River Runs Through It is a popular trail among locals and visitors looking to experience mountain biking resembling the Shore. Best described as an all-mountain and x-country trail, River Runs Through It is divided into two sections; River North and River South. Both sections have different approaches and are commonly linked together via Bart’s Dark and Alta Lake Road.

River North is an Expert trail, consisting of larger roots, rocks, man-made bridges, stunts and skinny’s. River South is an advanced trail, with a few expert options, consisting of more man-made stunts, ladders and bridges. We found River South a bit more manageable and enjoyable. River North will push the advanced and expert rider with its technical, short and steep sections onto wooden features and skinnys.

Warning: this trail should be avoided after heavy rain, as the trail is super slippery when wet. All features become super gnarly after heavy rain.

River South – The entrance is well marked and located in the Rainbow Park carpark.

River North – Located just off Alta Lake Road past the big bend where a gravel road breaks south. Take the gravel road for about 100 metres to the start of River North trailhead – clearly marked.

We really enjoyed River South, a more manageable trail for the accomplished rider. Also, it offers a greater number of wooden features; varying in ability. If you’re short on time, stick to a loop on River South.

River South will be enjoyed by intermediate riders looking to work on their technical riding. River North is far more challenging with little options to ride around the steep, rocky and rooty terrain.
