Withnell Bay is a beach in the north-western area of Western Australia and is on the south-western edge of the Murujuga National Park.
The beach is about 300m of high tide sand with two sections of rock breaking it up and a rock ledge and mangroves bordering it.
Following the signs to Withnell Bay takes you to the entrance of Murujuga National Park. The track from here on is rougher and is meant for higher clearance off-road vehicles, walking, or mountain bikes.
Withnell Bay is named after Emma Withnell 
, a pioneer and first white female settler in north-west Western Australia. Emma and her husband John Withnell began operating Mount Welcome station, in which the homestead became the side of the first town in the area, Roebourne.
There is a lot of Aboriginal art on various rocks scattered around the trails in the Murujuga National Park, however, we didn’t venture beyond the beach. In contrast, the opening of Withnell Bay is lined on one side with the Karratha Gas Plant , where the North West Shelf Visitors Centre is.
