Coldwater Stream Campsite sits in the Upper Wairau River area of Nelson/Tasman, managed by the Department of Conservation. This remote site accommodates caravans and tents, with basic toilet facilities provided. Access is via Rainbow Road, a gravel toll road requiring high-clearance 4WD vehicles and crossing stream fords. The campsite serves as a base for four-wheel-driving, trout fishing and kayaking on the Wairau River. While camping is free, road access fees apply. The toll road typically operates from Boxing Day to Easter Monday, with restricted access at other times. Contact the operator for current road conditions and seasonal access details before planning your visit.
