Entertainment options in Negombo are in line with what you'd expect in the area. For instance, there's the opportunity for deep-sea fishing excursions a few dozen kilometers from the coastline. Additionally, you can enjoy a river safari for approximately 20 USD, which involves a boat trip along the banks of the local river. This experience can be combined with agritourism, allowing you to visit local villages and partake in the lives of the locals.
For adult entertainment in Negombo, there's the thrilling option of a helicopter tour to explore various parts of the island. However, this experience comes at a substantial cost - 2 thousand USD for using the helicopter and an additional 112 USD for each hour when the helicopter waits for you while you explore the surroundings. Another exciting option is hot air balloon flights for groups of four people, which also requires a significant investment of 1 thousand USD for an hour and a half of flight time.
