowmy Loamy" descent / Parkview Access Trail). Trails are maintained by LCTA-Cornubia (Logan Community Trail Care Alliance), a volunteer group working in association with Logan City Council.

Location & Access

• Address: End of Kimberly Drive, Cornubia QLD 4130 (primary trailhead); secondary access at Parkview Crescent, Cornubia. Council street address for the reserve is on West Mt Cotton Road.
• Region: Logan / South Brisbane (current DB value retained)
• Drive times: ~25 min from Brisbane CBD via M1 (exit 28, Shailer Park); ~45 min from Gold Coast.
• Public transport: No PT to trailhead — car only.
• Parking: Free street parking at the end of Kimberly Drive (step-over entry) and at Parkview Crescent. No formal sealed bays; gravel/road verge.
• Coords: -27.606998, 153.154039 (current DB value verified against Logan Council and Trailforks region centroid).

Best Season & Conditions

• Peak riding season: Autumn and spring (Apr–May and Aug–Oct) — cooler temperatures, lower humidity. Brisbane's shoulder seasons are explicitly recommended by AMB.
• Wet-weather impact: Drains relatively well, but the blue trails (Wallum Froglet, Ginger Gully, Stupidly Happy) feature angled log-rollovers that become slippery when wet. No formal wet-weather closures, but riders are asked to avoid trails when soft to protect surface.
• Fire-danger / total-fire-ban impact: No formal MTB closure on TFB days; park itself stays open but extreme conditions may bring Logan Council closures.
• Snow / alpine season: N/A.
• Summer: December–February is hot and humid; trails ridable but typically early-morning only. Encounters with snakes more likely.
• School-holiday surge: Weekends busy year-round; no shuttle bookings to manage.

Managing Body & Trail Builders

• Land manager: Logan City Council (also a registered Koala Nature Refuge under agreement with the Queensland state government; part of the Australian National Reserve System).
• Trail builder / maintainer: LCTA-Cornubia (Logan Community Trail Care Alliance), in association with Logan City Council. Volunteer trail crew.
• Volunteer / dig days: Monthly+ trail care events (e.g. Aug 2025, Oct 2025 listed on Trailforks). Meeting points at Sugarwood Place or on-trail. Coordination via LCTA-Cornubia Facebook page.
• Donations / membership: No paid membership for LCTA itself; RATS Cycling Club ("Racing, Advocacy, Trail Care, Social") is the affiliated regional club and promotes Cornubia trail care.
• Council general line: 07 3412 3412.

History & Background

The Cornubia Forest Nature Refuge was created over an extended land-acquisition program by Logan City Council, purchasing parcels between 1999 and 2010 to assemble the protected area. The refuge comprises two sections: the former Cornubia Forest Park to the south and the Cornubia Escarpment to the north — together totalling 196 hectares (480 acres) of bushland and ridge.

The reserve was historically part of large 1920s-era farmland — timber-getting, dairying, and crops of corn, oats and barley — before progressive subdivision and the council's conservation purchases. The refuge is gazetted under a Koala Nature Refuge Agreement with the Queensland Government and is included in Australia's National Reserve System, which constrains land use to conservation-compatible activities — mountain biking is permitted as part of the management plan.

Mountain biking grew here through informal hand-cut trail building in the 2000s and 2010s, with steady formalisation under LCTA-Cornubia and Logan City Council. The current ~20 km network is the result of that long-term volunteer-led build effort, with progressive machine-built additions (notably the Parkview Crescent side) and infrastructure upgrades (shelter, seating, toilets, drinking water) added under Council's Local Infrastructure Program after 2020. The site provides habitat for koalas, bandicoots, water dragons, wallabies, greater gliders and ~50 species of native birds.
