Good hike. A bit strenuous, but worth it…read more
But, if I had to choose between the South Rim, and Emory Peak, I would go for the South Rim. It's longer, not quite as strenuous, and more scenically diverse. Seeing the Rio Grand, from the South Rim, was amazing, but this is the Emory Peak page. If the South Rim had it's own Yelp page, I would go 5 stars!
Once you get to the top, you are rewarded with a pretty good view, and cell phone coverage. At least we had it on two different networks. So get that selfies stick out, and watch your step.
If you are aggressive, fast, and start early, you could probably do Emory and South Rim in the same day. Heading to the South Rim takes you to the path for Emory Peak, but it will add several hours.
We did not start terribly early, so we just did a quick out and back, from the Chisos Basin Campground ( https://www.yelp.com/biz/chisos-basin-campground-big-bend-national-park ), which is where we were camping.
Bottom line: If your pressed for time, I would skip it. Since we did South Rim, I would rather have seen more of the park, but hiking to the tallest spot in the park was pretty cool!
PS. Review is a bit late. We were in early March, 2018.
