Should I book all my ferries in advance?

No. Book only your first transfer online. Buy subsequent ferry tickets 1-2 days ahead once you're on the islands. This gives you flexibility if weather cancels services or you want to stay longer somewhere.

Can I island hop during rainy season?

Yes, but expect ferry cancellations and rough seas. Andaman Sea is particularly choppy May-October. Gulf islands are more manageable year-round, though September-November sees heavy rain.

How much time should I spend on each island?

Minimum 2 nights to make ferry transfers worthwhile. Koh Phi Phi and Koh Tao deserve 3-4 days. Small islands like Koh Lipe work as 2-day stops. Factor in half-day travel time between islands.

Is it cheaper to book ferry packages or individual tickets?

Individual tickets are usually cheaper and more flexible. Ferry packages lock you into fixed schedules. Exception: joint tickets from Bangkok including bus/train + ferry can save money if you're certain about timing.

How to plan a Thailand island hopping route

Start with Bangkok or Phuket as your gateway, then choose either the Andaman Sea islands (Phuket, Phi Phi, Krabi) or Gulf of Thailand islands (Koh Samui, Koh Phangan, Koh Tao). Allow 2-3 days per island and book ferries as you go rather than fixing everything in advance.

Choose your island chain. Pick either Andaman Sea (west coast) or Gulf of Thailand (east coast). Andaman has dramatic limestone cliffs and better diving. Gulf has calmer waters and famous Full Moon Parties. Don't try to do both unless you have 3+ weeks.
Pick your gateway city. Fly into Bangkok then take connecting flights to Phuket (Andaman) or Koh Samui (Gulf). Or fly into Bangkok and take the overnight train to Surat Thani for Gulf islands. Phuket and Krabi work for Andaman access.
Map your route logically. For Andaman: Phuket → Phi Phi → Krabi → Koh Lanta. For Gulf: Koh Samui → Koh Phangan → Koh Tao. Always move in one direction to minimize backtracking and ferry time.
Allow proper time per island. Budget 2-3 days minimum per island. Koh Phi Phi and Koh Tao need 3-4 days. Small islands like Koh Lipe or Koh Nang Yuan can be day trips from larger bases.
Book flexibly. Only book your first 2-3 nights in advance. Buy ferry tickets 1-2 days ahead once you're there. This lets you adjust timing based on weather and your preferences.
Plan around weather. Andaman Sea: Best November-April, rough seas May-October. Gulf of Thailand: Best December-April, rainy season September-November. Check ferry schedules during rough weather periods.
