Crossword clue: Place with a breath-taking view?

The answer "GYM" fits the clue because it can refer to a "gymnasium," which often has large windows or is located in a high place, offering great views. Additionally, people often go to the gym to improve their health and fitness, which can lead to a feeling of being on top of the world. The play on words suggests that a gym can provide a "breathtaking" experience, both physically and visually.
