Nice local family that gave us a tour in the mangrove area. Authentic experience, no repetitive performance here. Did some tracking and birdwatching. If it's more clear what things you can do and see, and during which season, I think this can be interesting for more people. We enjoyed a nice 3h, 4p private boat trip and a short walk in the mangroves before and during dusk/ sunset, at 25k including pickup from Nilaveli (5k). Bring binoculars for king fisher birds, several types of cranes, hawk, hornbill, crabs and jumping fish (July'24). Wear closed shoes and bring insect repellent and sunscreen. In other seasons, elephants, crocodiles and boars are to be seen, for example by going out camping in the jungle behind the mangroves. That sounds great if the price and the season is right.
