Alexandria Bay is a beach located within Noosa National Park on Queensland's Sunshine Coast. Access is via walking trails, primarily the Alexandria Bay Walk, a 4.2-kilometer grade 4 hike from the park entrance. There is no direct vehicle access to the beach itself, and parking at the national park trailhead is limited, encouraging visitors to walk, cycle, or use public transport during peak periods. This means paddlers must carry their kayak, SUP, or surf ski a significant distance over a hiking trail to reach the water. The bay faces east and is noted for its exposure to ocean swells, with the area around the headland known for bigger surf breaks. The beach is characterized by white sand and warm water, and its relatively isolated location has historically led to its unofficial use as a clothing-optional beach, though public nudity remains illegal in Queensland. The surrounding Noosa National Park features a coastal track that passes by the bay, offering scenic views of giant granite rocks, caves, and marine life. The water body is part of a sparkling coastline, and the area is a known destination for surfing. Paddlers should be prepared for potential surf conditions and shore break when launching and landing, and must respect that the primary access is through a national park with limited facilities directly at the beach.
