Yes, due to the nature of Class III rapids, these trips have specific safety requirements, participants need to be in good physical health. While the exact minimum age can vary based on the specific trip and seasonal water levels, these intermediate trips typically require participants to be older than those on our Mild (Class I/II) trips. For all specific requirements, please check the Aspen Whitewater FAQ page or the details page for your chosen river section (e.g., Browns Canyon, Shoshone, or Upper Roaring Fork).
