Having taken a 'taster' trip up to Malaysia's national park (Taman Negara) I decided to take a more serious visit and planned a 3 day trek. This is what I learned from that:
In the jungle:
Leeches are disgusting but harmless, the more tired you are the more you get used to them.
If you stop to pull a leech off your boot, 5 of his mates will sneak up on you.
Leeches move faster than you think.
Trees, big trees, fall down with no warning for no apparent reason.
Monkeys are just small hairy pikeys.
If you think you are at the top of the hill, you're wrong.
If you think it can't get any harder, you're wrong.
If you think you don't have any leeches, your wrong.
If it looks like it wont support you, it won't.
Long trousers and a silly hat keep napa palm spikes at bay, mostly.
It's a rainforest. You're gonna get wet, either from sweat or rain. Accept this and move on.
I hate the taste of water purification tablets. Ever tasted a swimming pool?
You can never carry enough water, even if it does taste like the local baths.
The body can sweat out over 1 litre per hour. Which is the rate I was drinking at. I said you'd get wet.
Dehydration sucks! As do the body cramps that come with it (see point about sweating).
On the way back:
You never knew you could smell that bad, until you take a shower.
Changing a wheel with cramps in arms, legs, back, stomach and even hands, really p*sses you off (especially if it starts to rain while you are doing it).
Malaysian drivers have the sphere of awareness the size of a golf ball.
You get funny looks at the petrol station whilst trying to ease cramps that are preventing you from breathing.
Even McDonalds tastes good!
In summary:
I’d go back tomorrow, provided I could stop walking like I’ve wet myself
If I can figure it out I'll post some photos.
