Tap Mun (Grass Island), up close

Tap Mun, also known as Grass Island, sits off Hong Kong's north-eastern coast near the mouth of Tolo Harbour — one of the more remote inhabited islands, reachable only by a kaido (small ferry) and requiring genuine planning to visit.

Wild cattle

A small population of feral cattle roams freely around the island's grassy slopes, descended from animals once kept by farming families — an unexpected sight and part of what gives the island its English name.

The coastal walk

A loop trail around the island passes wind-swept grassy headlands and dramatic sea cliffs, with views out toward the open water beyond Hong Kong's more sheltered inner waterways — a genuinely different landscape from anywhere covered elsewhere on this site.

Tin Hau Temple

A working temple dedicated to the sea goddess sits near the pier, reflecting the island's fishing-community history.

Getting there

Kaido ferries run from Wong Shek Pier in Sai Kung (see our Sai Kung guide), with limited daily sailings — checking the current timetable before setting out is essential, since missing the return boat means a long wait.
