Pichavaram mangrove forest is located between two prominent estuaries, the Vellar estuary in the north and Coleroon estuary in the south. The Vellar – Coleroon estuarine complex forms the Killai backwater and Pichavaram mangroves. The backwaters, interconnected by the Vellar and Coleroon river systems, offer abundant scope for water sports such as rowing, kayaking and canoeing. The Pichavaram forest not only offers waterscape and backwater cruises, but also another very rare sight – the mangrove forest trees are permanently rooted in a few feet of water.
