The canyon was really cool, but crowded. There were lines by each of the falls viewpoints to wait to take your picture (about 2pm weekday), and some folks seemed completely oblivious to moving with the flow of traffic on the narrow walkways. Once you get past the upper falls, the crowd thins out a ton and it's a nice quiet hike to the ink pots. They were pretty cool and the surrounding views were nice, but if you're limited on time, I wouldn't consider the ink pots portion of the hike a must-see. Definitely go up to the upper viewpoint though.
