Princess Falls, both upper and lower in Hamilton can be seen directly on the Chedoke Radial Trail, so the access to view is easy peasy.
The water system for this flow of upper to lower is unknown, so as a point of interest it has been featured a cascading waterfall in Hamilton. The Upper Princess falls is about 130 metres high, but rarely has a flow, as the lower princess or simply "Princess Falls" as depicted in this picture I took is a 7 metre high ribbon fall. Most flow will be seen in the winter thaw in the spring which will dramatically improve the water flow, but take it from me although it is considered the second highest waterfall in Hamilton, it doesn't get much notoriety due to it's location. Frankly it looks like nothing much more than a water fountain.
