Another favourite activity in Amphawa is firefly watching at night. Boat tours for the firefly watching are available along both sides of the canal. When the sun goes down and darkness falls, the water surface will be calm and the cool breeze will blow gently. On the banks, you’ll see thousands of tiny lightening bugs partying all over the mangrove and sonneratiacaseolaris trees . This creates a very romantic ambience. Firefly watching can be done all year round, preferably the waning moon nights of the rainy season (May-October). The trip normally starts at 6.30 pm. and lasts about an hour and a half.
