Spotted Lake, located in British Columbia’s Okanagan Valley near the town of Osoyoos, is a striking natural wonder unlike any other. Its uniqueness lies in the distinct round formations that appear on its surface during the summer, creating an almost otherworldly landscape. This saline endorheic alkali lake, rich in minerals such as magnesium sulfate, calcium, and sodium sulphates, transforms each year as the summer sun evaporates much of its water, leaving behind clusters of brightly colored mineral deposits. These form the lake’s signature “spots,” which can range from white and yellow to green and blue, depending on the specific mineral content in each area.
Historically, Spotted Lake holds deep significance for the Syilx/Okanagan First Nations, who have revered the lake for centuries. The Indigenous people believe the lake possesses healing properties due to the high mineral concentrations in its waters. For them, the lake is more than just a natural curiosity; it is a sacred site used for medicinal purposes, and the various minerals were believed to treat a range of ailments. In recognition of this cultural importance, Spotted Lake has been granted protection and remains part of the Indigenous land rights.

In the 20th century, the lake’s minerals were harvested for their use in ammunition production during World War I, a shift from its sacred origins to a more commercial use. Later, efforts were made to preserve the lake’s natural state, and in recent years, there has been greater awareness of its ecological and cultural importance. In 2001, the land surrounding Spotted Lake was returned to the Okanagan Nation Alliance, allowing for continued stewardship by the Indigenous community.
Getting to Spotted Lake is relatively easy if you’re in the Okanagan region. The lake is located about 10 kilometers west of Osoyoos, just off Highway 3, making it accessible by car. Visitors driving through the area can pull over at a designated viewing area along the highway. However, because the lake is culturally significant and its preservation is a priority, visitors are not permitted to walk directly on the lakebed or its surrounding area. Instead, visitors can view the lake from a distance, taking in its unusual formations and learning about its history through informational plaques.
The visitor experience at Spotted Lake is a contemplative one. There are no commercialized tourist attractions nearby—no gift shops or cafes—only the opportunity to appreciate the lake’s quiet beauty and reflect on its cultural and natural importance. The best time to visit is during the summer months when the water levels drop, revealing the distinctive spots in their full glory. On a hot day, the contrast between the dry patches of lakebed and the spots is particularly vivid.
