Gunlom is an utterly superb escarpment waterfall and plunge pool 40-odd kilometres south of Maguk and 37km along an unsealed, though easily doable, gravel road. The reward is a gloriously large waterhole and drama-filled scenery, and that's just 200m through the paperbark forest from the car park. There's also a lovely picnic area here. If you're keen to explore more, take the steep Lookout Walk (one hour, 1km), which affords incredible views.
Birders should watch here for the white-throated grasswren and chestnut-quilled rock pigeon.
