The Sangre de Christo range is fairly rugged and dry. There are lakes in the valleys and bowls but streams up higher will be very intermittent. Getting up and down into the bowls or valleys will probably require some scrambling.
If you fish South Colony Lakes would be great, also day hikes up the peaks that are in the area. There are 5 Fourteeners that could be done as day hikes, Humboldt is class 2 but the rest are class 3.
The only thing I have done in the area is climb Crestone Peak, Needle, and Humboldt. I slept at the South Colony Lakes, beautiful area.

I did not take as many pictures as I wanted to, this was typical weather for the few days I was there, looking up the 3rd class route.
