Viti Levu, particularly the grasslands between Ba and Rakiraki, is crisscrossed with ancient pathways known as tualeita. Dating back centuries before European contact, most of the paths run along the highest ridges allowing walkers to spot enemy war parties and to avoid being followed. The paths played an important role in the Fijian colonization of Viti Levu, linking pioneer settlements to the main chiefly villages. Before the widespread conversion to Christianity, tualeita also held a religious importance. It was believed that the spirits of the dead followed the trails on their journey back to their origins, and thence on to the afterlife. Most walking tracks today follow tualeita.
