Night camping

camping in pulau ubin

A note on camping at Pulau Ubin beaches. Sandflies are common there. Its stuffy to seal yourself in the tent to escape from biting insects. The acrid smoke from mosquito coils also ruin the tent fabric as the smells and smoky grease stick permanently to it. Camping away from beaches also bring surprises. Once we camped by Kekek quarry and woke up to find giant monitor lizards tearing at food we left outside.

Essential tools
You should always bring along good flashlights with spare batteries and a Swiss army knife with built-in can opener with you.

This way you only need to get essentials from the village provision shop to camp overnight. Here is a short checklist.

  • drinking water (at least 2 large bottles per person)
  • cigarette lighter
  • candles/tealights
  • mosquito coils / spray repellents
  • small can of insecticide (in case of ants invasion)
  • bread/snacks/canned food/instant beverages
  • toilet rolls
  • For extra comfort, here is an added checklist for your next camping trip which you can buy at Changi Village.

  • 2 men tent
  • air or foam mattress
  • light silk blanket
  • small bag of charcoals
  • fire-starter (ask for ‘Tamat’)
  • bbq wire grill
  • aluminum tray
  • metal tong
  • disposable cups/plates/chopsticks/spoons
  • Trash bag/paper tissues
  • metal mugs
  • chef blow torch
  • Camping checklist

    With these, you get hot food, hot drinks and warmth for the night.

    The aluminum tray holds the charcoal embers which you can douse with water for safe disposal. You can move it closer to you for added warmth later on. Never place them on wooden tables or boardwalks floor. It will burn through. Nparks is forced to erect uncomfortable cement tables and benches because of such thoughtless act by campers.
    For food. Try bread with charcoal grilled luncheon meat which is delicious and easy to prepare. Make sure food are secured beyond reach of foraging animals before you sleep or go on a hike. Rubbish should not be left lying around for the same reason. Tie them in bags and hang them high on branches if the rubbish bin is full.

    Preparing charcoal fire

    Light a single piece of fire-starter (the locals call it Tamat) and place it at the base. Tamat takes a while to burn out so one or 2 is enough. It is also sooty so make sure it is burnt out completely before grilling food.

    Stack long pieces of charcoals leaning against each other over the fire starter. Done correctly, the charcoals will combust into flames without fanning. Spread the burning charcoals and let the flames die out. The embers is sufficient to grill food.

    Turn often to ensure food are not burnt. Wear a headlamp to see better and check if the food is ready.


    Chef blow torch

    Another tool we find useful is a chef blow torch (picture above). A better alternative than camp gaz stove (picture below). It is compact and the gas refill last a long time and replacements are easily available. You can boil water within minutes or use it to stop invading ants or clear your bed area of creepy crawlies. You can buy the blow torch at shops selling kitchen aids or at hardware shops. Get the original Japanese iwatani brand which cost about S$40.

    Air Mattress vs Hammocks

    Sleeping outdoors can be a challenge. Hard sleeping surface makes one turn about in discomfort. I bought a Therm-a-Rest air mattress to improve sleeping comfort. This air mattress is too expensive, bulky and takes too long to deflate. Foraging ants is another problem while sleeping on ground.

    Eagle Nest Hammock

    A high quality hammock like The Eagles Nest SingleNest Hammocks is able to bear loads up to 180 kilos. A generous safety margin is needed as the whole system is subjected to uneven weight stress. Like most hammocks sold, they don’t come with suspension ropes which needs to be just as strong. You’ll need about 4 meters lengths at each ends. For this I bought military grade 1″ tubular webbings to wrap around trees without strangling or damaging them. To create a quick release system, I bought 2 pairs of suspension rings from a ship hardware shop in Sungei road. Do watch youtube videos and read camping forums on how to set hammocks correctly and safely.

    You can buy Eagles Nest Hammocks and tubular webbings locally from Sheares Marketing.


    Jelutong Campsite.

    Jelutong campsite is located a few hundred metres next to Ubin village facing the bright lights of Singapore. Although convenient and recommended by Nparks, it takes one further away from enjoying the fun of frontier adventurism which Ubin is famous for. Do camp at Noordin or Marman beach and leave Jelutong camp for kids and those who are scared of darkness.

    Durian season

    Durian season 2010
    The durians in Ubin are dropping at its peak. It will be all over in a week or so. We camped overnight determined not to miss out. The durian trees nearby are known to have the best tasting durians.

    Unlike commercially harvested durians, Ubin durians are harvested from the jungle floor as the ripe ones drop, sometimes from a great height, its spiky skin strong enough to absorb any hard landing.

