We did this hike last year over Labor Day weekend. Yep, the first part of the trail through open desert is very easy.

We started off about 5:30pm, and the temps weren't too bad. Late afternoon is quite nice - the sun hits the west-facing Chisos and makes for some beautiful colors.
Getting through the wash, as stated before, wasn't easy. I ended up with a few cactus thorns in my shins and scraped my leg pretty good on a dead branch sticking up from the ground. Of course my injuries were mainly a result of trying to keep up with a 2 1/2 year old

Shortly before we reached the dikes, we ditched the wash and climbed up to our right. Although we had to scramble a bit, it was a little easier than wading through the grass, cactus, and bushes in the wash.
We stopped at the dikes and had a picnic dinner. The thick greenery behind my sister, wife, and son here is the wash. The terrain drops away steeply, although you can't really tell that from this photo. We could see water down in the wash through the trees.

The views headed back were really nice. I'd go back just to hike the open desert portion of the trail and watch the sunset. I didn't get a good shot looking south or west when we hiked back, unfortunately, but it was nice. The views east towards the Chisos were nice too.
On the hike back, we encountered a rattlesnake shortly after hiking out of the wash section of the trail. So we hauled butt back to the truck. I snapped this shot after everyone had calmed down.

Here's the east view not too long before sunset. You can see the dikes converging on the wash in this photo.
