Just doing some google earth travelling last night in the HRM.
I notice that you guys ride near some lakes. Would this be the area?
The trails you see on Google maps in that location are off limits to bikes from what I understand. They lead off the Bayer’s Lake Trail which runs from Joseph Howe across from the Super Store all the way out past exit 5 on the 102. It’s the old rail bed so it’s pretty level and covered in fine gravel and is a multi use trail so bikes are welcome.

Zuki this Strava heatmap shows where people tend to ride the most.
Trails around HRM that are very popular are.
