If you live in Colorado, are visiting here or anywhere near, you have to go to Red Rocks Park and Amphitheatre (redrocksonline.com). Located near Morrison there is plenty to do in this area including hiking, biking, taking great photographs and there is of course the naturally formed amphitheatre which happens to be my favorite part. As spring and summer are upon us the concert season at Red Rocks is also beginning. Many artist have commented positively on this location saying it's either their ambition to play here or their favorite venue. Treat yourself to something wonderful and check it out!
When events aren't going on a lot of fitness minded folks will use these stairs as part of their work out (lungcolorado.org).
I love this image with the people walking around because it really shows the scale of these rocks!
