The End of the World is not the westernmost part of Penang Island, because the "World" in the context of the townspeople of Penang, is where most of them live. This spans the urban area that starts in Batu Maung - where you can also find the Beginning of the World - and ends in Teluk Bahang.
Take Rapid Penang Bus 101 to the very end of Jalan Hassan Abas. Walk to the bay with the Penang National Park on your left. The spot off the shore is the End of the World. Jutting out into the sea is the Teluk Bahang Jetty.
