Across the Lake Swim Rattlesnake Island

Okanagan Lake presents a vast, expansive surface that demands respect from every athlete. As you push off from the shoreline at Swim Bay, the water typically greets you with a calm, glassy temperament in the early morning, before the thermal winds begin to stir later in the day. The sheer scale of the basin, stretching five kilometres wide near Peachland, means that conditions can shift; while you are unlikely to encounter significant currents, the open-water environment requires consistent sighting to maintain a straight line toward your markers. The lake's depth and geological history are visible even as you swim, with steep mountainsides and ancient terraces defining the horizon, constant reminders of the glacial forces that carved this landscape.

A landscape of folklore and fire

Navigating these waters brings you face-to-face with local legend and recent history. You are swimming toward Rattlesnake Island, often called 'Monster Island' by residents who maintain that the mythical lake creature dwells within a submerged cave beneath its rocky shores. The area is also marked by the 2003 Okanagan Mountain Park Fire; the scars of that massive blaze remain visible on the surrounding slopes, providing a stark contrast to the verdant Douglas fir and ponderosa pine forests that have since begun their slow recovery. As you glide, keep an eye out for western painted turtles near the shallows, while the rugged wilderness of the provincial park dominates the eastern view, accessible only by foot or boat.

Race logistics and history

The event offers distances of 1.5km, 4km, and 7.1km, each designed to showcase different segments of this historic venue. For the 7km participants, a dedicated support paddler is a mandatory requirement, a measure implemented to manage safety across the longer, exposed stretches of the lake. If you find yourself seeking shorter distances or a different pace, consider the local circuit, where events like Across the Lake Swim Gellatly Bay offer a similar challenge only a few weeks apart. The history of Rattlesnake Island itself is bizarre: in the 1970s, a failed development scheme nearly transformed this serene spot into a tourist park featuring a giant camel and a replica of the Great Pyramid of Giza. Today, however, the only thing you will encounter is the expanse of the lake, provided you arrive ready for the 7:00 AM start, with your timing chip secured on your ankle and your mandatory swim buddy inflated for visibility.
