A Gulf of Thailand Islands Route: Koh Samui, Koh Phangan, and Koh Tao
Three Islands, Short Ferries, Completely Different Character
Koh Samui, Koh Phangan, and Koh Tao are all in the Gulf of Thailand and connected by relatively short ferries (30 minutes to an hour and a half), making combining all three a logical and very popular route among travelers who already know the southwest and want variety.
Days 1-4: Koh Samui as a Base
A local airport makes it a convenient entry point. Relatively luxurious resorts, the Bophut fishermen's village, and Ang Thong Marine Park as a day trip — an archipelago of 42 small islands in turquoise water. Also worth planning one evening at the Bophut night market, open Fridays only.

A short ferry from Koh Samui. If you want to be part of the Full Moon Party — time it by the date; otherwise, the island's north and west are significantly quieter and calm, and not connected at all to the party image. Worth checking the exact date in advance whether you want to catch it or specifically avoid it.

A small, calm island, known as the cheapest place in the world to learn diving. Even for non-divers, worth a visit — Sairee Beach and the John-Suwan viewpoint with views of two bays simultaneously. The island is small enough to get around on foot or bicycle between most main sites.

If you want to dive seriously (not just try it) in Koh Tao, an Open Water course takes 3-4 days — worth giving it more time than the other islands in the route, not just a day or two. Those planning to book the course in advance should check availability, especially in peak season, since spots in popular courses fill up ahead.
Reverse Order: Start Quiet, End Lively
You can also reverse the order — start with quiet Koh Tao (recover from the flight), continue to Koh Samui, and end at Koh Phangan if you want to be part of a Full Moon Party before the flight home. There's no single 'right' order — depends whether you want to open or close with higher energy, and also depends on your return flight date.
Practically, the Koh Samui airport is the most convenient entry/exit point for all three islands — so most travelers still start or end there, even if the middle order changes. Ferries between the three islands leave several times a day in most months of the year, so planning flexibility is relatively high.
