While we were in Colorado, my mom and I took the kids up to Lookout Mountain to go hiking. Elijah hadn't been to the mountains since he was a year old, and last time he went hiking he was still in the carrier. Molly had never been to the mountains. (Last summer I kept waiting for them to adjust to the time change and sleep better, thinking the altitude would be extra hard on them when they were already exhausted, but they never slept well while we were there and so it just didn't happen.) I was really excited to take them this year!
Lookout Mountain is right off of I-70, so it's a quick trip (and a very convenient stopping place on our way to the Western Slope), and the Nature Center has easy trails for the kids. It was a great place for the kids' first hike! We all had a lot of fun. Molly kept saying, "We're in the mountains!" Elijah wanted to run the whole way. We saw some black squirrels and some birds, but not the Steller's Jay that Elijah was hoping to see.
There's a little museum inside with exhibits about the animals in Colorado high country - here's a mountain lion.
