Quinn Island sits just upstream of Cobram, formed by an old anabranch of the Murray. It's a small reserve of river red gum forest — perhaps half an hour's slow walk — and a good complement to the beach if you want shade and birdsong rather than sun.
A footbridge crosses from the Cobram side. The bird list is solid: laughing kookaburras, sulphur-crested cockatoos, white-faced herons on the riverbank. The reserve is dog-friendly on a leash.
