Across the Lake Swim Gellatly Bay

Okanagan Lake is a remnant of glacial activity, a deep, 145-kilometer-long trench that holds its temperature with a stubborn thermal inertia. When you push off into the water at Gellatly Bay, you are entering a basin that feels less like a lake and more like a submerged canyon. The water here is dark, reflecting the surrounding slopes where the remains of a 60-million-year-old stratovolcano, Mount Boucherie, dominate the horizon. Erosion has ground this volcanic giant down from its original 2,000-meter peak to a modest 417-meter silhouette, yet its presence remains the primary orientation point for any swimmer tracing the shoreline.

A landscape of fire and vines

As you navigate the course, the shoreline serves as a record of human and geological struggle. You will pass the historic St Hubertus and Oak Bay vineyards, first planted in 1928, which stand as a stark contrast to the scars left by the 2003 Okanagan Mountain Park Fire. That summer, the blaze tore through the valley, reshaping the local landscape and destroying the original estate winery along with hundreds of homes. Looking toward the land, the territory belongs to the Westbank First Nation, whose connection to these shores spans thousands of years. The sight of the Mission Hill Family Estate, perched high on the opposite rise, provides a reference point that helps maintain a straight line through the bay.

Water and myth

Swimming in these waters often involves a glance toward the deeper channels, where the legend of Ogopogo persists. While the creature remains a local curiosity, the sightings reported from the heights of Lakeview Heights reflect the sheer scale and depth of the lake. For those preparing for this distance, the event offers 1500m, 2500m, and 5000m options on August 22, 2026. This gathering is part of a wider regional circuit; many who compete here also test their endurance at the Across the Lake Swim Kelowna held earlier in the season, or the challenging Across the Lake Swim Rattlesnake Island. The organization relies on local logistics to manage the traffic on this expansive body of water, ensuring a clear path for all participants as they finish their transit in the bay.
