Hi there. Two east coasters need some advice on driving from Denver to Las Vegas. We will be leaving Denver in the AM...driving and exploring all that day, spend the night on the road somewhere...and then arriving in Vegas the next day. On the map it looks like 70 West to 15 South is the most direct route. We're looking for a scenic route...possibly one that takes us through the Grand Canyon. Any suggestions for a route for us, including stops, considering our timeframe? THANKS IN ADVANCE!!
