Sorry lucapal, it wasn´t my intention to mislead anyone but the information is solid as i´ll explain below.
I just got back from the summit climb this morning; 90 minutes from Laban Rata to the top, easy peasy ;-) (i should mention though that i´m what many people would call annoyingly fit for my age (39)
Regarding the one-day climb, i read on several sites that you have to talk to the person at the Sabah Parks Guides counter and arrange a guide there the day before or the morning of the climb.
So i asked three different officials at the Sabah Parks office guide counter and they all had the same answer.
Also, several guides confirmed to me that as of August 1st of this year, it is no longer possible.
Reasons given : opening of the new Lamaing hostel and many people simply couldn´t make it back down before 5PM when Timpohon gate closes.
If there is any "unoffical" person or location inside the park you have to use for the one-day climb, i never read anything about that nor was any such information given to me by any one inside the park.
Finally and most resolute, about two weeks ago, i mailed Sabah Parks informing about my wish for the one-day climb.
Today of all days i received a reply :
"Dear Sir,
It is with regret to inform you that Sabah Parks is no longer offers a one day climb to visitors since the opening of our new Lemaing Hostel at Laban Rata. You can contact our Park Manager at Kinabalu Park, Mr.Justinus Guntabid (email address attached) for reservation.
Thank you.
Yours faithfully,
AK.MOHD.RODZAN HJ.PG.DAHLAN
SABAH PARKS"
FYI, the official website still has to be updated as i also mentioned to Sabah Parks that it´s still possible according to their site ;-)
As for Lamaing hostel, there´s a hot water boiler inside for all your coffee/noodles needs as the food inside Laban Rata cafeteria is expensive; i was quoted RM60 yesterday for dinner though i was told by a traveller it´s buffet all you can eat for 3 hours or so (which can be turned into a deal if you stuff yourself hehe :-d
