I am a beginner in climbing. The best I've done is the Grand Canyon a few times. Good luck on your trip. This foundation is critical to your success as a mountaineer. Invest your precious vacation in trips to more exotic climbing locations.
Winter climbing in New Hampshire is a great stepping stone.
