Just camp. Weekdays ok. Weekends pasar malam. A few car camping spots. You can just sleep in the car if you don't want to set up camp.

Can search for AirBnB. Probably better maintained. The 2 bigger hotels, puncak and shaznaz at the clock tower is pretty run down.

Nothing much to do there. If you like hiking and just enjoying the weather will be the primary activities. Food so so. Nothing spectacular. Food at smokehouse also disappointing. The Indian shop at the food court next to the klinik is pretty decent. The Malay shop next to it has some pretty good soup daging/ekor.
