Mount Kinabalu is Borneo's tallest mountain. You can climb to the top of Low's Peak (4,095.2m or 13,435.7ft above sea level). The height of the mountain is often given as 4,101m but recent satellite imaging has proven this to be incorrect.
The mountain is sacred to locals. They believe that spirits of their ancestors inhabit the top of the mountain. Previously, a chicken was sacrificed at the peak every time a climb was made but these days this ceremony only happens once a year when only seven chickens are needed to appease the spirits.
Mount Kinabalu is known to be one of the most accessible mountains in the world. No specialized mountain climbing skills are required to ascend it. The trail that most tourists use is described as a 'trek and scramble'. Locals begin climbing the mountain from the age of 3 and the oldest person to reach the peak was 80 years old. However, how much one enjoys the climb depends strongly on how fit you are and how well you acclimatise to the thin air at the higher levels.
Nevertheless, the mountain can be a dangerous place, especially during the rain or when there is mist. On average, every year one person gets into severe difficulty out of the estimated 20,000 people who attempt the climb. The higher slopes can be very slippery when it rains and dense fog reduces visibility to a few feet.
Although it is possible to climb to the top and back in less than four hours, most climbers take two days, with an overnight break at Laban Rata (3,272.7m above sea level). The final attack on the peak takes place in the early hours of the second day (most begin at 2:30AM) in order to catch the sunrise at the top. By mid-morning the mist begins to roll in, obscuring the breath-taking views.
Climbing weather is best around the month of April while November and December brings rain. The temperature ranges from a comfortable 20-25°C at the main park to something approaching freezing near the top (depending on the weather). Bring clothing appropriate or else you will get cold and be miserable. If possible, climb during the full moon as it helps illuminate the white rope that marks out the climbing path.
The Kinabalu Park entrance is very easy to reach from Kota Kinabalu. Catch minivan from the Long Distance Bus station (near Night Market, city centre), minivan leaves when its full, cost RM15 each way. It will take you to the Park HQ. Buses (Coach)leave every morning - just ask your hostel/hotel or around the bus station (Kota Kinabalu North Bus Terminal in Inanam, 10km to the northeast of the city centre.) Buses going to Ranau, Sandakan or Tawau will pass by the park entrance. It's best to leave before eight - if you're lucky you'll catch a beautiful clear view of the mountain outside the left-hand side of the bus as you approach the park. The journey should take 1-2 hours and should cost between RM10-RM15.
You can also catch buses from Sandakan (a six hour journey).
An alternative is to take a long-distance shared taxi at Taxi station near Jalan Padang. A ride between Kota Kinabalu and the park should cost RM15-RM18 each way. Taxis will only depart once they are full, though, which usually means they have seven passengers(Toyota Unser), so you may have to wait a while. Alternatively you can pay for the missing passengers and leave immediately.
Regular (i.e. non-shared) taxis in Kota Kinabalu try to offer their services for RM150-200 or more for one-day drives to the park and back. Given the ease with which one can travel by public bus or shared taxi, however, this is an unneccessary option for budget travelers.
Self-drive is another option with car hire readily available at Kota Kinabalu airport. Driving is an easy option for those accustomed to driving on the left hand side and gives the option to stop at things en route. Car hire rates are negotiable so compare rates on offer from the various companies. The distance to the park entrance is just under 100km from Kota Kinablu cetnre, with the last 40 or so km being a sparesley populated mountain road. There is very little road signage directing you to Kinabalu Park, and there are a number of highway intersections en route (despite the fact that the route appears very simple on the map). The best option is to buy a fold-out road map at one of the bookshops in Kota Kinabalu, note down the towns en route to the park, and follow the road signs past those towns.
For the more adventurous traveller, the trip can be done on a hired motorbike. Be aware that there will be no petrol stations on the mountain road (the final 40 or so km of the trip), and you should ensure you have enough fuel for the journey to the park and back.
Non-Malaysians pay RM15 (adults)/RM10 (children) to enter the park. (Malaysians pay RM3 and RM1 respectively). There is another RM120 fee (plus RM7 for insurance) to climb the mountain in addition to park entry.
Alternatively, you can climb from Mesilau Nature Resort. The trail is 2 km longer than the one that begins from the park entrance but is less steep overall.
