Grainger Creek Campground is a backcountry campsite located within E. C. Manning Provincial Park, situated where the Grainger Creek Trail meets the Hope Pass Trail, approximately 6 kilometres along the route from the Skaist River corridor.

The campground accommodates up to three tents and is equipped with a pit toilet and a firepit. Grainger Creek runs directly through the site, providing a reliable water source year-round, though water should be treated before drinking.

The site also serves as a trailhead junction, making it a natural stopping point for hikers travelling the Heather Trail system or the historic Hope Pass Trail, a wide wagon route originally built in 1861–62.

The surrounding terrain follows the Skaist River through heavy timber, with water plentiful along the approach.
