Quick practical notes

• Best seasons: South & west coast (Galle, Bentota, Colombo) are best Nov–Apr; east coast (Arugam Bay, Trincomalee) best May–Oct due to monsoon patterns. Hill country and the Cultural Triangle are visitable year-round but can be cooler/wetter in certain months. (Monsoon guidance summary). (thetimes.co.uk)
• Book early for peak season (Dec–Mar) and for small properties (many have <30 rooms). Expect higher rates and limited availability around Christmas/New Year and local long weekends.
• Look for what matters to you: heritage (Kandy House, Grand Hotel), wellness (Santani), eco/sustainability (Jetwing Vil Uyana), beachfront boutique (Saman Villas, Cape Weligama), or safari + beach combos (Chena Huts).
• How to book: check the hotel’s official site for best-room types and direct offers; compare availability and cancellation terms on major OTAs (Booking, Expedia) and consider contacting the hotel directly for transfers or special requests.
