The name "Tachai" isn’t random — it carries a meaningful legacy. The island is named in honor of Khun Chaiyapruk Poonsawat, a well-known environmentalist who was instrumental in promoting the protection of this area. Thanks to his efforts, Koh Tachai became part of a national park in 1988 (B.E. 2531). In tribute, locals and travelers began calling it “Koh Tachai,” combining the Thai word “Ta” (meaning “Uncle” or a respectful elder) with his name, Chai.

To enjoy Koh Tachai at its best — clear waters, sunny skies, and no rain — timing is everything. Unlike many other islands, Koh Tachai is not open year-round, which is actually a good thing. This seasonal closure helps preserve its untouched beauty.

💡 Fun Fact: March to April is the peak season for snorkeling. The calm waters provide excellent visibility, and the marine life is at its most vibrant. If you're a snorkeling enthusiast — this is the time to go.
