You are picked up in the morning with 4x4 from your accommodation, and you are driven inland on the eastern side, where is the end of the Mangrove River. There is a base on stilts (see pic 1), and next to it are the longtail boats sitting on the mud and the kayaks loaded on the bows.
You will have to wait for 30 minutes to 1 hour until the tide will allow the longtail boats to float and cross the mangrove river (see pic 2) to the open sea.
Then the real fun starts, when your longtail boat will take you near small, uninhabited islands and you can kayak around them and enjoy yourselves.
Break for a meal in totally deserted beaches and back at your base in the evening.
A MUST excursion
