Planning your first trip to Thailand in 2026 should start with checking the updated visa-free entry rules, which currently allow citizens from over 90 countries to stay for up to 60 days. A classic 7-to-10-day itinerary for beginners typically includes the urban energy of Bangkok, the cultural temples of Chiang Mai, and a relaxing island like Phuket or Koh Samui. The best time to visit is during the "cool season" from November to February for dry, comfortable weather. Budgeting is flexible: $30–$50 per day for backpackers or $120+ for luxury stays. Use the Grab app for reliable transportation and avoid "special tours" offered by street tuk-tuks to prevent common tourist scams. Don't forget to pack modest clothing (covering shoulders and knees) for temple visits and ensure you have an eSIM or local SIM card for easy navigation. Booking through ethical sanctuaries is also highly recommended if you plan to visit elephants.
