Yahman Adventure Park is located at 405-hectare (1,000-acre) Prospect Plantation, bought by Sir Harold Mitchell in 1936 and still owned by his heirs. Mitchell entertained all manner of dignitaries in the great house and at the estate's luxurious villas. A tradition held that his guests would plant a tree on the grounds to mark their visit. The most notable of these tokens of remembrance is the giant mahogany planted by Winston Churchill in 1953. It stands in the driveway behind the great house.
