Lookout Mountain has many “lookout” spots that have some beautiful views. One is at the same site as the Buffalo Bill Museum and Grave, another a short drive (there’s also a walking path) from there and then tons of other hidden gems off the roadside.
Table Mountain is a nice hike right in Golden. Jen has done North Table Mountain and while the initial STEEP climb up is difficult, it’s all mostly flat once you’re up & has gorgeous views.
Estes Park is about a 1.5 hour drive from Golden, BUT the views on the drive are spectacular! There are multiple spots to pull off and get out and enjoy the mountain views on the drive. Estes Park itself has amazing views of the Rockies & is a good starting point if you’re heading to Rocky Mountain National Park.
