Morning light filters through towering bamboo as the Ayung River threads past carved rock and stepped rice terraces, daring you into motion. Start with a heart-rate-raising 7-mile (12 km) white-water run—rapids generally sit in the Class II–III range—where guides read currents and the river pushes you toward each eddy and drop. After a buffet lunch at a local restaurant, saddle up for a 6-mile (10 km) ATV ride through Ubud’s jungle tracks, riverbanks and small waterfall approaches; the terrain flips between packed dirt, mud ruts and shaded single-track.
