I had a stop in this little town because of I was interested in the dolpins. The dolphins can usually be seen right from the river bank, but it’s worthwhile to take a spotting cruise in one of the wooden long-tail boats available for hire.
But I couldn't see about them toooo much, unfortuntely. The locals said this is better in the early morning, but in the middle of the day they are "lazier". :o)
