Tours which take in Sepilok Orangutan Sanctuary often also visit the nearby Labuk Bay Proboscis Monkey Sanctuary.
Take a 5min detour drive to Taman Hiburan Jalil Alip (http://www.jalilalip.com/), a local recreation park popular among locals, to fish, paddle boats and feed local species of deer and crocodiles in their individual sanctuaries in the park.
