Explore Golden.
Only a stone's throw west of Denver, this outdoorsy western-style town offers alot of action. Nestled along Clear Creek, downtown Golden beckons kayakers and cowboys alike. Golden is also home to the Coors Brewery which offers daily tours and FREE BEER the last time I checked (following the tour).
Here are some other attractions to explore:
Golden History Museum
Bridgewater Grill
Colorado Railroad Museum
White Ranch Park
