The first time I did the Salt, we did 3 hikes. My favorite was up Yankee Joe Canyon (on the left somewhere between Blackrock and the Maze). It was a cool little box canyon hike with some tricky little bouldering style spots to get up and some cool flora. We camped at the mouth of the canyon and it was a bitchin' site but when we went by two weeks ago, it appeared that the floods had demolished any worthwhile camping spots. Didn't hop out to look around though.
We did a pre-dawn hike up Cherry Creek as far as we could get. Watching the sunrise on the saguaro's was sweet but the hike was a bramble-fest and we ultimately didn't make it more than a mile up with about 3 miles of wandering around looking for passable routes. I wouldn't recommend this one (though, again, floods could have changed things drastically). Again, we camped at Cherry Creek (it was a sweet site but schlepping the gear across the creek was a pain) but when I looked at it this time around, the sandy bench we camped on was completely gone and eroded down about 10'.
We did a third hike up a short little canyon on the right about 15 miles above the take-out (can't remember what it was called, it's marked as a good hike on oarboatman's maps, maybe he'll be able to tell us what it is). It was also a lot of navigating through brambles but was totally worth it as at the end you get to a big headwall with a waterfall coming over. Also a had some decent camping spots by the river.
