Tiger Hill, Flagstaff Hill, Haliburton's Hill, Fern Hill, Strawberry Hill, and Government Hill. Flagstaff Hill is above sea level. A number of small rivers and streams originate from the region. Sungai Pinang (Malay for Penang River) is the largest of the rivers, and it starts from a number of tributaries in the area. Land use Because Penang Hill has a cooler environment, it has been a popular holiday retreat. A number of bungalows were built around Flagstaff Hill. The northern part of the Hills are not well developed. Government Hill, Bukit Timah (Malay for Tin Hill) and others are designated water catchment areas and no development is permitted. Some recreational potential exists at the upper reaches of the river where the water is relatively clean. In a number of cases, sudden changes in ground level have resulted in a series of small waterfalls and rapids, where bathing, dipping and picnicking are popular. The lower terrain of the Hills is used mainly for agricultural and residential purposes. Accessibility The most convenient way up to Penang Hill is by means of the Penang Hill Railway, a funicular railway from Air Itam to the top of Flagstaff Hill. The journey used to take about half an hour and the train may stop at intermediate stations upon request. However, upgrades to the system now allows non-stop rides to the top in five to ten minutes. For Malaysians, the fare for a return (round-trip) ticket is RM12 per adult and RM6 per child aged between three and 12. For foreign tourists, the return fare would be RM30 for adults and RM15 for children aged seven to 12. Senior citizens and students will enjoy cheaper fares at RM6 per person. The ride continues to remain free of charge for disabled persons holding the OKU (Malay acronym for Orang Kurang Upaya) card. Penang Hill residents, licensed traders and hawkers and workers can purchase a monthly season pass at RM28. The blue, air-conditioned Swiss-made coaches, capable of ferrying up to 100 passengers at one go, run from 6:30am to 11pm daily. The ticketing counter opens at 6:30am and will be closed at 10:30pm daily. Alternatively, there is a tarred road known popularly as the "jeep track". It is open only to the vehicles of hill residents. The "jeep track" is also used by off-road motorcycle enthusiasts to traverse up the steep terrain. It is a popular hiking route.
