The hike up will not be an easy hike, but if you do it slowly and start early in the morning, you will be able to reach near the peak by late afternoon (if you really do it slow n easy). Pack some food & drinks before your hike, unless u dun mind spending more $ to pay for the instant noodles & water along the shops. when you are near the peak, there are two govt-owned guesthouses you can stay overnite for your next morning sunrise. my suggestion, to bring along a sleeping pack, for their cleanliness of their dorm is less desirable as you will like, plus the sleeping bag will also keep u warm in the night.
alternatively, you can take the cable up and climb down, which i did in my trip.
Enjoy the hike, you will need alot of motivation along the way.
