Ever. Ever ever ever. In a million years.
If you happen to pass through Kampot on the Cambodian coast at any time please resist the urge to do a trek up to Bokor Hill Station unless you have a death wish. You used to be able to get a moto or a truck all the way up there which I imagine would have been pleasant, but now Chinese developers have closed the access road so the only way up is an absolutely hellish two-and-a-half-hour vertical climb through dirt roads and jungle.
You are literally scrambling up rocks and dirt paths in 40 degree heat covered from head to toe in sweat for what seems like an eternity. Seeing as the trip starts at 8am I made the fatal error of not having breakfast either and consequently almost fainted at one point. We lost one guy about half an hour in because he thought he was actually going to die.
After you finally, breathlessly make it to the top you are obviously expecting something fantasmical to await you..... but no. Being as it's dry season all the waterfalls are dried up so all we did was spend an hour walking around half a dozen disused buildings. Cue another two-and-a-half-hours on the way down sliding all over the place on your arse desperately trying to avoid toppling over a cliff edge.
Don't. Just Don't.
