Learn more about PaRx.

PaRx is an initiative of the BC Parks Foundation, driven by health-care professionals who want to improve their patients’ health by connecting them to nature. Featuring practical resources like quick tips and patient handouts, its goal is to make prescribing time in nature simple, fun and effective.

Each prescriber who registers with PaRx will receive a nature prescription file customized with a unique provider code, and instructions for how to prescribe and log nature prescriptions.

Parks Prescriptions began as a grassroots movement in the United States over a decade ago, and have now spread to countries around the world. We are proud to be Canada’s first national, evidence-based nature prescription program.
