Essential Travel Tips
Reserve flights 3-4 weeks ahead, trains 1-2 weeks ahead, and ferries 3-7 days ahead for best prices and availability.
Ferry weight limits and frequent transfers make light packing essential. Focus on essentials and buy items on the island.
Long bus and train journeys require proper hydration. Bring water bottles and take advantage of stops to refresh.
Book first night only, then explore options on arrival. Island accommodation ranges from budget hostels to luxury resorts.
Check weather conditions before ferry travel. Rough seas can delay or cancel departures, affecting your schedule.
Bring sufficient Thai Baht for transportation, meals, and tips. ATMs exist but may charge fees or run empty during peak times.
