LEARN MOREListed escort pilots and their boats are neither commercially nor financially connected to the Derwent River Big Swim. Therefore, you must book a “swim window” with them. Payment is between you and the escort pilot.
It is not always possible to decide for yourself when one’s swim starts. Here you will have to trust the people in charge on the escort boat. As the Derwent River Big Swim offers many complicated weather and sea conditions, there are many factors to consider. This means the pilot keeps a close eye on these factors so that you have the greatest chance of success of your swim.
When you book your escort pilot, you will be assigned a specific day to swim. You can swim 2 days before or 2 days after the assigned day. This becomes your "swimming window".
Which day you swim in your window depends on weather and river conditions. Therefore, you must be patient, as the weather is the only thing that cannot be changed. Fortunately, this can also mean that you will be able to swim in the agreed window.
Start your journey on the Derwent River. Each swim is a personal test of endurance, strength, and connection to one of Australia’s most beautiful waterways.
