Update: 21 Mar 2011
Direction signposts with distance are now erected at major junctions which makes easier to get around Pulau Ubin. You may print out a detailed map of Pulau Ubin as free maps are no longer given out.
Sunset at equatorial Singapore is around 7pm so give yourself plenty of daylight time to walk back to Ubin jetty before it gets too dark or to catch the last ferry. Bring a flashlight just in case and jot down emergency numbers from here. Go back the same way from the path you took. Ignore Nparks traffic directions as they are meant for vehicles plus you have to walk up and down 3 slopes.
