Conroy Pit is a very popular off leash dog park within the south-east part of the Greenbelt, but it is also a great place to explore by bike. Here are a couple of routes to get there and back from Centretown.
Getting to the corner of Hunt Club Road and the Airport Parkway off ramp alon gthe blue route is pretty safe, however the next section along Hunt Club and Bank Street was hell. Speeding traffic weaving in and out of four and six lane traffic with no shoulders at all, that kind of hell. So I recommend following the much safer red route I took to get home. More on that later.
I accessed the park at the north west entrance where Quail Run Road ends, like so.
Once in the park the ground is pretty much packed sand everywhere, with a few loose spots, but nothing too difficult to negotiate on a hybrid bike. It would be a sinch on a mountain bike.
There is indeed a pit, on one side of which is a hill used for tobogganing in the winter.
There were a number of dogs running free along the path so I proceeded at a very comfy careful pace lest they decide to charge on over to say hi, or dart across the path after each other. I think there is an unwritten rule you don’t take aggressive dogs to an off leash park. All the dog walkers were very friendly as well, and, by all indications, very good at picking up after their pets so don’t worry about that.
There are also lots of small paths not plotted on a map that you could spend time discovering without worrying about getting too lost, as the park is pretty contained.
The south eastern part is more wooded.
Heading back to town I followed the bike lane along Conroy Road. It’s a busy commuter artery, but the bike lane was great for getting me safely all the way to Walkley Road.
At Walkley I hopped onto the bike path that runs along the Killborn Allotment Gardens, and then wove my way home along the route hi-lited in red. Et voila. Being in the pits can be fun!

I should think that dog-walkers could get away with leaving their pets “packages” lying about in a place like this. So cudos to them for picking up.
I think there’s some peer pressure policing going on. That and there’s a huge purpose built bin in the main parking off Conroy, so folks have somewhere to drop their pet packages other than in the middle of the park.
