Starting from pretty Alexandra, this is an extraordinary one-day adventure often combined with the Clutha Gold and Otago Central Rail Trails that connect at each end. The trail follows the mighty Clutha Mata-au River through the Roxburgh Gorge, a strange landscape of towering bluffs, old schist huts, interesting flora, and finishing at the Lake Roxburgh Hydro Dam.
