Kelantan Darul Naim means "Land of Lightning". This state is managed by 10 administrative jurisdictions: Kota Bharu, Pasir Mas, Tumpat, Pasir Puteh, Bachok, Kuala Krai, Machang, Tanah Merah, Jeli, and Gua Musang.
Kelantan is the most deeply conservative of all Malay states and has with just one interruption been governed by the opposition Islamic Party of Malaysia (Parti Islam SeMalaysia or PAS) since 1958. The party's green flag with a white full moon flutters throughout the state. Highways seem to have more signs with quotes from the Koran than actual traffic instructions; many signs are written in Jawi, the old Arabic script for Malay; and even some Chinese women wear head scarves here.
Whilst Malays make up 95% of the population of 2.4 million and there is also the usual smattering of Chinese and Indians, Kelantan is also home to the Orang Siam, a group of 7,000-8,000 Buddhist Thais. The Thais have lived in Kelantan for centuries.
One strong point that differentiates between Kelantan and the rest of Malaysian states is the way that the Kelantanese categorize people based on their place of origin rather than the color of the skin. All Kelantanese are considered as Oghe Kito (Our People or Orang Kita in standard Malay) no matter which race or religion they belong to. This sometimes gives the wrong impression to the non-Kelantanese Malaysians, to whom the term Orang Kita usually refers to people of the same race.
The Kelantanese dialect of Malay is famously incomprehensible to outsiders, so much so that Kelantanese and non-Kelantanese alike jokingly refer to it as German (pronounced gher-man with a hard G, but yes, it means German). Nevertheless, all Kelantanese learn standard Malay in school, so speakers of standard Malay should not have any problems communicating.
The Orang Siam also speak a dialect of Thai called Tak Bai, but this is also quite different from standard Thai or even the forms generally spoken in southern Thailand.
As for second languages, some people speak English, but do not expect everyone to be able to. And while no-one will expect you to speak Bahasa Kelantan (Kelantan dialect), some knowledge of standard Malay would be very useful.
Kelantan's only airport is the Sultan Ismail Petra Airport (KBR) at Pengkalan Chepa, Kota Bharu. Malaysia Airlines  and Air Asia  provide flights to/from Kuala Lumpur . While people from Penang can reach Kelantan by FireFly.

You can also enter Kelantan on the East Coast main road (Federal Route 3) which runs from Johor Bahru in the south to Kota Bharu via Terengganu and the eastern part of Pahang. Use this road if you are heading to the Perhentian Islands.

A local bus runs twice daily between Gua Musang in Kelantan and Kuala Lipis in Pahang where there are connections to Jerantut for Taman Negara National Park. Buses depart Gua Musang at 1030 and 1530 and from Kuala Lipis at 0800 and 1300. Local buses also run from Pasir Puteh in the eastern part of the state to Jertih and Kuala Besut (for boats to the Perhentian Islands), which lie just inside Terengganu. To Gerik in Perak, there is one trip a day via the East-West Highway, leaving Kota Baru at 0630 and Gerik at 1230.

Kelantan is linked to the rest of Peninsular Malaysia by the East Coast railway line, also known as the "Jungle Railway". The line starts from Tumpat in the north of the state and passes through Wakaf Baru (the nearest station to Kota Bharu), Kuala Krai and Gua Musang in the southern part of the state before it enters Pahang.
The main railway stations in Kelantan where express trains stop are:
To/From Singapore and Johor Bahru: The sleeper Ekspres Timuran goes to/from Singapore daily, also stopping at Jerantut. There are slow local trains to Gemas, Negeri Sembilan where the train joins the main West Coast trunk line, and even to Singapore. In early 2007, a daily day train, the Lambaian Timur was introduced, allowing travellers to enjoy the jungles of Peninsular Malaysia as it travels through the stretch during daylight hours.
To/from Thailand: Although there is a railway branch line running from Pasir Mas to Rantau Panjang on the Thai border, there are no passenger train services into Thailand or even to Rantau Panjang. Catch a local bus to Rantau Panjang, cross the border to Sungai Kolok where the are trains to Hat Yai and Bangkok.

The tallest standing Buddha statue in South-East Asia (108 feet high) was opened to the public in June 2009, at Wat Phothikyan in Kampung Balai, a small village 35 minutes from Kota Bharu, Kelantan.
The temple wall is adorned with a pair of dragon carvings. As you walk in between the two dragon heads at the entrance, you are greeted by a T-Rex statue on your right. But the majestic Buddha statue in gleaming white mosaic tiles really takes your breath away.
Kelantan is famous for its Malay arts and handicrafts (mainly batik). The state's most instantly recognizable symbol is the wau bulan ("moon kite"), which has been adopted by Malaysian Airlines as its logo.
List of things to buy:
Kelantanese cuisine has several specialities rarely seen elsewhere in Malaysia, and most Kelantanese people are very serious about their food. Eating out provides for plenty of options and much cheaper here than the (often not-so-authentic) other versions of Kelantanese food found in Kuala Lumpur. The dominant themes are the heavy use of kerabu, a catch-all term covering various herbs and vegetables and often served as an accompaniment to dishes, and the multiple uses found for coconut, which can be found in almost every dish. Due to its close proximity to the Thai border, Thai food is also widely available; there are also many dishes that are distinct mixtures of Malay Kelantanese and Southern Thai cuisine.
Some specialties worth looking out for include:
Popular desserts and snacks include akok (steamed egg-based mini cakes), bahulu (cakes), "serimuka" (a steamed dessert made from two layers of glutinous rice and pandan-flavored egg custard) and keropok ikan (fish cracker). Certainly there are two or three sweets for every savory dish native to Kelantan-- so you will not run out of things to try. Simply walk around the food section in Pasar Siti Khadijah and you will feast your eyes on various colorful sweet treats. A note of caution though: Kelantanese people are well known for their sweet tooth and even the savory dishes also tend to be cooked on the sweeter side!
Fresh coconut is RM3.
A fermented version of coconut milk is called "tuak", and usually sour. Dare to try.
Kelantan/Kota Bharu is generally safe, and people are generally friendly.
More than anywhere else in Malaysia, in Kelantan it's important to respect local mores, especially if you head out into the countryside. It is not necessary or expected for non-Muslim women to wear a headscarf (though it would certainly meet with approval), but both men and women should wear clothing that covers all or at least most of their legs (no short shorts), and women should wear blouses or dresses which cover their torso. Long sleeves are preferable for women, and outfits which show the shoulders or midriff should be avoided. The watchword is modesty. Tourists dressed in shorts and skimpy tops are really out of place in this state. Regardless of how modestly you dress, if you're white, people may stare at you. If that happens, just smile.
