This trail was great and easy. The Tunnels were interesting and the view of Lake Mead along part of it was nice. I will say were walked it in Aug and it was 100 degrees. Although it wasn’t really too bad going. The only shade is the tunnels themselves which are only about 100 feet or so long. After the first couple its pretty much the same so you really don’t need to walk the whole thing, although we did walk all the way to Hoover Dam and back. IF you only walk part of it up until the 2nd or 3rd tunnel it would only be about 3 miles round trip. Just a little up hill in the beginning but nothing strenuous. If you go all the way to Hoover Dam there are a few more strenuous areas coming back. Don’t count on an Uber or Lyft at HD. It was our intention to take one back to the car. None responded to us so after 1/2 hour cool off we hiked back. Bring water where ever you go. Use Sunscreen too. Spring Mountain Ranch State Park over in Red Rock has some great areas as well. We took a moonlight hike let by guide there. It was great. Look on the State Park link itself for info. Red Rock area itself has some great areas to hike. Check out Mount Charleston as well. It’s a nice drive with some stop offs as well. Pretty areas when you get out of LV city area itself. The Valley of Fire is awesome and lots of places that all ages can enjoy. It’s just north of LV about an hour. None of the hikes/walks are overly long. Most are easy to moderate. I’m 58 and had no issues with any of the things I’ve suggestion. My son and GF went to Valley of Fire this past year and LOVED it. They are 28. Cool Petroglyphs, along with the beautiful red waves, some walks are on sand. Lots of areas the kids can climb up on if they choose, especially for photos. Big rocks and stuff. Get a map when you enter. It will give you info on all stopping point and info about each. I think it was $10 to enter at the gate and get the free map there. It has some beautiful scenery and its a great day out. If you can Look back in my reviews you can see photos and probably more info. The things I mention we did in Aug. of 2018. Reviews not organized like they used to be since TA updated their site. Have a great trip. IF you’ve never been to the Grand Canyon the drive there isn’t bad. A few hours. Hoover Dam is great along with a boat ride down the Colorado. We’ve done those too in the past. I’m not the biggest fan of the casinos, so every time we’ve been there we see things outside of LV when there for a show.

I agree with TravelinLady- the weather is unpredictable that time of year so be prepared for a variety of conditions. We walked most of the trail and it is not very difficult or strenuous so you should be able to make good time, but you will want to take photos.
