The Gap Creek Reserve is part of the Mount Cootha region parklands which includes a vast network of interconnecting trails and parks. The best place to start your mountain biking is at the Gap Creek Rd carpark.
Once you arrive at the carpark continue over a wooden bridge where you will find a large map to plan your journey. There are a variety of different walking and biking trails for different levels of skill. There is also a nice park here with many facilities including toilets and barbeques - great for a picnic!
