My wonderful wife has agreed to go on a backpacking trip in March (we would go together more often, but arranging for babysitting kids is tricky). We have family in St. George (southwest Utah) who can help us out during spring break (mid-March).

I've been given a few parameters and I'm in need of help to find a good match.

* Warm(ish) weather (tricky in March)
* Little elevation gain
* Three-day backpacking trip
* Southwest Utah
* Trees (for hammocks!)
* Low crowds (if possible)

I'm shying away from Zions because of possible crowds, but that is a possibility, especially for little-known trails.

I found one hike that I've done portions of -- the Red Mountain Traverse over Snow Canyon.

Please help if you can!
