Monkey Wrench is a relatively short trail with and very little climbing. It's key features are the gently winding trail intro that passes through managed pine forest, a heavy rock and root section in the middle, and a slight climb out through managed pine forest at the end. It's a quick trail with just enough stumbling blocks along the way to challenge the beginner rider or make the experienced rider pay attention as they go for another KOM. The trail was modified by GORBA a couple of seasons ago, adding the new intro section, and retiring it's original entrance to prevent damage to the Guelph Lake Levee.

The intro section of the trail is a good warm up. It's relatively flat, and smooth, allowing riders to maintain their speed. It should also be mentioned that the turns in this section of the trail have a big enough radius that you don't scrub off all your speed going through them. The only real challenge to keeping your speed through this section, is the occasional build up of pine needles (needle bearings) and pine cones.

The middle section of this trail is what people find to be most challenging, and the part which raises this trail to the "Intermediate" class from "Easy". Upon exiting the pine forest intro, you'll find yourself facing 200 to 300 meters of root surface. A narrow (12-14" wide), eight foot long bridge lies mid-point in this section. The bridge entrance is marked with roots and new riders often find it hard to pick their line getting onto the wood. The bridge is low, with no more than two feet from the deck to the water and grass below, but the "line confusion" makes it appear like more of a monster than it really is. Once over the bridge, you've got another 100 meters of straight run through roots and rocks until you enter the final phase. It should be noted that this middle section of the trail is low lying and gets swampy in wet weather. If it's been raining at the GORBA trails, don't bother trying this one. You'll get mucky, and likely cause trail damage.

The final section of the trail passes through pine managed forest again. This section of the pine forest is a little more rooty than the trail intro. It also has a slight rise to it, giving an added challenge if you're really pushing to best your time on the trail. It does not pose a serious technical challenge, so it give some reprieve for the beginner riders who are looking forward to the open smooth surfaces ahead.

Access Info

If you are trying to find the entrance to Monkey Wrench, look for Kaine Hill Drive on Google maps. The extension to Kaine Hill Drive (blocked to car traffic) becomes the paved path along the Guelph Lake Levee, also called "The Saddle Dam" by locals. The entrance is on your left, just passed the traffic barrier.

If you are entering the GORBA Trails from Victoria Road or Conservation Drive, follow Grand Trunk east from the main Guelph Lake dam. Grand Trunk will take you right onto the Saddle Dam. Then you just have to follow the pavement, The entrance will be on your right. If you get the houses on Kaine Hill Drive...you've gone too far.

       We have closed the fall line section of the trail and moved the entrance further east off Kane hill, the GRCA asked us to do this to reduce erosion on the saddle dam. Despite our efforts all the closure signs and trail blocking keep going missing or pulled aside.

       So the downhill blast from the dam is now closed?

       That is what we are trying to do, the intitalled feel it should stay open for their slefish plesure so the game continues.
