Was going to be in Rattlesnake Canyon that Sunday, but decided it is too wet and the road in and out is totally impassable when wet.
As for a Sunday trail....
I have two in mind...
1. White Rim Trail. Fantastic views, but 110 miles long (that is the off-road part and does not count getting to the White Rim Trail. So it is about 9 hours. NEO and I did it a few years ago, left at 7, returned about 5, and after being closed for almost the entire year, it was finally re-opened last week. Mother nature has not been kind to this trail.
2. Potash, White Rim (part of) down to Lathrop canyon and have lunch down on the CO river. This would encompass hwy 279 to Potash road to the start of the White Rim Trail, then on to Lathrop Canyon trail down to the river. Some fantastic views and great photo ops, a great place to line up the Hummers for a group shot (Goosenecks overlook), Musselman Arch (if you ever wanted to walk across an arch, this is the place) and then down the Latrhop Canyon trail to the CO river bank. I believe you might even be able to get wet.
For return we can head back up via Shafer trial switchbacks, the over and down Long Canyon where everyone can get a photo of their Hummer under a giant boulder.
All are moderate so a good for a first timer to the Moab area. Nothing should get broken (including limbs).
