This is an option for a day when the bay is blown out as you need good wind with enough power to penetrate inland. Wind direction is immaterial as the river meanders all over the flood plain with evidence of many past and developing Oxbow- lakes.
The river is definitely tidal upstream to the Caboolture Weir so ideally plan around the tide. The effect reduces the further you get from the coast If you choose to return down- river against an incoming tide when you are tired, limit your distance a bit and be prepared for some hard work.
The river provides you with 19 kilometers upstream to the Caboolture Weir to play on, passing through some lovely countryside, past moored boats, riverside houses in places and the boatyard.
Launching is a pleasure from the Beachmere side with a large carpark, a pontoon and two ramps with a small area of beach but the best thing is that it is notably under- utilised. There is a nice covered shelter and decent toilet block. There is also a similar area directly opposite with a good ramp which you would access from Uhlmann Road, Burpengary- also under- utilised.
