Hello,
There's a couple places around Regina to ride, most of the sand pits are fenced and posted
.
There's Regina beach it's fun to ride, there sand, quad trails, some tight single tracks but hidden well. There's wide open 4x4 trails through the hills. Go to Regina beach and when you get to the stop sign go straight, you'll see the trails.
Another place but the cops might show up is behind ecolle electric there is a little track. If you follow the rail tracks to the edge of city there's a trail that goes all the way to balgonie.
