The Annan River is a coastal estuary flowing through the Annan River (Yuku Baja-Muliku) National Park, part of the Wet Tropics World Heritage Area near Cooktown. A single-lane concrete boat launch ramp provides the primary access point for paddlers, offering direct launching into the Annan River estuary. This ramp is suitable for small craft like tinnies and sportsboats, indicating it can also serve as a put-in for kayaks, canoes, and SUPs. The river meanders through lush landscapes featuring a blend of tropical rainforest and riverine vegetation, including kapok trees, figs, and ferns, creating a scenic backdrop. The area is rich in wildlife, with notable species including the cassowary, water dragon, and numerous bird species, offering paddlers opportunities for wildlife observation. The park emphasizes the cultural significance of the Yuku Baja-Muliku people, who have lived in the area for thousands of years. Public restrooms and a designated parking area are available near the park entrance. The river mouth area can experience significant wind gusts, with forecasts indicating gusts can reach over 10 meters per second, which can create challenging conditions and fetch on open water. Paddlers should be prepared for potential rain and light to moderate winds that require experience. The estuary environment suggests tidal influence is a key factor for paddlers to consider regarding currents and water levels. The gorge section of the Annan River is immediately beside the Mulligan Highway, though it is easy to miss from the road.
