My kids are all just happier if they are outside. It's hard to know what trails and natural areas will be most fun for them. I kept hearing about parenting groups who were doing outings at the "ELC". What's the ELC? It's CSU's Environmental Learning Center near Drake/Ziegler in Fort Collins. They offer all kinds of programs to teach our community about nature. My twin boys, and my friends twin boys, loved the place! It's a easy hike with great trails and mostly flat terrain.
