Hi
There is a marker at the very tip of Point State Park
That marks the confluence of the three rivers. That's a good spot for pictures
And a symbolic start to the journey. However you can't drive your car into point state park. I would suggest temporarily parking in front of the Wyndham on Commonwealth Place. At off- peak times of the day, this street has light traffic.
