This place caught me by surprise. Its about two thirds doubletrack / one third singletrack winding round some small lakes and up the side of the Niagara Escarpment. Its essentially a few shorter trails that loop totalling 10-11km. Its beautiful countryside and the double track is totally beginner friendly and would keep an intermediate rider happy too. The green trail (cliff top trail) does need more skill and experience though. This single track trail starts off windy and relatively smooth before you're suddenly presented with a rock garden that would intimidate the beginner, shortly after which you drop down a steep switch back between and over boulders. A good technical challenge!
Anything "scary" is totally walkable/avoidable and so its a really good mix of beginner friendly and entertaining for the more experienced rider who will want to crank out a few laps.
Tip: Ride the loop counter clockwise from the main parking lot.
