I was excited to see the waterfall, but I definitely had way too high of an expectation for it because after all that walking... it was a little-lot disappointing.
The path is all pretty much paved or cleared. It's really just a long walk. It is super dog friendly. Watch out for the bikers and runners.
This is great for a walking trail (not hiking). We went with our dog and had a nice stroll. The offshoots from the trail are nice and we got to explore a part of the river. It was fairly crowded on a beautiful Sunday late morning. The trail is flat or paved and wide on the main stretch to the falls at least (we didn't do the entire loop).
