About this tour
Only got an hour? This is the shortest way to get from the river to the bay. You'll ride from Rivergate Marina under the Gateway Bridge, past the Port of Brisbane and out to St Helena Island — a colonial-era prison island that's now a national park, sitting at the edge of Moreton Bay Marine Park.
It's a mix of river cruising and open water, with wildlife spotting along the way. Moreton Bay can be choppy in the afternoon, so expect a few bumps and some spray. Want a longer, smoother ride? The Brisbane City Sunset Tour gives you twice the time on the water.
