A trade route is a logistical network for the commercial transport of goods. The period from the middle of the 2nd millennium BCE to the beginning of the common eras saw societies in Southeast Asia, Western Asia, the Mediterranean, China, and the Indian subcontinent develop major transportation networks for trade. This paper focus on trade over bodies of water. The Arabs and Indian merchants maintained a good relationship in the field of trade. The Arabs did not prefer a single trade routes, but they started to find new trading between world. They started step by step moving from one place to other place through sea. This route was used for networks of commercial and noncommercial transportation. This maritime route played significant role on developing good network with Indian people and islands. This trade also helped spread of Islam, Hinduism and Buddhism to the east and west. This Maritime Silk Road opened a road for understanding coastal cultures in the Indian Ocean. My paper throws lights on trade route of Arabs before and after Islam. Not only that trying to review oldest trade routes and islands between Indian and Arabian sea. The same time attempting to read over Arab travelers and their exploring the Indian ocean experiences. The questions about how they travelled and what was the travel strategy, what were goods exported and how they maintained relationship culturally and economically.
