Ob Luang National Park is an amazing attraction comprising both splendid natural charms as well as mysterious scenery. Under a bridge connecting the two sides of the narrow, steep gorge, a zigzagging river flows, framed by teak forests and mountains. During the rainy season, the flowing rapids crashing on the boulders and through the ravine are a dramatic picture of nature's strength. Subject to erosion by the strong currents of the river, the rocks and cliffs form the canyon and strangely shaped rock formations. The water has to force its way over rocks and boulders that obstruct the course making a magnificent sight.
