Dufferin Forest is an excellent LARGE forest west of Barrie just at the top of a hill. It’s a bit far from Toronto but worth the drive. Never crowded and with plenty of parking too.
The trails flow most of the time from one into the other. There are few signs in this large woodlot and you could get lost. After a rain it drains well. It is rated Advanced only if you ride more the 25+ km then you will need good legs.
Most of the riding is at the top of the hill, so stay there. If you go to the bottom of the valley it will be a good work out upon your return. Lots of trail to ride but aside of the view south off the hilltop it’s all trees, not that scenic and no outstanding features, which is good reason to not get lost, cause you might. Complete maps are hard to find and I hope to put one together eventually.
You may have to walk part of the hill, it is sandy. The terrain drains well, so riders favour it sooner after a rain than other spots. You will find it a mixture of hardwood and pine tree farming by the government.
There are a no rock or wooden structures I can recall, few open sections. Some caused by logging that may change the trail up. You may even see deer or horses. Give them notice you are coming.
This wood tract is just north beyond the Mansfield Nordic area. That used to be a MTB area too, but now only hosts races.
An excellent forrest run for seasoned MTB riders looking to ride long and hard. Plenty of twisty single track that never gets boring.
