Guidelines

Wear Life Jackets During the Boat Safari: Safety first – always wear a properly fitted life jacket, especially during the mangrove boat safari, which passes through narrow and deep water channels. Respect the Environment and Wildlife: Do not feed or touch animals, especially birds, monkeys, or reptiles you may encounter. Avoid throwing anything into the river. The ecosystem is fragile and protected. Be Cautious of Fake or Unlicensed Tours: Book your boat safari through authorized operators only. Avoid individuals who offer tours at unusually low prices – they might lack safety and environmental standards. Protect Yourself from Sun and Insects: Bring sunscreen, a hat, sunglasses, and insect repellent. The boat safari can last 1–2 hours under direct sun and through mosquito-prone mangrove areas. Dress Modestly at Temple Island (Kothduwa Raja Maha Viharaya): If your boat stops at the temple on the island, remove shoes and wear modest clothing (cover shoulders and knees) as a sign of respect to local customs and religion.
