Greenvalleys is a privately owned, member-driven gravity / freeride / slopestyle mountain bike park in the foothills of the Illawarra escarpment at Tongarra, NSW — roughly 20 minutes inland from Albion Park and ~90 minutes south of Sydney. It markets itself as "Australia's boutique mountain bike playground" and is heavily skewed toward intermediate-to-expert downhill, freeride and jump riding, with a progressive Skills Park, more than 50 wooden drops/ramps across the trail network, a 4 m airbag and the headline Pro Line big-mountain trail.

The park is run by Greenvalleys Mountain Bike Club (private, AusCycling-affiliated) and reportedly has around 1,500 members, making it one of the largest gravity-focused MTB clubs in the country. Access is gated: members get unlimited push-up riding during daylight hours on non-race days, while non-members can only ride on pre-booked Social Gravity Days, Leg Saver shuttle days or event days. There is no chairlift or cable car — uplift is by a shuttle bus on scheduled days; otherwise you climb the internal fire road (~20 min push/ride). ()
Greenvalleys is the spiritual home of slopestyle MTB in Australia. Operator Nick Haertsch funded the national slopestyle tour out-of-pocket for three years, and in April 2024 Greenvalleys hosted the inaugural AusCycling National Slopestyle Championships — making Australia the first country with a national sporting body recognising the discipline. The park has also hosted the 2021 Gravity Enduro National Championships, multiple NSW State Gravity Series rounds and the 2025 AusCycling NSW/ACT Downhill State Championships. ()
Greenvalleys grew out of Nick Haertsch's long campaign to establish gravity / slopestyle MTB facilities and recognition in Australia. Notable milestones:
The park sits adjacent to Macquarie Pass National Park; the land is dry sclerophyll forest on the western edge of the Illawarra escarpment.
