off road driving
We hiked this at the end of the season (mid-May) so had to deal with temp in the low 90's. Long sections of the "trail" in the wash are hard to follow and with the zero shade, made for some cranky hikers. Thankfully there is plenty of shade in a lot of sections of the hike. Some scrambling and having to hack through foliage that had taken over the trail. Great shady spot to stop and have lunch near the trial end. As always, make sure to bring enough water. Those open sections were brutal, especially towards the end of the day.
4 wheel drive only. Marble Canyon well worth the drive.
