Phoenix Rock Gym is by far my favorite place to go indoor climbing. Whether you are a beginner or highly experienced you will find the perfect route for you. I really enjoy how the staff wonders through the gym helping you improve your skills and making sure you are using the equipment properly. The only negative for me is that it is so busy. Sometimes you do have to wait for a turn on for the routes. Then again, I have met some very nice people while I have waited.
