Hi, it's great to hear that you're planning to visit Anuradhapura, Polonnaruwa, and Kandy in Sri Lanka! Here are some tips to make your trip smooth and enjoyable.

Best Time to Visit:
Generally, the best time to visit is from December to April, when there is less rainfall and the weather is dry. However, this period also coincides with the tourism high season, so expect more crowds at major attractions.

Route and Accessibility:
The cities of Anuradhapura, Polonnaruwa and Kandy are well-connected by road. You can travel by car or public bus. There's also a popular tourist train route that connects Colombo and Kandy, offering breathtaking views of tea estates and landscapes.

Accommodation and Booking:
There is a variety of accommodation options across all budgets in these cities, from budget guesthouses to luxury hotels. It's recommended to book your accommodation in advance, especially during peak tourist season. You can use major hotel booking portals or Airbnb for your bookings.

Clothing and Essentials:
Given the tropical climate, lightweight clothes are advisable. Consider packing a rain jacket or umbrella if you're visiting during the rainy season. Don't forget sun protection like hats, sunglasses, and sunscreen. Also, take a pair of good walking shoes for city explorations.

Health and Safety:
Ensure you are up-to-date with routine vaccines before your trip. Tap water is not potable in many parts of Sri Lanka, so opt for bottled water. Always be cautious of your belongings and avoid isolated areas at night.

Local Etiquette and Respect:
Sri Lankans are warm and friendly people. Modesty and respect for local culture and religious places are appreciated. It's essential to dress modestly, especially when visiting temples. Remove shoes and hat before entering temples.
