The Cliff to Bridge is a river marathon unlike any other. Spanning 15km along Tasmania’s mighty Derwent River, this swim is a true test of endurance, pacing, and mental strength, set in one of the most peaceful and picturesque swim settings you’ll ever experience.

Starting beneath the dramatic sandstone cliffs of New Norfolk, you’ll follow the river’s winding course through a landscape of misty valleys, native bushland, and farmland that seems to exhale calm. The Derwent’s tannin-rich, tea-coloured water is gentle and glassy, offering a steady current in some sections and quiet reflection in others.

You’ll be supported all the way by safety craft, paddle crews, and a passionate team of volunteers who understand what this swim means. The finish line at the New Bridge brings both relief and elation, and the chance to say you’ve completed one of Australia’s most unique marathon swims.

Whether you’re chasing a personal challenge or soaking up the meditative rhythm of a long swim through nature, Cliff to Bridge is a bucket list experience. It’s not just about reaching the end, it’s about the journey through Tasmania’s inland soul, one stroke at a time.
