The crossing to the boomerang-shaped island - Pulau Ubin (PU) took around 10 minutes from Changi Jetty which is conveniently situated near  ChangiVillage Bus Terminal. The bumboat (capacity 12 passengers) ride cost  $2.0 one way. Once arriving in PU you can find rows of bike shops with whole-day retail  ranging from $3-$12. We decided to take the $12.00 mountain bike. The owner also gave out copies  PU map ( proved to be next to useless for its ineligible marking).   After verifying  brakes , gears and pedals  were in working condition we hit the paved road. We cycled past 'kampong' houses with corrugated zinc roof. Each  had small plots of lands yielding various fruit trees such as rambutan, nangka etc.  We took a short break at a resting hut in Jln Durian.  Noticing a nearby house we invited ourselves to the compound of a Malay house.  After seeking Mak Chik's permission  we wondered off her garden.  We found the usual fruit trees like rambutan, nangka, durian, chempetak, langsat - the last two were less common in the Singapore Island. I noticed nettings were placed waist-height around the trees which I guessed facilitate easier retrieval of fallen durians. Nearby the yellow-orange bunch of sacara flowers caught my attention.  Just outside her house  - scores of long -tail monkeys were having fun in the Nipah palms. Some even jumped into the blackish water of the canal.
