About Trails Rx

Unleash the
Healing Power
of Nature

Trails Rx is a wellness program created by Dr. Suzanne Bartlett Hackenmiller in collaboration with the Sempervirens Fund. It leverages the physical and mental health benefits of spending time in nature by guiding users through designated trails at Santa Cruz Mountains.

The program encourages regular use of these trails to integrate nature's healing benefits into daily life.

Physical Health Benefits

Each trail is assessed for physical benefits, offering various levels of exertion and specific exercise recommendations.

Mental Health Benefits

Trails feature invitations to engage with mental health prescriptions, or forest therapy invitations, designed to help users relax, connect with their senses, and quiet their minds.

Parks prescriptions, or Parks Rx, is a movement based on the fundamental idea that spending time in nature is good for your health. In California’s Bay Area, most counties host a Parks Rx program, often connecting parks and public health departments. They provide resources for clinicians and doctors to recommend, like reminding a patient to exercise, spending time in nature as part of your health and wellness plan.
