It is one of nine islands that made up an eponymous marine sanctuary park offering snorkeling and diving opportunities for tourists.

Of these, 7 islands were protected and gazetted as marine parks by the Department of Fisheries and zoned 2 nautical miles (3.7 km) from the shore at lowest tide.

The largest beach is Pasir Panjang on the east side, featuring half a dozen resorts.

Like the rest of Malaysia's east coast, Redang is affected by the northeast monsoon from the South China Sea, so most resorts are closed and ferry transport schedules are severely restricted between October and March.

By sea, access to the island is from Merang or Shahbandar jetty on boats operated by the resorts.
