Cogburn Beach is a rustic recreation site stretching roughly 2 km along the eastern shore of Harrison Lake, offering direct access to the water from a road that runs just metres from the shoreline.

The site features a long pebble beach with west-facing views of the lake and surrounding mountains, making it a popular spot for swimming, boating, and fishing.

Camping is tent-only on the beach itself, where sites are informal with rock fire rings and no tables. A small number of forested tent sites with tables are also available, tucked into a treed area accessible via short foot trails.

Potable water and garbage receptacles are not provided, so visitors must pack in their own water and pack out all waste. Pit toilets are on site.
