Protecting a small area of geological significance on the north shore of Kamloops Lake, the interesting feature giving the park its name can be seen both on site and from viewpoints across Kamloops Lake. The distinctive multi-coloured rocks and soils on an intrusion of batholithic rocks provide a muted rainbow of colour.

Note that no camping or day-use facilities are provided.
