The Pelorus Bridge Scenic Reserve is about halfway between both Picton and Nelson, and Blenheim and Nelson, on State Highway 6. It's a good example of the native lowland forest—with beech, podocarp (a species of evergreen tree), and broadleaf trees—that once covered this whole region. There's a network of easy walking trails through the reserve, and in summer the river is warm enough for swimming (watch out for the sand flies after the sun goes down). There's also a rare colony of endangered long-tailed native bats that come to play round the streetlight at the bridge at night. It's an utterly delightful place to take a pause, especially with a campground and cafe just meters away.
