Darwin's Walk starts from Wilson Park Wentworth Falls and runs across a boardwalk and bush track through open forest, shrub, and hanging swamps to the national park boundary. It was in the valley at the end of Jamison Creek that Charles Darwin stood in 1836, struggling for words to describe the 'quite novel' scene before him, the 'immense gulf' and the 'absolutely vertical' sandstone cliffs where 'a person standing on the edge and throwing down a stone, can see it strike the trees in the abyss below'.
