Tucked away in the Upper Wairau River area inland from Nelson, Coldwater Stream Campsite is a remote spot that works well as a base camp for 4WD trips or as an overnight stop while exploring the region. The setting is quiet and rugged, with the river close at hand for fishing trout or launching a kayak. Facilities are basic: non-powered tent sites, non-flush toilets, and water drawn from the stream, so come self-sufficient. The ground is gravelly, so pack sturdy tent pegs and be prepared to re-seat them if the wind gets up. It's more of a handy stopover than a destination in itself, but the river access and the sense of getting well off the beaten track make it a worthwhile pull-up for those heading deeper into the backcountry.
