Environment Minister Albert Jacob said the new $270,000 trail formed part of the first purpose-built trail network under the Liberal National Government's South West Mountain Bike Master Plan, made possible by the $21.05 million Royalties for Regions Parks for People initiative.
"Mountain biking is growing in popularity, increasing the demand for access to our national parks," Mr Jacob said.
"The master plan identified this area as a priority for purpose-built trails and construction of the new network has already attracted significant local and visitor interest.
"The Bramley forest network incorporates trails with varying levels of difficulty, appealing to a broad range of people, with smooth, flowing trails for beginners to more technically challenging trails for experienced riders.
"Under the master plan, the State Government is also working towards creating world-class mountain bike trails throughout the south-west, including in the Collie and Pemberton areas."
The Department of Parks and Wildlife is working with the Shire of Augusta-Margaret River and Margaret River Off Road Cycling Association to develop more trails within Bramley National Park and adjoining State forest and shire reserves.
Regional Development Minister Terry Redman said Parks for People had improved recreational infrastructure such as bike and walk trails and camping areas across WA's regional national parks.
"Investing in sustainable nature-based tourism and recreation helps to strengthen regional economies," Mr Redman said.
"Royalties for Regions is about supporting and growing our regions and I look forward to seeing this investment bring social and economic benefits to the local community."
