One of our favorite places! Only about 2 hours away from Castle Rock, Breckenridge is a really cute ski town! Even without skiing, they have great restaurants & shops, snow activities, gondola rides, and is just fun to walk around in and take in all the pretty views. Highly recommend making a little vacation out of the trip if you have the time! Feel free to reach out to us for any recommendations :)
Another great town to visit. Rocky Mountain National Park is located here. While most of it is closed in the winter, it is still a pretty cool area to visit if you have an extra day or two.
