I didn't do fins and things when I was there last year, but we did do Hells Revenge. The horseshoe overlook of the Colorado River on hells Revenge was pretty cool.Fins and Things plus the 4x4 trail to Tower Arch in Arches is a good long day and doable in a stock Jeep and plenty of fun for the family. Tower Arch doesn’t get much traffic because it’s a good hike to get to it or a couple hour drive via the off road trail, so it’s mostly desolate and avoids crowds. Hundreds of people fighting for parking spots at the typical tourist spots but Tower Arch, we saw 3 people all day.
I’d recommend at least checking out Grandstaff Canyon Trail if you like a moderate hike that is kid friendly. Spring fed below source of the creek that is just 100’ below Fins N Things. Neat and different perspective from nearly the same spot on the FNT trail above the canyon.
Lots of other cool spots as well, Canyonlands included.
We did the tower Arch trail and that was definitely on my list with the rental.
Vegas is only on the list as the exit point for GC and Hoover Dam. If we have to do a loop, we'd drop that.
And Albuquerque is on my radar.