    We can only hear muffled thuds so its not easy to locate durians by sound. The first step is shine our flashlights at the tree to check where the durians are hanging in numbers, this will give us an idea where to look as they roll hidden in the bushes. Still, they are easy to miss, you need a keen nose to catch a slightest whiff, so we would not consume any durians until the hunt is over in order to preserve maximum sense of smell.

    Suddenly a durian dove straight towards us. There is no time to react, it shatters right between us with a loud thump. The durian exploded inches from my feet, bounced and spikes into my friend’s calf, drawing blood. We have been lucky, it could have smash our faces as we looked up. The durian was already rotting. Durians get watery and some rot on the branches from too much rains.

    The durian that nearly hit us.

    The rains also brought in mosquitoes in huge numbers, we covered ourselves with expensive spray repellents and planted no less than 10 mosquito coils around our camp area, having run out of egg cartons to burn.

    Although the harvest is plentiful, we were contented with 7 durians. Other diligent groups got more. There are small shelters built under the trees, keeping the occupants dry and safe from falling durians. Others use electric bikes, criss-crossing the island revisiting each durian grove.

    ————————
    Took leave. Camped overnight for the past 2 weekends. We heard that Ubin durians are beginning to fall and were excited. Unfortunately we were too early. There were unriped durians on the grounds with teeth marks. Like us humans, monkeys are also excited and plucked the durians too early before they ripen. We sheepishly accepted durians from Mr. Lim, a Ubin villager staying at Marman “Orchid farm”.

    We were again unsuccessful on the second week. There were durians pickers camped under the trees. One sat motionless for hours, coming into life on sounds of durians dropping. They would race towards the spot where they heard the durians drop. These people must have heard tales of thousands of dollars earned picking free durians. There is a family of 10 brothers earning $10,000 picking free durians or $1,000 for each brother. Small sums for many but there are lots of poor folks in Singapore.

    We only managed to get one before they came running over. During to the rainy season and the cooler weather this year, the durians were watery and bland, quickly fermenting within space of several hours, unlike the previous seasons where they tasted a lot better.

    It looks like we have to go to remote parts of Ubin for our durian hunt.

    Durian seasons come to Ubin twice a year. The major one lasts a few weeks and no one knows the exact dates. The first sign is the abundance of durian flowers, indicating the season is about to due in a few months.
    Some durians will fall earlier but these are usually premature durians. Fully ripened durians will fall a few weeks later and lasting for about 6 weeks. Other tropical fruits also ripen at the same time including rambutans, mangosteens, dukus and langsat.

    Ubin durians are a treat. In the midst of the hot season, the durians are expected to be more fragrant too They are your organic varieties having been left abandoned by islanders who resettled a long time ago. Being older varieties without the benefits of modern cultivating techniques, Ubin durians are tough to open with flavors that vary from tree to tree. Use gloves and a “durian knife” to pry open.

    During durian season, entire families would converge heedless of snakes that may hide in the bushes. Ubin villagers usually wear “phua chu kang” boots to protect themselves while gathering durians. Some even use umbrellas to protect themselves from falling durians.

    Q. Why durians drop at night
    Durians drop during the day too, although more at night. From the same tree, its durians will drop over several weeks, but sometimes they hang tantalizingly for weeks and are suddenly gone in a week or so. Once ripen, the frequency seems to in favor when temperatures dip or rise quickly when night come or when dawn breaks. Strong gusts of wind will also bring about unexpected bonus. Which is why picking durians is a waiting but rewarding game.

    As durians usually drop at night, there are brave ones who stake out at cemeteries waiting for the loud thuds of durians falling. You need a trained eye plus a strong flashlight to find them as they roll into shrubs and bushes.

    Update: 19 June 2010.
    Durians are beginning to fall and we were excited for a night of adventure and durian hunting. Have bought a couple of new flashlights to try out including my favorite lights. They include:

    Zebralights H60 Headlamp 18650 Flood.
    HDS CR123a Ra Clicky ExecutiveTM Flashlight (General purpose)
    Quark CR123x² Turbo (For throw)

    I am bringing LED lights for its weight, excellent run-times, super brightness, and good color rendition. Qualities that are essential for durian searching.


    If you intend to find some. Just follow your nose and look for them on the forest floor. Sometimes you hear a lucky thump of durians which has just fallen. Make sure you rent a bicycle with basket, like this lucky couple did. You also need repellents to deter mosquitoes from feasting on you.

