Paravur Lake in Kollam district, Kerala, offers a unique experience of paddling through two ecosystems. The Ithikkara River flows into a brackish lake before meeting the Arabian Sea, creating a rich intertidal habitat. Kayaking through narrow mangrove channels allows visitors to observe mollusks, crabs, kingfishers, and egrets. Highlights include stops at Black Devil Snail Sandbank Island and Chithan Thampuran Temple Island. The best time to visit is October to March.
