Loads of different boat companies. Our driver recommended Captains Boat House & it was great. 3000 each for private boat & friendly excellent English speaking guide. Showed us many birds/ cattle/ water monitors/ lizards/ fish. Interesting visit to Cinnamon Island. Made me necklace from water lily. Stopped for King Coconut too. Could see other boat companies with loads of crammed in passengers & shabby boats. If doing this river safari look for Captains Boat House.
