Based in Pacific Harbour, Rivers Fiji operates year-round, guiding guests through the Upper Navua Gorge—a deep chasm shrouded in lush rainforest and fed by numerous waterfalls. The rafting experience features Class II-III rapids, making it suitable for both novices and seasoned adventurers. In addition to rafting, they offer inflatable kayaking trips on the Middle Navua River, allowing for a more relaxed exploration of Fiji's interior, including visits to local villages and hikes to waterfalls.

Rivers Fiji is renowned for its commitment to sustainable tourism and conservation. In 2000, in collaboration with local landowners, villages, a logging company, and government entities, they established the Upper Navua Conservation Area (UNCA). This initiative protects a 17-kilometer stretch of the Upper Navua River and 200 meters on either side from logging and gravel extraction, preserving the river's pristine environment and providing economic benefits to the local communities through sustainable tourism.

The company's dedication to environmental stewardship and community engagement has earned them recognition as one of the best adventure companies in Fiji. Their experienced Fijian guides offer not only safe and exciting river adventures but also cultural insights, enriching the overall experience for guests. By choosing Rivers Fiji, adventurers contribute to the preservation of Fiji's natural beauty and support the livelihoods of its indigenous communities.
