40 Mile Beach, also known as Gnoorea Point, is a coastal camping and recreation area located approximately 56 kilometers south of Karratha in Western Australia's Pilbara region. The primary access for paddlers is via a natural boat ramp at the beach, which is one of only two viable boat launch points between Dampier and Onslow and is accessible by standard two-wheel-drive vehicles. The area is a natural, undeveloped coastal site with no drinking water available; facilities are limited to public toilets for day users and sullage disposal points. The overall character is one of a remote, wilderness coastline that offers a sense of quiet and space in a region otherwise dominated by industry, serving as a popular camping destination for families and recreational users.

The beach provides protection for those in the water, suggesting generally tranquil conditions within the bay, though paddlers should be mindful of exposure to open ocean winds and weather. The coastline features numerous separate campsites spread along the shore. A significant consideration for trip planning is the presence of a proposed large-scale solar salt farm development, which, if approved, could alter the landscape and experience of the area through the construction of evaporation ponds and infrastructure. The area is valued for its social and cultural significance to the local community. For wildlife, turtles are often sighted in nearby Cleaverville, indicating potential for marine life observations along this coast. Camping is permitted with a paid booking required during the peak season from May 1 to September 30, with a maximum stay of 28 days; no fee applies from October to April but a three-night limit per 28 days is enforced. Dogs are permitted at the campgrounds under controlled conditions, such as on a leash.
