This is one of our favorite walking trails. It is about 8 miles round trip starting from Lake Mead parking lot. It is basically flat until you get close to Hoover Dam. We always refill our water and eat lunch at Hoover Dam Cafe before walking back. The views of Lake Mead are beautiful and I believe they filmed the scene where Clint Eastwood and Sandra Locke are on a motorcycle going through the tunnels while being chased in the movie The Gauntlet!
Please note: this is a great walking trail but most of the Yelp reviewers say this trail is very easy but please don't make to light of it unless you are use to walking several miles because it can get hot and windy and there is really no shade. Make sure you bring lots of water and PLEASE leave your dog home if he/she is not used to walking several miles either because I have seen some dogs in distress. THEY NEED WATER TOO and the rocky trail can cut up their paws.
