Fernhook Falls Campground sits beside the Deep River in Mount Frankland South National Park, roughly 35 kilometres northwest of Walpole in Western Australia.

The surrounding landscape is dominated by karri, jarrah, and tingle forest, and the Deep River — one of the few south-west rivers with an almost entirely forested catchment — runs clear despite its tannin-dark colour.

The falls themselves are most dramatic in winter, when heavy flows roar over granite rocks into Rowell's Pool below.

The campground offers around eight tent sites that can also accommodate small campervans and camper trailers, plus two huts fitted with wooden slat beds and a wood heater.

Shared facilities include a covered camp kitchen with gas barbecues, picnic tables, and toilets. Caravans and large campervans are not permitted.

The site operates on a first-come, first-served basis with no advance bookings, and campers are asked to limit hut stays to three nights. Short walking tracks from camp lead to the falls and pool, and the river is suitable for canoeing and kayaking.
