Too bad about the gravel; I know the township that part of the trail goes through is not rolling in dough and only goes through one of its small communities, so perhaps it is good that it wasn't left to go back to nature.
In all fairness to the township, they're not the only ones to have done this. The Cottontail Trail is similar. There's a problem not just with the local authority, it's also with Trans-Canada Trails, who fund these to the tune of (50%? IIRC) and the grant may also be matched by a federal plan...but *there's no oversight*! I was just going to link to the Cottontail Trail, with only my word to make my case, and lo and behold, here's a Youtube vid:
It's two years old, my first encounter with that trail was when the large gravel went down about five years ago. Impossible to cycle with stability, let alone high likelihood of a flat, even with Kevlar protected 28c tires. It looks like the stone is starting to sink into the clay somewhat in spots, but I always cycle through that alignment on an adjacent back road, paved, to connect the Elora Trail (which is exquisite to this day, albeit needs some TLC) to the Kissing Bridge Trail (ditto, albeit some sections continue in good shape, others not).
The bottom line is that the Cottontail Trail was far better when it was just a dirt track along the abandoned road RoW. I traced funding on the gravel some years back, and it's more for the local farmers to access their fields than for the benefit of hikers/cyclists. For Oro-Medonte, the emphasis is on Skidoo RoW. It's an absolute shame, and possibly misappropriation of funding. Or worse...
On the other hand, some trails are very well taken care of, with exactly the right grade of crushed limestone, some with a polymer binding in it. The Caledon Trailway in many sections is exactly that, very fast, stable and an absolute joy. How bad is some of the other gravel sections on other trails? You couldn't even use a motorbike on them safely, it's that loose and unpredictable. And if you go down...you're going to be damaged.
To tie this back to the topic surmise, The Kissing Bridge Trail can be accessed with a thirty minute ride from the 29 bus terminal in Guelph (Guelph is working on a connecting bike path to improve that) or the 25 bus in K/W and take two GRT buses, the latter the Elmira one which connects almost right to the trail at its northern end. There's quite a few very good trails that GO brings you close to, but not quite there. The Cambridge to Hamilton one is accessible by GO and local connections in a number of spots.
One of these days I should compile a webpage on how to do it since Metrolinx and the Ont Min of Tourism seem unable to. Oddly, the one train GO does 'host'...to Niagara Falls, is one of the most stranded destinations! I guess it's good for those that need a cloistered day out, but Uxbridge and Peterborough offer much more robust opportunities. Actually
@ShonTron would be the man to approach QP and present the concept.
