A one-week itinerary in Thailand typically focuses on a "Best of" route, often splitting time between Bangkok and either the Northern mountains or the Southern islands. A popular 2026 plan involves 2–3 days in Bangkok to see the Grand Palace and Wat Pho, followed by a flight to Chiang Mai for 3–4 days of temple hopping, night markets, and ethical elephant sanctuaries. Alternatively, if you prefer the beach, you can head south to Phuket or Krabi for island-hopping tours to the Phi Phi Islands. For those seeking a more relaxed "week in one spot," the island of Koh Samui offers a perfect blend of luxury resorts and local culture. Because travel between regions can take up a significant portion of your day, it is a peer-to-peer recommendation to limit your trip to two main locations to ensure you spend more time exploring and less time in airports or on buses.
