Warrimoo's history

The Warrimoo Downhill Mountain Bike trail is a highly valued downhill series of trails with a long history. Initially an informal mountain bike trail, Warrimoo (or "Crackers" as it is known in the mountain biking community) was closed by Ku-ring-gai Council in 2017 to protect the Coastal Upland Swamp identified within the area.

Council commissioned an ecological feasibility study to determine if there was a way to protect the bushland whilst still allowing the community to continue to enjoy recreation in this natural area. Council has worked closely with consultants, track builders, State agencies and the community to find a sustainable option to provide a continuing downhill mountain biking experience.

As a part of the wider Recreation in Natural Areas Strategy, Council consulted with mountain bikers, environmental groups, ecologists and residents to ensure all user groups could enjoy our bushland with minimal impact.

The mountain biking community worked together with Council to construct the Warrimoo Downhill Mountain Bike Trail and our 'Moo Volunteers' continue to work to maintain it. Show your respect by observing the rules and contact Council if you want to be part of the volunteer crew below.

Trail rating

The trail is broken up into sections. It consists of a small beginners loop and a 600m two-way double black diamond rated downhill trail with an associated return climb route. This means it is for skilled and experienced riders only. Ride within your limits!

Trail status and use

Ku-ring-gai Council and the local community welcome you to this site and ask that you follow guidelines to help protect the site and its biodiversity, ensuring that the experience of downhill riding is able to be enjoyed by everyone.

Due to the nature of the trail surface, Warrimoo may be closed for maintenance requirements or due to inclement weather including rain. The park will be signed if closed. Do not ride wet trails.

Mountain biking is an exciting and popular sport and downhill trails are one of the most popular and exciting styles. This trail offers skilled riders the opportunity to experience a world-class downhill mountain biking experience in an incredible bushland setting.

Mountain biking is a highly dangerous activity - keep yourself and others safe and ride within your limits.
