My sister used to have a house next to Rocky Mountain National Park. I loved to visit. We never did any real hiking, but I liked walking the trails near the visitors centers on the main road. I did notice the thinner air up there -- I would have to go slowly and sometimes stop to rest and catch my breath.

Closer to home, I once tried a scrambling trail at Great Falls Park in Maryland and had to turn back after a while. I just didn't feel confident that I would not hurt myself, even with good knees.