Climbing the mountain
Well preparation is needed in term of physical and mental fitness as to ensure successful in reaching the summit. Activities such as jogging and stairs climbing up and down should be done at least 2 months before the climbing (if no prior preparation, you can still reach the summit but it will be strenuous). Also practise carrying 5kg of weight during stairs climbing.
Bring adequate medical equipment i.e. band aid, ankle/ knee guard, plaster, paracetamol, anti-vomitting pill, muscle cream and etc. Wear the band aid before climbing up and down to avoid muscle pain.
A briefing will be provided by guide at 6pm daily before the climb begin.
The actual climb is made along a well-marked path with signposts marking each half-kilometre. All who climb the mountain must buy a climbing permit (RM100/RM40 for non-Malaysian adults/children or RM30/RM12 for Malaysian adults/children) provided that accommodation for Laban Rata has been arranged.
The park also strongly advises all to hire a guide. A guide can cost between RM85-RM120 per trip - the actual cost depends on the number in the group and which route is used. (It is possible to climb without a guide, but a waiver needs to be signed.) Insurance will also be required for the climb.
In addition to all this, there is also a bus that takes climbers from the park entrance to where the climbing path properly begins (RM5 each way per person). Those that choose to not take the bus face a 5km hike along a tarred road.
There are periodic rest stops about a kilometer apart up the mountain. The entire journey is 8.72km, with a stop about 6km up at Laban Rata where most climbers will stay overnight. Usually, the climb started at 7.30-10.30 am. The first 4km climbing to Laban Rata is in moderate steep where the trail is equipped with stairs and some rock path. The last 2km is tough with solely rock path. Average person reached at Laban Rata (6km journey) is 4-5 hours (some unfit person will reach in 7-8 hours).
The ascent from Laban Rata upwards is difficult in places, including climbs along steep ledges, and usually starts at around 2-3AM. It can also get very gusty in places as the vegetation barrens near the top. The severely unfit will find it almost impossible.
You should bring waterproof and warm clothing including a hat and gloves, with spare, dry clothing packed in waterproof bags. If you get wet at altitude you will quickly get cold. You should also wear proper walking shoes. Bring a good headlamp with extra batteries (a headlamp is preferred over a torch since you will need your two hands for climbing some rocks near the summit), a whistle and plenty of high calorie food such as nuts and chocolate. A disposable rain coat is adequate and avoid to bring heavy bag. Unnecessary clothing and equipment can be left at counter before starting your climbing.
Here is a synopsis of the costs involved for a solo non-Malaysian adult staying in a budget mountain hut bed:
Via Timpohon Gate:RM16.50/way(1-4 persons) RM4/person (5 persons and above) Via Mesilau Trail:RM85.00/way(1-6 persons) RM15/person (7 persons and above)
Starting 1st Jan 2012 RM290(Malaysian) & RM485(International) per person for Dormitory (Inclusive 1 packed lunch, buffet dinner, breakfast and lunch)
To minimize costs, you can take the following measures:
Note that you might not be charged for the park entry fee.
Kinabalu Park is home to a diverse array of flora and fauna that changes in nature as your altitude increases. Near the top of the mountain the trees thin out and give way to shrubs, stones and fabulous views. Around km 4.5 there are some large pitcher plants off the trail; a well-informed guide will know where they are.
Climbing the mountain is strongly encouraged, but be forewarned that it can be strenuous. Also, it is best to book accommodation beforehand — indeed, the hike has become so popular that you may have to book months in advance. The park can be very full especially during clear weather periods. Note that it is not possible to stay overnight on the mountain except in the accommodation provided at Laban Rata, and camping is not permitted - you must, therefore, have pre-booked accommodation. (See Sleep for details.) However, sometimes there are cancellations. If you are unable to book mountain hut accommodation in advance, get to the Park HQ as early as possible on the day of your intended climb and inquire there. You may luck out and get a bed. By regulation, booking must include guide services.
As you struggle up the mountain, do look out for porters laden with 14 kilogram gas cylinder tanks. Some wear slippers and most have jury-rigged harnesses (some made of rice sacks) piled high with supplies. The porters scale the 6.5km distance between Timpohon Gate and Laban Rata resthouse several times a day on supply runs and can easily outpace better-equipped climbers who are unfamiliar with the trail.
