Cascade Beach is a recreation site situated along the shores of Mabel Lake, a large lake located outside of Lumby in British Columbia's Okanagan Valley.

The site offers free campsites, making it a more rustic alternative to the developed facilities at Mabel Lake Provincial Park further up the lake.

Mabel Lake itself is the tenth largest lake in British Columbia and is well regarded for salmon fishing, swimming, kayaking, and paddle boarding, all of which can be enjoyed from this access point.
