The dumbbell shaped Saint Martins island (সেন্টমার্টিন) has an area of about 8sq. km. But the main island has an extension in the South and is named as Chera Dip (ছেড়া দ্বীপ / Isolated Land). It is little isolated from the main land but you can go by walking during low tide. The small island is full of coconut (নারিকেল) trees from which the name originated. It can also be explored by boat. Engine boats are available in Saint Martin. It takes about 1 hour to reach in Chera Dip.
