Hello! That sounds like an exciting trip. Here's what you need to know about visiting Kelantan, Terengganu, and Pahang:

Best Time to Visit:
The best time to visit these regions, which are in east Malaysia, is typically between March and October, when rainfall is at its lowest. However, it's good to note that these months also coincide with the tourist high season.

Route and Accessibility:
There are direct flights from Kuala Lumpur to airports in Kelantan (KBR), Terengganu (TGG), and Pahang (KUA). You can also access these regions by bus, train, or car from Kuala Lumpur, depending on your preference.

Accommodation and Booking:
Booking in advance, especially during high season, is advised. There are many choices for accommodations available in these areas, including luxury resorts, budget hotels, and homestays. Websites like Booking.com or TripAdvisor can help find the best suitable option for you.

Clothing and Essentials:
Pack lightweight and breathable clothing due to the tropical climate. A good raincoat is a must if you're travelling during the monsoon season. Also, ensure to bring sunscreen, insect repellent, and a good pair of walking shoes.

Health and Safety:
Always drink bottled water as tap water may not be safe. Use mosquito repellent to prevent mosquito-borne diseases like dengue fever. The public healthcare system in Malaysia is generally good.

Local Etiquette and Respect:
Malaysia is a predominantly Muslim country, and modest dressing is appreciated, especially in more conservative areas. Remove shoes when entering homes and mosques. Being polite and respectful to locals goes a long way in ensuring a pleasant journey.
