You step onto a narrow pier on Koh Yao Yai as a low-slung long-tail boat bobs in blue water, engine ticking like a patient animal. The ride to the Khai islands is short — about 20 minutes — but the ocean immediately changes tone: clarity deepens, schools of silver fish flash, and the three small islets rise from shallow reefs like quiet islands of sand and rock.

You step onto a narrow pier on Koh Yao Yai as a low-slung long-tail boat bobs in blue water, engine ticking like a patient animal. The ride to the Khai islands is short — about 20 minutes — but the ocean immediately changes tone: clarity deepens, schools of silver fish flash, and the three small islets rise from shallow reefs like quiet islands of sand and rock.
The Khai group sits in Phang Nga Bay, a region shaped by limestone uplift and coral growth over millennia. These islets lack big history but sit beside fishing grounds long used by Muslim communities on nearby Koh Yao; local boats still set nets at dawn and bring back lunch that might become your picnic.
Geology here is simple and honest: shallow sand flats, low rocky ledges, and fringing coral gardens. Culture is quietly present — meal packs and friendly guides from Koh Yao Yai — and wildlife is immediate: snorkelers commonly float over parrotfish, sergeant majors, and occasional rays; dolphins have been reported offshore in winter months.
Practical guidance: tours typically collect at 09:00, board by 09:30, and return by early afternoon. Snorkeling equipment is usually provided and the water is shallow and well-suited to families, but bring reef-safe sunscreen, a snug mask, and water shoes for rocky entries. Morning departures are generally calmer; watch for changing wind on the return. Respect coral by not standing on it, carry out all trash, and keep valuables waterproofed.
This short day trip is straightforward: easy travel, clear water, and a compact taste of Phang Nga’s marine life without a long boat day.
The long-tail ride to the Khai islands is typically about 20–30 minutes each way, depending on sea conditions.
