Koh Yao Noi and Koh Yao Yai are two large, low-key islands sitting right in the middle of Phang Nga Bay, halfway between Phuket and Krabi — and they're the antidote to the bay's busier stops. Where James Bond Island and the Phi Phi run draw the crowds, the Yao islands stay rural: rubber and coconut plantations, working fishing villages, mangrove-fringed east coasts, and beaches you can often have to yourself. “Noi” (small) is the more visitor-ready of the two, with a handful of low-rise resorts and the kayak route out to Koh Nok; “Yai” (big) is quieter and more agricultural, and feels like Phuket did decades ago. Neither is a theme park — that's the entire point.
We run boats across this bay almost every day, and when guests tell us they want quiet over spectacle, the Yao islands are where we point them. This guide is the version we'd give you on the water: how to get there, what's actually worth doing, when to go, and the from-Phuket-by-sea angle most travel guides miss. It's honest about what the islands are (slow, rural, low-key) and what they're not (nightlife, big resorts, easy ATMs).
As an operator licensed by the Tourism Authority of Thailand (licence 34/02111), running out of Boat Lagoon Marina since 2005, we read Phang Nga Bay's water and weather constantly — which is why the practical advice below leans on the sea route rather than the backpacker ferry-and-scooter loop. The Yao islands sit inside the bay rather than out in the open Andaman, so the crossing is short and sheltered, and the same calm water that makes them a gentle family option also makes them easy to fold into a private day on the bay.
The headline practical fact: the quickest way across is by sea. A speedboat ferry from Bang Rong Pier on Phuket's north-east coast reaches Tha Manok Pier on Koh Yao Noi in about 30 minutes (roughly ฿300 per person; first boat around 8:40am, last around 5pm). If you'd rather experience the bay than just transfer across it, the islands sit on the same sheltered water our Phang Nga Bay boat day works — more on that below.
Koh Yao Noi vs Koh Yao Yai — which one?
| Koh Yao Noi | Koh Yao Yai | |
|---|---|---|
| Feel | Smaller, more visitor-ready | Larger, more rural and agricultural |
| Stay | Several boutique + mid-range resorts | Fewer, more spread-out options |
| Best for | Kayaking, cycling, a quiet 1–2 night escape | Going fully off-grid, plantations, empty beaches |
| Signature | Pasai Beach sunrise; kayak to Koh Nok (~1 mile offshore) | Son Bay & Ao Muang beaches |
For most first-time visitors, Koh Yao Noi is the better base — enough infrastructure to be comfortable, still a fraction of the crowds you'll find on Phuket or in Ao Nang.
What to do
- Watch sunrise over the bay from Pasai Beach — the east coast looks straight out at the limestone karsts; it's the island's signature view.
- Kayak to Koh Nok — the tiny island about a mile off the south-west coast is the classic paddle; kayaks rent from Pasai Beach. Koh Roi is a second option.
- Snorkelling & swimming — the surrounding Phang Nga Bay waters hold reef in patches, with good calm-season visibility. (This is the destination's own water — distinct from the James Bond Island sightseeing route, which is karst-and-cave scenery, not a snorkel stop.)
- Explore by bike or scooter — both islands are flat enough to ride through plantations and villages; cycling is popular.
- Local life — small markets, family restaurants, yoga drop-ins, and a genuinely traditional Muslim-island culture that rewards respectful, modest visitors.
How to get to Koh Yao from Phuket
By public ferry (for an overnight stay): speedboats run from Bang Rong Pier to Tha Manok Pier through the day — about 30 minutes, roughly ฿300 per person, first boat ~8:40am and last ~5pm. To reach Bang Rong, take route 4027 east and follow the Bang Rong signs. Bring cash: ferry and island spending are baht-only.
By boat tour or private charter (for a day on the water): if you want the bay rather than a hotel stay, our Phang Nga Bay & James Bond Island tour works these same sheltered waters — limestone karsts, sea caves, hidden hong lagoons and mangroves, in a small group of max 18 adults (most operators on this route carry 30–60), all-inclusive from ฿4,500 with lunch on board. And because the Yao islands sit right on the bay, a private charter can be routed to take in the Yao islands themselves — your boat, your pace, the calmest stops on the day. See the wider area on our Phang Nga Bay destination guide.
When to go
November to April (dry season) is calmest and clearest — the best window for the bay crossing and for beach time. May to October is quieter and cheaper but wetter, with choppier afternoons; if you go in the green season, keep boat plans flexible. Mornings are calmest on the water.
Local-respect basics (these matter more here)
The Yao islands are traditional, predominantly Muslim communities that have deliberately resisted the bar-and-party model. A few things keep you a welcome guest: dress modestly away from the beach and keep alcohol to licensed venues; bring cash (very limited ATMs); and tread lightly — support family-run places. The unhurried, low-impact culture is the whole appeal.
Where to stay
Koh Yao Noi has the widest choice, from boutique eco-resorts to simple guesthouses. Koh Yao Yai's options are fewer and more spread out — right for travellers who want to be genuinely off the beaten track.
