sẁiẁs Provincial Park occupies a beautiful natural spit of land on Osoyoos Lake. The traditional Okanagan place name for the area means 'where it is shallow or narrow in the middle of the lake' and is pronounced similar to "s-wee-yous."

There are 41 vehicle accessible campsites in sẁiẁs Park, all of them reservable four months in advance during the main camping season.

The campsites are arranged on a driving loop at the very end of the spit, with the majority of spots being directly on the lake. The 'inner' sites do have the benefit of more privacy, however. There are scattered trees (mostly Ponderosa pine and cottonwood) offering shade.
