Carbon Beach, also known as Billionaires Beach, is a mile-and-a-half-long crescent-shaped beach in eastern Malibu, California, extending from the Malibu Pier to Carbon Canyon Road. It is a south-facing, gradually sloping sandy beach, which is one of the widest in the area and retains a significant amount of dry sand even at higher tides compared to other local beaches. Public access for launching paddlecraft is limited to two specific accessways, both gated and marked. The western access, known as the Zonker Harris Access Way, is located at 22670 Pacific Coast Highway. The eastern access, often called the David Geffen Access, is at 22126 Pacific Coast Highway. Both involve a short walk from the highway down to the sand. On-street parking along Pacific Coast Highway is extremely limited and competitive; a common alternative is to park at the Malibu Pier lot, which charges a fee, and walk east along the beach at low tide to reach the water. There are no public restrooms or other facilities at the beach access points.

The beach's character is defined by its exposure to the open Pacific Ocean and a continuous line of private, lavish residences. This means paddlers should expect no solitude and should be mindful of private property boundaries landward of the high tide line. The beach slopes gradually, which typically results in a gentle shore break, but conditions are entirely dependent on Pacific swell and wind. The area is exposed to prevailing winds and ocean swells. Paddling north from Carbon Beach, past the Malibu Pier, leads to the Adamson House, a historic Spanish colonial revival estate noted for its architecture and tilework, making for a straightforward destination. The Malibu Pier itself is a nearby landmark. Water quality information is not detailed, but general ocean conditions apply. The beach is open to the public from sunrise to sunset, and dogs are not permitted.
