A wild Hokkaido loop through the heart of Daisetsuzan National Park — Japan's largest. Route 39 follows the Ishikari River into the dramatic Sounkyo Gorge, where 200 m basalt columns flank the road on both sides. Route 273 then climbs over the Mikuni Pass (1,139 m) — Hokkaido's highest national highway — through untouched boreal forest before descending to Nukabira and looping back via the lavender plains of Furano.
