If you come to Colorado, Rocky Mountain is definitely the place you don't wanna miss. Wildlife, hiking, camping, this is the scenic trip everyone enjoys. Take a deep breath of the mountain air when you hike up and feel like you're on top of the world!
Concerts at Red Rocks can be quite an experience if you have a free evening during your stay in Colorado. Please plan to arrive early to avoid traffic, study parking before you go, be prepared for the hike up and the cool night temperature. But if you don't plan to go to the concerts, Red Rocks looks magnificent in sunlight too! Sunscreen up and take a hike!
Pikes Peak is for sure an adventure to take. The mountain drive is totally worth it when you see the view along the road. And as you are in the area, you may consider Garden of Gods and other attractions in Colorado Springs, check the website: https://www.visitcos.com/things-to-do/attractions/
