Bob Gnarly is an expert (double black) downhill run located in the Mackenzie Area. It is split into three distinct parts, separated by the Mackenzie FSR and then again by the Waco Connector. This trail will frighten even the most accomplished rider when ridden from the proper trailhead located off of Overnight Sensation. Personally, I would avoid the first section and stick to riding the remaining two, which see a lot more use and are in better shape.

The first section of trail, accessed via Overnight Sensation is extremely gnarly. It’s very rugged and rough. Steep slabs that haven’t seen much action pointing down some crazy lines consisting of super loose and sketchy rock will alarm most, or at least have them clutching their cheeks as they drop in. There are several large downed trees lying across the trail to watch out for; clearly they have been there for a while. Ride Overnight Sensation for about 350 metres until you pop out of the trees onto a distinctive rock bluff – Bob Gnarly begins on rider’s right and is not marked. Unless you like to torture yourself and have no fear, I suggest you ride section two and three only.

Section two is accessible directly via the Mackenzie FSR, up 3.2 km from the Gravel Pit parking lot. This section of Bob Gnarly contains remnants of old skinnies over downed logs and a few sketchy, not recommended for riding, TTFs. Aside from one TTF that gaps the creek, a fun gap, the remainder are no longer suitable to ride. The overall nature of the trail is fast and steep, with several sections leading down loose sandy dirt.

The last section is a walk in the park compared with section one and two. It’s also the shortest section, about two hundred meters of nice and flowy singletrack. The trail ends at the lower Waco Connector, just above Happy Trail. Once on Waco, turn left to hit up Lower Mackenzie or right to climb back up Waco to the plethora of trail options that await you there.

Section one also known as the main trailhead for Bob Gnarly is accessed via Overnight Sensation, located about 350 m down the trail once you pop out of the woods onto a well-defined rock bluff. Look for Bob Gnarly to drop down the steep slab to rider’s right.

The second trailhead, used by most, is found along the Mackenzie FSR 3.2 km from the gravel pit. Look for the trailhead on the left of the FSR marked by cairns.
