The Keystone Lake remains a highlight of Keystone. It is beautiful, Summer and Winter. In the Summer, there are paddleboats on the lake as well as lots of waterfowl. Trout are visible and respond quickly to food, which is available for purchase at nominal cost. Several restaurants have lakeside dining.
A word of caution. There is a lot of construction ongoing and a number of businesses are presently closed. Things should be back to normal by mid-Winter
