If you have the time, make sure to drive up Pike's Peak road to the top. Beautiful drive. Then the next day, take the Cog Railway from Mainitou Springs to the top of Pike's Peak. Relaxing, and you the driver, can actually enjoy some of the mountain scenery and take some pictures. Just remember, don't run to the refreshment stand, that 14K+ altitude will knock you on your A** until you get used to it.
Also, go south to the Royal Gorge. At one time it was the highest bridge in the world, not sure if that is still true. Another great scenic road is Old Stage Road. Just head toward the zoo on Cheyenne mountain, but at a junction take Gold Camp road, follow this through the canyon and you will eventually connect to Gold Camp road. Some old style tunnels. The entire area is just one giant future photo (outside and west of the city that is).
