Popular for mountain biking and horse riding, Heath trail is a challenging fire trail running down into the valley of Garigal National Park. It's a fantastic ride and suited to more experienced mountain bikers. There are sandy corners and the terrain can be rough, so take care. Of course, if you ride down into the valley you'll have to ride back out - the climb can be hard work, but it's definitely worth the effort.
Heath Trail merges into Bare Creek trail shortly after entering Garigal National Park. Bare Creek runs along the east side of the creek, passing Quarry trail at the first creek crossing and eventually adjoining Cascades trail, so there are plenty of options for extending your mountain biking adventure. It's a great track to walk as well - watch out for other track users.
