Biyyam Kayal or Biyyam Lake is a chief attraction in Ponnani and draws hundreds of travelers every year. It is a green fringed waterway situated in proximity to Ponnani town. What attracts visitors to this lake is the boat race held here annually during Onam season. Visitors can watch this race from pavilions built for spectators. Approximately two dozen country boats participate in the race which truly is a delightful sight.
Water sports facilities and other entertainment activities are available in Biyyam Kayal to engage the travelers. A boat race is conducted here on the third day of Onam celebrations every year, which is also a prime attraction of the lake.
Visitors can also get a glimpse of the beautiful hanging bridge built across Biyyam Kayal. Comfortable accommodation is available for tourists as there is a rest house equipped with all modern amenities on the banks of the lake. District Tourism Promotion Council (DTPC) has set up water sports facilities as part of developing this lake into a major tourist center.