    Don’t congratulate yourselves too soon if you find durians on the floor. They are probably bad if they are discolored and smell a bit off, Those with bites marks are from frustrated monkeys who cannot get through the though shell.

    Unseen, the wild boars are waiting too. During the night, they would push the durians against the forest floor with their tough snouts until the durians split open like flower petals. By morning only empty husks remained. Many ‘ghosts encounters’ were results of mistaking these pigs or islanders trying to scare people away from collecting durians.

    Although durian gathering can be fun, there are ‘geylang types’ from mainland Singapore who act as if the trees are theirs. They would intimidate others including Ubin villagers who come near, loudly proclaiming their ‘ownership’. Its not true of course.

    Off! Insect Repellent

    The first time I use ‘Off” insect repellent was in Taman Negara National Park. Then it wasn’t the mosquitoes that bother us but leeches. We would spray our ankles with them to stop the leeches from crawling up our legs.

    The mosquitoes in Ubin can be torture. The solutions we tried include burning egg cartons, coconut husks, mosquito coils, smoky benzoin incense which bomohs use, ingesting vitamin B and vitamin E tablets. Nparks even set a high tech mosquito killing machine once.

    In the interest of science, I took vitamin B pills for one month and went into the bush without repellents. It seems to be working initially. Then all of a sudden the mosquitoes were all over me. Its 4 days since and I am still scratching

    Nothing beats the convenience of using spray repellents containing DEET. My eight year old nephew is allergic to insect bites and he has to be sprayed all over. For face and neck, just spray them in your palm and rub to avoid stinging your eyes. No point spraying until wet. They are expensive and soon empty fast. Spray a little mist and repeat a few hours later.

    They costs S$8.50 at major outlets. Some provision shops sells them for S$7.50 each. They are a lot cheaper in Indonesia. Autan is also a popular brand there.

    Update: 21 Apr 2009. Prices of “OFF!” repellent seems to go up all the time. Its now $8.50 at Guardian pharmacy. I am going to switch to 3M “Ultrathon”, which is also used by armed forces worldwide. Although it costs nearly the same, it contains 25% DEET, which won’t get washed away quickly when you are sweating in the jungle heat.

    Update: 1 Apr 2010
    Watson’s price for Off! and Ultrathon repellent is most reasonable so far at about $7.50 for Off! and one dollar more for Ultrathon.
    Update: 23 Jun 2010.
    Ultrathon is now ridiculously priced $9.60 at Watson.

    Mosquito Coils

    Mosquito coils are probably the cheapest and easily available form of insect repellent. It works by producing smoke which drives mosquitoes away. Mosquitoes coil from approved brands like Baygon contain active compounds like Transfluthrin, a synthetic chemical compound similar to the natural chemical pyrethrins produced by the flowers of pyrethrums for “knock down effects” but not killed.

    Baygon mosquito coils
    It look like a puzzle to a first time user. Taken out, each piece look like a spiral pancake which are actually 2 coils stuck together. The trick is to carefully pry them loose without breaking them. I would start from the center and slowly separate by shaking them loose.

    There is one metal coil stand included in each box of 10 coils. It come flattened so push the centre to form a ninety degree stand. Light the coil with a candle for about a minute and put it on the stand. Depending on wind and humidity, each coil should last about eight hours.

    Mosquito coils were invented in Japan in 1890 and they are most widely used today, with 29 billion mosquito coils are sold each year and 95% used in Asia. (see link)

    Mosquito coil stand

    You need more coils placed in open spaces toward the wind for maximum cover. We would put up five or more coils as the wind change directions through the night. You can check if you have enough smoke cover by shining an LED torch.

    As there are only one coil stand per box, improvised stands need to be made as the coils will soon stop burning if placed on flat ground. A little height is needed. The coils should not be placed in the open as jungle dew will soon smother them.

    Do not put them in your tent either. You’ll will soon choke with acrid smoke and your tent will soon be smoked with oily residues and become unusable because of the lingering smell.

    Do not throw away the stands but save them for your next camping trip.
    Keep the coil stands for future use

    You can also buy portable coil holders that clamp the coil with inner mesh and can be carried around. With it, the coils can also be burnt at both ends to generate more smoke.

    Some people believe that burning coils is like inhaling 100 cigarettes. In that case you can improvise by making smoke with less pungent alternatives like egg cartons and coconut husks. Make sure you put out the flame after lighting it, the egg carton will smolder. Cut the egg carton in halves and lay them in line to extend the smoking time.

    Buring egg cartons

    Make sure coconut husks are dry as it does not burn well.
