Pebble Beach is a recreation site on the east shore of Kootenay Lake, situated in a small protected bay roughly 5–7 km north of Riondel.

The beach is accessible by boat or via a moderately steep trail off the Kootenay Lake East Forest Service Road, where a signed trailhead provides parking; the hike down takes approximately 40 minutes.

The site is popular for sunbathing, swimming, fishing, picnicking, and camping, with room for several groups. The pebble beach is framed by exposed rock, offering pockets of seclusion, and at low water the shoreline opens up for further beachcombing.

A picnic table and pit toilets are available on site.
