This is one of the best trails in Las Vegas by far that i've been on.
The entire way is paved for you with proximity lights that get brighter as you run towards it and it helps you to see people from a far that are running towards you as well. I enjoy night running and so far i've had no run ins with any predators (knock on wood) but i'd make sure you'd bring a friend just in case.
You can park your car at the park on pebble and eastern by the colonade 14 and use the assisted cross guard to notify cars that you will be crossing. This trail ends at arroyo grande marking about 4 miles one way.
Great foliage accompanies you as you run through this otherwise desolate city, providing better air and wildlife to join you as you run.
There is one water fountain 0.5 miles into the trail from the pebble side, legacy park, and the park at arroyo has water fountains too.
This trail is great but if you want somewhere relatively more open and safer to jog at night in, the trail on st.rose is good too
