The Bizant River is a tidal estuary flowing into Princess Charlotte Bay within the Rinyirru (Lakefield) National Park in Cook Shire, Australia. It is part of the broader Normanby Basin estuarine system. The river's primary access point for paddlers is the designated Bizant River camping area, which serves as a launch and take-out site for kayaks. This remote location offers a wilderness paddling experience within a national park setting. The estuary is subject to significant tidal influences, and paddlers must plan trips carefully around the tide stages, as the current can be strong. The area is known for a population of estuarine crocodiles, which are a major safety consideration requiring constant vigilance and adherence to local safety guidelines. Water quality monitoring is conducted near the river mouth, indicating the area's ecological significance. The landscape consists of coastal plains, and the river provides access to explore the natural riches of Princess Charlotte Bay. Camping facilities are basic, aligning with the remote and natural character of the park. Paddling here is suited for experienced individuals prepared for remote travel, wildlife encounters, and dynamic tidal conditions.
