Sẁiẁs Provincial Park, Provincial park on Osoyoos Lake in British Columbia, Canada

Sẁiẁs Provincial Park is a 38-hectare park occupying a narrow peninsula that juts into Osoyoos Lake in British Columbia. The site offers 41 campsites positioned along the shoreline with natural settings for outdoor recreation.

The park was established in 1939 as Osoyoos Park and renamed in 1962 to honor John Carmichael Haynes, a 19th-century magistrate. The 2015 renaming to Sẁiẁs reflected a shift toward acknowledging indigenous language and heritage.

The name Sẁiẁs comes from the Okanagan language and refers to a narrowing point in the lake's waters. This choice reflects the park's connection to indigenous heritage and local tradition.

The park is open each year from April to October and is managed by the Osoyoos Indian Band. Its 41 campsites sit on gravel pads along the lakeshore, separated by natural foliage. A paved road runs through the park, with cycling and hiking trails, one boat launch, picnic tables, tap drinking water and public toilets; a wetland area has self-guided paths and interpretive stands.

Archaeological digs within the park uncovered ancient remains estimated to be around 1200 years old, which were carefully reburied to honor their historical importance. This respect for the area's earliest inhabitants is reflected in how the park's identity evolved.