Once you complete the strenuous hike up to 11,000ft, you might have enough energy to do the only via ferrata ("iron road", a set of cables and ladders bolted to the mountain)  to be found in Asia, which happens to be the world's highest. It is still relatively unknown so take the opportunity to do it without a crowd of people pushing you. There are 3 different paths to take on the via ferrata, with times ranging from 4-5 hours for the longest to 2-3 for the shortest. Keep your travel plans in mind when booking the via ferrata and after-mountain activities, as this time is added to the 4-5 hours it takes to descend the mountain on the second day of hiking.
For the more advenurous and physically fit, there is also an option to climb to the summit and down in one day. This is not widely publicised - presumably to maintain patronage at the expensive mountain huts. To arrange this, you should speak to the park ranger at the park office - turning up in person is generally more effective, so that the ranger can see that are serious and is less likley to fob you off than if you were to enquire by phone. The one day climb is more weather dependend than the two day option, and there are set time limits for each stage of the climb which must be met, otherwise the rules say you will be turned around (it's not clear whether this actually happends, but be aware that the time limits would require you to climb at a reasonable pace). You will be required to hire a guide. You can expect to start at 0730 and will be required to come down by 1730 before the Timpohon Gate is locked. Because the one day climb will bring you to the summit well after sunrise, you should consider the sesonal weather patterns - at times, the mountain top clouds over shortly after sunrise and you may not get a view from the summit. The climb to the summit is almost 2300m, and the one day climb is physically tough. Nevertheless, it is achievable, and during the Mt Kinabalu Climbathon  top runners complete this route in under 2 hours 40 mintues.
There are cafeterias and restaurants both at the Park entrance gate and at Laban Rata. The food prices at Laban Rata are relatively higher compared to prices at nearby towns. This is because raw materials need to be carried up to Laban Rata by porters. For example, a buffet dinner of 6 different dishes costs RM33; a can of beer is a whopping RM20; tea is RM6. The quality of the food is good, however.
However, if you don't feel the need to stuff your face, you can bargain with the staff and get one plate of rice/curry chicken for RM 15.
To save money, you can stock up on bread, baked goods, chocolate and other lightweight but energy-giving foods in KK before you depart. It is good to bring your own supply of instant noodles and tea sachets as well as snacks, though be warned that in the cafeteria they will charge you RM1 for hot water! Some huts have electric kettles where you can boil your own water for free.
However, from 1st Jan 2008, all climbers are charged for mount resort food. They will provide you with four meals. This is inclusive in the hotel's rates. First day lunch is provided for takeaway (to be eaten on the way to Laban Rata) during breakfast. Normally they will provide 3 set of sandwiches, fruit, eggs and 1 piece of chicken.
For climbers from Timpohon or Mesilau Gate, they must reached at Laban Rata before 7.30pm for buffet dinner or else they need to pay by themselves. While for buffet breakfast, the end time is 10.30am before you start your journey back to Timpohon or Mesilau Gate.
Water, that is. During the hike to the top it's important to stay well hydrated. Fortunately, at each pondok (rest pavilion) on the trail, there's large tank of free drinking water constantly being fed by pipes leading down from clean water sources high up on the mountain. The tanks are marked "Untreated Water", but the water is safe to drink. Thus, it's unnecessary to bring lots of heavy bottles of water along; one container will suffice.
Formerly administered by Sabah Parks all accommodations in the park must now be arranged through Sutera Sanctuary Lodges, a private company,  Tel: +60-88-303917 Fax: +60-88-317540 firstname.lastname@example.org). Note: Be advised that Sutera (a.k.a. Sutera Harbour) is requiring hikers stay the first night at their lodge near the entrance. This is in addition to a required stay at Laban Rata at about 11,000 ft. The cost to stay is considerably higher than at lodging just outside the park, and includes a mandatory purchase of meals etc.
UPDATE APRIL 2011: All huts and Laban Rata now cost 415RM for a 60 bed dorm. Since 2009, there has been a problem with the electricity, leaving all rooms unheated and with cold water. A small generator does provide some lighting. There doesn't seem to be any plans on fixing this in the near future. (If they do fix it, a dorm bed at Laban Rata will cost 475RM.)
