Dharmadom Island is an uninhabited island covered with coconut palms and dense bushes sits beyond the confluence of Anjarakandy and Thalassery rivers. It is just 100 metres from the sandy beach of Dharmadom, which is set off from the mainland by rivers that surround it on three sides and the sea on its western side. You can wade to the island at low tide.. Dharmadam, known earlier as Dharmapattanam, was a Buddhist stronghold.
