My husband and I walked this trail with our dogs on an early Saturday morning. The trail is paved and runs along the power lines waaaay out Southeast. You can walk/bike on this trail. I think it is made more for biking than walking. A lot of people were biking there the morning my husband and I were walking our dogs.
If you do the entire trail it is 30+ miles. The first 4-5 miles is kind of boring because you are simply walking a straight path. The only nice thing is you get really picturesque views of the entire Las Vegas Valley. Once you get about 4 miles in the trail veers to the right and I am assuming at some point you would be able to see Lake Las Vegas to your left if you kept going.
My husband and I turned around at the 4-mile mark and walked back. Our dogs were tired. So were we.
I would also suggest starting this trail at a different point to get a better hike out of it. I think next time my husband and I will try to start it from an area by Lake Mead. Perhaps my rating will go up then, we will see.
