My wife and I have a trip coming up in late September to visit the Needles. Our plan was to arrive at Squaw Flat -> Lost canyon -> Druid Arch -> Chesler Park -> Squaw Flat. This would leave out the Squaw flat loop. The question that I have is whether Lost canyon is worth the extra day or not, as there doesn’t seem to be much info on it. I only have 4 days, so I was wanting to consolidate some pretty cool hikes in the Needles or between the Needles and SLC airport without wasting time on the decent hikes.
