Osoyoos Lake

Osoyoos Lake is an international body of water stretching roughly 18 kilometers (11 miles) in length, divided between Canada and the United States at the 49th parallel. Two natural sand spits, including Haynes Point, create distinctive features that break up the lake's shape as it runs north and south.

The lake was carved out roughly 17,000 years ago when glaciers retreated and meltwater shaped the landscape of the Okanagan Valley. This glacial activity created the deep basin that holds water today.

The name comes from the Okanagan language and means "snake," reflecting how Indigenous peoples understood the water's shape and movement in this region. The lake remains tied to the communities who have lived here for countless generations.

The water becomes pleasantly warm in the hotter months, making swimming and water activities comfortable without cold shock. The best time to visit is between June and September, when water temperatures peak and recreational activities are most popular.

Haynes Point is a long, narrow sand spit that extends like a natural bridge across the water, completely changing how the lake feels from within. Walking across this sandy strip puts the water on both sides of you at once.
