The Park O Winter Orienteering Series event on Thursday, 31 August 2017 is part of an annual series in and around Cairns running over several consecutive Thursday nights in winter.
Park Orienteering or Park O is conducted primarily in suburban parks, gardens, schools and crown land as well as via streets and lanes. A mass start or "scatter" style event is most popular, ensuring all competitors have one hour to locate as many of the 25 checkpoints from the provided colour map and clue sheet as possible. Checkpoints have varying values from 5 to 25 points depending on distance and navigation challenge. The person or team with the highest score is the event winner.
