Not a motocross track but a good area to go for a ride, lots of ATV's and Dirt bikes there. The Venca Bridge area, to get here head north on highway 21 straight through Fort Saskatchewan, the highway becomes highway 15 once you exit the Fort. You will pass a Gas station/restaurant on your right (country boyz), the next turn is only a couple of km past this. Turn left on the next secondary highway on your left (north). Hwy 830. Then head north down that highway this is probably about 8 - 10 minutes down this road on your right, You have to go under 2 sets of overhead wires once your past there your close, keep an eye in the right (east) ditches for sand and trails, theres will be a big sand area where those trails are, turn right down that gravel road and follow it (east) it will turn to the right (south) go down that road about 2 km and on the left there is a large staging area and most likely alot of vehicles..
One you can go to for practice in at Castral Speedway. I haven't been for a couple of years but it used to be open on Tuesdays and Thursdays for any one, not sure if u pay or not. Track is located staight west of NIsku, exsit off Hwy 2, keep looking left, can't miss it.
