Moti Daman is located on the western coast of India, bordering the Arabian Sea. It is situated on the southern bank of the Daman Ganga River estuary, where the river meets the sea. The geography is predominantly coastal, defined by flat terrain and sandy beaches.
The physical environment is shaped by its estuarine and marine surroundings, which historically provided an excellent natural harbor. The local flora is typical of India's west coast, featuring coconut groves, palm trees, and coastal shrubs, while the estuarine waters are rich in marine life.
