Cape Piai, Cape and Ramsar site in Pontian District, Malaysia.

Cape Piai is a cape with mangrove forests in Pontian District that holds designation as a Ramsar site. The mangrove trees create dense root systems that shelter local communities from storms while providing habitat for fish and bird species.

Tanjung Piai is one of only five Ramsar wetland sites in Malaysia and the third park designated by the Johor National Park Corporation. Its coastal mangrove was listed as a Ramsar site for its internationally important wetland values, and the site drew 32,360 visitors in 2006.

The cape's name, Tanjung Piai, comes from the Malay words for cape and a local mangrove tree. Seafood restaurants stand on wooden jetties over the water, and the cape is one of Malaysia's five Ramsar wetlands, drawing 32,360 visitors in 2006.

Visitors can explore the mangroves on marked pathways and learn about local plants and animals from information boards along the routes. The driest season offers the easiest access and clearest views through the forest.

The 15-metre light tower stands 0.33 nautical miles south of the cape, at the edge of the drying flats. It flashes once every three seconds and carries a radar transponder beacon that transmits the Morse letter "M".
