We came across this by accident when we were heading back home. So we checked it out. This was very cool. Make sure if you do this to check both sides of the road as you will see a waterfall on both sides.
To reach this waterfall exit the QEW at Victoria street (exit 57) and drive south. You will drive right past Balls Falls. A mile past that, turn left onto 8th Avenue and head east for 4 miles. 8th Avenue becomes Pelham Rd somewhere along the way. The Rockway Community Centre will be on your left.
across the road was the Small Falls above Bridge
