Nice island where to go for a walk. You can come to the ferry from Kratie with a moto-taxi for 4-5$ and then take the ferry for 100 real.
On the island is easy to walk or bike, there is a paved road that goes all around.
Be careful of the dogs, there are many family dogs that stays in front or inside houses area and most of the time are not controlled. If you go south on the "S" point of the street they will chase you and the people just remain sit without calling them back.
The pagoda at the south point is not that maintained and I have to say it doesn't worth the trip, but that is the turning point if you want to follow the street up on the other side of the island.
Overall visit is nice and people are welcoming.
