The Well is a nice place. It's usually quite busy on the weekends, but not so much during the week.
It has only one pool, but the pool is huge -- big enough for a hundred people. Suzanne and I used to go there often. It's only 40 minutes South of Colorado Springs.
The weekend crowd tends to be all ages -- from toddlers to great-grandparents. A lot of families. The weekday folks tend to be middle age men and women. The Well is a fun pool, but it does not have the same feel or atmosphere of, say, Valley View Hot Springs.
Valley View is much, much more natural, and a good number of people treat it as if it were a sacred place. As if going to it were a spiritual experience. No one treats The Well that way. It's more of a party pool than Valley View. There are several hot springs in Colorado. The ones that aren't free -- that is, undeveloped springs, usually on public lands -- tend to fall somewhere between The Well and Valley View in terms of atmosphere.
