Deep Time Walk - Port Melbourne - National Sustainability Festival

Join us for a Deep Time Walk as part of the National Sustainability Festival 2025 – A time travel through the rich geological and evolutionary history of the Earth up until the present day.

During the 4.6km walk, we will travel up the 4.6 billion years of the Earth’s history, at the rate of 1 million years per meter. We will journey through the Earth’s rich and complex history, stopping off at key moments to learn about the evolution of the planet and life on Earth through stories, conversation and reflection.

Starting at the formation of the solar system and the creation of the planet, we will cover some of the significant events which have led to life as we know it today: the formation of the Moon, the oceans, the atmosphere, the appearance of life, mass extinctions, and the arrival of our own species, humans.

A Deep Time Walk is storytelling through walking, it is a learning journey through our body, mind and soul, and a beautiful way to tell the story of life. Part history lesson, part mindfulness session this walk is all about stepping out of our lives and seeing the biggest picture.

In the course of this immersive, interdisciplinary experience you will:

• Grasp the real meaning of 4,600,000,000 years, the age of our home, and put its history into perspective
• Learn about the Gaia hypothesis of a self-regulating planet
• Fall in love with our beautiful planet all over again
• Explore the destructive impact our species is having on the living world

Please note the walk will begin and end at the same location, in Port Melbourne.

This event is co-hosted by the Port Phillip EcoCentre and The Biggest Picture.

About the facilitator

Tammy has a background in health psychology and believes that a strong emotional connection with the natural world is good for personal well-being, while also promoting climate awareness and action.

Tammy experienced a Deep Time Walk in 2014, and quickly saw their value in encouraging deep ecological awareness and an understanding of our planet as a precious environment from which all life has emerged. Tammy hopes the walks will renew individuals’ emotional connection with Earth, and motivate them to advocate for its protection.

Tammy’s website explains more about the walks she facilitates. For more information about the Deep Time Walk project, visit www.deeptimewalk.org.

“The walk itself really does affect the comprehension much more profoundly than reading it from a book. There was a tinge of sadness for me I have to admit, at the end, when we were talking about how briefly homo sapiens have been around, and we’ve destroyed so much in no time. It was humbling and sad at the same time. I really hope this time walk will spread and more and more people participate and gain something enriching for themselves.” Jackie
