I did this hike 9/15/18. I workout at a gym regularly and consider myself to be in pretty good shape. I try to hike when I can but ultimately only get to a handful of times a year - so I would consider my skill level as a hiker, average. I stayed in Van Horn the night prior, woke up at 3:30am left at 4:30am and got to the trailhead/campground at 5:30am.The forecast for the day was 80 degrees F clear and sunny. I hit the trail starting at 5:45am, it was still dark and used my headlamp for the first 30-45min. Not even 5min in and I ran into a large deer off to the left of the trail about 10ft. The first 1/4-1/3 of the trail I would say is the most strenuous - lots of dry loose dirt and small rocks - although the top 1/4 is just as steep and unforgiving. As the sun started to come up there was still some patches of clouds. Hoping for clear skies and not worried about the overall weather, I pressed on trying to get to the top as quickly as possible. As I got about halfway the temperature dropped a bit, and the wind picked up, so I put a light fleece on. I kept moving uphill and only stopped to take a few pics, catch my breath and get a quick drink of water. The views are great all the way up, and they only get better. Getting closer to the top the scenery and landscape also continually change. I was probably about 3/4 of the way up and decided to change from my fleece to my wind/waterproof jacket. I also noticed the fog/clouds were lingering. I also hadn't seen anyone on the trail at all yet. Very peaceful and why I like to start early. As I was nearing the top(less than 5min from summit) I ran into 1 girl. She said she was also hoping for clear skies and good views but she hadn't seen them yet. I got to the top in 2hr 45min, only to have cloud coverage and gusty cold winds. I was still excited I made it to the top and was pumped standing on top of Texas! I waited for 45min hoping the fog/clouds would pass so I could see the epic view. Sadly I had an 8hr drive in front of me(plus the hike down) and couldn't wait all day so I got some pictures and videos, signed my name, re-fueled and proceeded to head down. I left the top about 9am and within 45min of coming down I had ran into about 8-10people. Towards the halfway mark I passed 2 large groups of kids, and the rest of the way, passed multiple more groups of 2-4people. I ended up at the bottom about 11:15am(total time 5hr30min). Overall I would say it is a strenuous hike, with very rewarding views and scenery all the way up and down. It's probably not as hard as some people say it is, but nonetheless come prepared and have good footwear. It does get hot early, so start early, bring plenty of water and snacks, sunscreen, sunglasses and a hat is recommended. Coming down is an absolute breeze so that is one thing to look forward to when going up.
