A really neat place to poke around in central Colorado is Paint Mines Interpretive Park, just outside Calhan and about 40 miles northeast of Colorado Springs.I used Google maps to create a road trip there and was quite surprised at the amount of small farms I passed along the way. On the return trip home, I followed another plan which challenged my route finding skills plus offered more scenic views.
Small paths lead left and right into the Hoodoos and spire erosion areas. Beware as these rocks are soft stone and wear easily. I will caution you here to just follow the trails as far as you can into the rocky areas, keeping the sandy ground underfoot but beleive the signs and DO NOT CLIMB THE ROCKS! It is hard to tell just where to stop, but figure that any wear you create on the rocks means those rocks will never be seen as the same again by anyone else.
Covering 750 acres, the total trail mileage is around 4 miles if you follow all the way around. A Trail Map is HERE.
