Dhani Nallah Mangrove is a one-kilometer long wooden boardwalk that twists through the mangrove creeks. This walkway is the longest one of its kind in India. It is perfect to observe the diverse mangrove eco-system in one place. The walkway opens up to the pristine long beach- Dhani Nallah Beach, which is popular as a hatchery ground for sea turtles. There is a small eco-hut, which is named as Olive Ridley, named after the most frequent turtle species of the beach. It offers a fantastic picnic area in the shadows of special casuarina trees with benches and sunbeds. You can enjoy at the swings and a bamboo tower from where you can praise the pleasant view of the whole beach.
