The Ayung River is Bali’s longest waterway, stretching 68.5 km's from the lush northern highlands down to the southern coast at Sanur. It snakes its way through deep gorges, remote jungles, rice terraces and traditional villages, making it one of the island’s most scenic natural features. Despite its size, the Ayung maintains a gentle flow for much of its length, making it ideal for outdoor activities like rafting and river trekking.
