The Southern Rockhole is a seasonal waterfall, located towards the top of the first gorge. This Rockhole is 4km (each way) by foot, or alternatively you can catch a boat ferry! Boat ferries are available either one-way (with the option of walking one way), or return. The boat ferry will take you within 150m of the Rockhole, you are then required to walk the remainder of the way. The walk is not a manmade path, and is rock-hopping the majority of the way in. As such, a moderate level of fitness and mobility is required. Swimming is only permitted when the Rockhole has been opened by Parks and Wildlife.
UPDATE: Southern Rockhole open for swimming on 20 November 2017. We recommend you to watch this space and conctact our Reservations team to make sure you are aware of potential seasonal closures.
