A guided walk through Nature

(5h walk. 5-20 participants)

Deep TimeWalk

A 4.6 km walk to discover Earth’s 4.6 billion year history-1 metre is equivalent to 1 million years of the Earth’s history.

During the walk the participants, explore the Earth’s evolution, learns about the role and development of greenhouse gases on Earth, experience the appearance of bacteria, nucleated cells and, eventually, multicellular organisms, evolution of species, and the arrival of humans.

The journey starts from the point where the Earth begins, with zero oxygen and no liquid water. It goes through the birth of Gaia 2 700 million years ago. The ancient Greeks gave this name to the Earth, highlighting the Earth as a living being, the divinity of its creation after the chaos and ability of self-regulation to maintain the delicate balance between living-beings, rocks, water and the atmosphere.

The walk then raises a rhetorical question, whether science is enough for the understanding of the evolution of the Earth.


While the Deep Time Walk offers the scientific explanation based on the latest inter-disciplinary evidence, it also leaves room for spirituality, which correlates with Earth Charter Principle 14d on the integration of different types of knowledge and values into learning including moral and spiritual education for a sustainable lifestyle.

During the walk, the participants recognize that 252 million years ago the greatest extinction of species occurred with 96 % of marine and 70 % of terrestrial species gone. The Earth became quiet “like the Earth after us”. We can say this moment represents the preamble of the Earth Charter, with the critical moment in Earth’s history when humanity must choose its future.

The Deep Time Walk helps the participants feel their connection with the community of life and to recognize the role of mankind in the evolution and protection of our living Earth.
