Walk a 4.6 km path where every metre equals a million years, pacing through 4.6 billion years of Earth’s history. The route follows natural trails, alternating walking, reflective silence, scientific storytelling and sensory exercises that connect body and deep time. Expect shifting terrain underfoot and a contemplative, communal rhythm that reframes our place in the living world. Accessible to participants aged 15+, the experience blends physical movement with moments of wonder and shared reflection.
