The river arrives before the valley does — a narrow, bright ribbon that cuts through rice paddies and past low stone houses, daring you to keep up. You meet your guide under the palms in Senggigi before the road slashes inland; a short transfer, a quick safety briefing, and then the current takes over. Boats clatter, helmets click, and the first run of whitewater sends spray into laughing faces. Between rapids, the river slows and lets you look: terraces step down like green fingers, children wave from bamboo bridges, and the air smells of wet earth and frying tempeh.
