49 miles (Roundtrip) or 25 miles (one way). A FUN cruise that takes you past the famous Death Valley Sand Dunes, there is a restroom at the sand dunes but no water until you get to the Stovepipe Wells where we turn around. There is a store and restaurant there. The 24.5 mi. out to turn around climbs 662' and descends 470' with a max. grade of 4.3%. For 25 miles we need people driving out with their bikes and riding back, then people that rode their bike out would drive the vehicle back.
