If I recall correctly, it's about 1 hour to Hoover Dam (southeast). If I recall correctly, it's 45 minutes or so to Red Rocks (west), depending on what part of the city you're coming from. Hoover Dam ... do the tour. You won't regret it. And just for the record, even though I love Mrs. See's candies, don't bother going on the free tour. Red Rocks...you can drive the loop road, or get out and walk around. This place is beautiful. I might add that there is a September 11th memorial; around back of the visitor center. As a New Yorker, I was moved.
