The lake was created in 1985 by the Kenyir Dam on the Kenyir River. The lake provides water to the Sultan Mahmud Power Station. It is the largest man-made lake in mainland South East Asia with an area of 260,000 hectares.

Vast in size, this great lake is surrounded by the world’s oldest rainforest, stretching as far west as Kelantan and south to Pahang, Kenyir serves as an alternative gateway to the famous Taman Negara (National Park).

Dotted with more than 340 islands throughout the lake, which were once mountaintops and highlands, Lake Kenyir is home to more than 14 cascading waterfalls, cooling waters, an abundance of rapids and rivers, and an idyllic sanctuary to numerous species of freshwater fish and exotic wildlife. Flora and fauna thrive in its vast landscape and are a treasure trove of discoveries and adventures for nature lovers.

Although an artificial lake, the area has been successfully developed for eco-tourism, and there are many resorts on its shores. Fishing is popular, as are jungle treks, waterfalls and caves. Popular spots for jungle trekking are Pengkalan Gawi, Bewah at National Park, along the rivers of Saok, Lasir, Tembat and Lawit. Kayaking, canoeing, boating, rafting and rapids shooting are among the many water sport activities available here.
