Prospectors flocked to Black Hawk's gold mines back in the 1860s. These days, gamblers pursue Lady Luck at the town's 18 casinos. With Denver just 35 miles east, Black Hawk is a convenient destination for a weekend getaway. It's easy to get around town, too: A free tramway links the casinos. And, while gaming is the big draw, Black Hawk also offers a wealth of historical buildings.
