Here is a trail loop I did around Nellie Mcclung park and the Saskatchewan drive trail. It was quite beautiful on the Nellie Mcclung side with the trees as a canopy, and the Saskatchewan Dr side was quite nice as well with trees on one side and a busy road on the other. On the whole it took me an hour to walk, that's including all the many wonderful photo opportunities.
Accessibility: I started the trail from the north of the [P] parking sign because that's actually private property, so I parked in the neighbourhood just north. There were a few asphalt entrances to the trail from that location that looked pretty wheel friendly and it does stay asphalt for a bit to the south but there is uneven cement in patches and this time of year it got pretty icy, I almost ended up on my butt even with a pretty good pair of boots so be wary.
Difficulty: When I got close to the kinsman and looped up to Saskatchewan drive there was a pretty big hill I had to climb, it wasn't part of the trail but after looking a round a bit I found the trail pretty easily. The hill was maybe a 7/10 for difficutly but the rest of the trail was either flat or a decline. At the start like I mention there were a couple hills but I'd rate them more of a 4-5/10.
Tips/tricks: I kept my phone going by plugging it into my laptop which was in my backpack, that way I had more than enough power to take lots of pretty pics and catch some Pokemon (that's right folks, l'm a #nerd)
