Deep Time Walk Barcelona - May 2026

Experience the entire 4.6 billion years of Earth in a single walk. ​Seeing humanity within the vast arc of planetary history can shift how we think about progress, civilization, and our relationship with the Earth. ​A Deep Time Walk is a slow, guided walk combining science, storytelling, and reflection in nature. Together we will walk 4.6 km through our planet's history, where every meter represents one million years. ​What to expect ​This may be for you if you are curious about climate and ecological change, systems thinking and long-term perspectives, or humanity’s place in the story of life - and would like to reconnect with nature in a thoughtful way. ​No prior knowledge needed - just curiosity and a willingness to spend a few hours exploring deep time in nature together. ​Your guide ​This private, non-commercial activity will be facilitated by Daniel Hires, a systems thinker and speaker working at the intersection of leadership, ecology, and systems change.
