Old Mans Valley

Old Man’s Valley MTB Trails – Hornsby Hornsby Mountain Bike Trail, better known to Sydney riders as Old Man’s Valley (OMV), is a purpose-built mountain bike network tucked into the bushland below Hornsby town centre in Sydney’s north. One of its biggest advantages is accessibility — you can be on genuine MTB singletrack within minutes of Hornsby Station and the surrounding shops. Hornsby Shire Council describes the official network as around 6km of purpose-built MTB trail, while current Trailforks mapping shows a broader collection of approximately 23 MTB trail sections around Old Man’s Valley. There’s a surprising amount packed into the valley, with green, blue and black-rated riding, climbing trails, technical descents, flow sections and a jump area. The terrain has a distinctly Sydney feel, combining sandstone rock, tight singletrack, bridges, drops, rock faces, berms and technical features. Popular trails include Lava Flow, Intermediate Trail, High Line, Stage 1 Black Descent and the Green Loop. Lava Flow is one of the standout flow-style trails, while the black descent adds drops, jumps, rock faces and other features for experienced riders. Newer riders can stick to the easier green options before progressing through the network. OMV’s compact layout makes it particularly good for session-style riding. Rather than heading out for one long loop, riders can climb back through the network and repeat different descents, practise features or combine sections into a longer ride. Its location also makes Old Man’s Valley one of Sydney’s most convenient MTB destinations. Hornsby Council specifically highlights that the trails are only a short walk from Hornsby Train Station, making this a rare Sydney MTB network that can realistically be reached without a car. For riders searching for Old Man’s Valley MTB, Hornsby mountain bike trails, OMV MTB, mountain biking in northern Sydney or MTB trails accessible by train, this is definitely one to have on the ride list. RTS Tip: Old Man’s Valley packs a lot into a relatively small area, so don’t judge it purely by kilometres — the fun comes from linking and repeating the different trails. Current mapping shows everything from the Green Loop through to black descents and technical features. Check individual trail status before riding, as sections can close independently for maintenance or trail conditions.
