Swim Details


Welcome to one of the best kept secrets in the open water swimming community!  The Across the Lake Swim Rattlesnake Island consists of a more demanding 3.1km or 7km out-and-back swim that loops around the back of Rattlesnake Island.

Starting in 2014, the Rattlesnake Island swim was taken over by the Across The Lake Swim Society, which for many years has been running a highly successful and growing swim in Kelowna in mid July. The ATLS has grown the participation with enhanced safety features, improved swim support, more prizing, and an improved swag bag.

For those who have done the Rattlesnake Island Swim (RIS) before, there are lots of enhancements for the Swim. Otherwise, here is the blow by blow account of everything you need to know about the RIS, but were afraid to ask:

  • The process starts with the online sign up, which will be the ONLY way to register for the swim.
  • The 7KM participants MUST HAVE A PADDLER TO SUPPORT YOU - you will not be allowed to swim without one. If you cannot find a paddler, or your paddler fails to appear, you will NOT be able to swim. We cannot provide you with a support paddler or a support craft, but we can help you find one.
  • The 7KM out-and-back swim to and around Rattlesnake Island starts at approximately 7AM from the shores of Swim Bay in Peachland near the yacht club; the 3.1 KM swim begins at approximately 7:45AM, from Rattlesnake Island. 3.1 K swimmers will be transported to the island at approximately 6:45AM from the boat landing near the yacht club.
  • Support boats will support the swim with lifeguards along the route.
  • All swimmers will be required to use a Swim Buddy (supplied for you n/c), a safety device that you can learn more about here.
  • All registrants are encouraged to attend the free Fresh Air Open Water Swim training clinics put on by the Interior Savings Across the Lake Swim Kelowna for 5 consecutive Saturdays, starting in early June at the Boyce-Gyro Beach Swim Loop in Kelowna.
  • Race packages will be available for pickup the morning of the swim on Saturday, August 3rd, 2024, between 6-6:45AM, at the start area at Swim Bay.
