Koh Yao Yai sits in the middle of Phang Nga Bay — larger and quieter than its more-famous neighbour Koh Yao Noi, and almost entirely off the radar of the package-holiday crowd. If you're based in Phuket and you've done the Phi Phi run and the Similan day trip, this is your next island discovery. It's 30 minutes from Bang Rong Pier, costs almost nothing to get to, and feels like southern Thailand did 20 years ago.
I've been out here a dozen times over six years in Phuket. Some days just for a long lunch and a scooter ride, once for a five-day digital detox in a wooden bungalow with no AC and no WiFi. I've seen expats try to live here full-time. Here's what you actually need to know.
Getting from Phuket to Koh Yao Yai
| Route | Pier | Duration | Cost | Schedule |
|---|---|---|---|---|
| Longtail / local ferry | Bang Rong Pier (north Phuket) | 30–40 min | ฿100–150/person | Multiple daily, roughly every hour |
| Speedboat transfer | Bang Rong / Ao Po | 20–25 min | ฿400–600/person | Peak season daily, by arrangement off-season |
| Private longtail | Any pier arrangement | 35–45 min | ฿1,500–2,500 whole boat | Flexible |
Bang Rong Pier is in the north of Phuket near Ao Po — about 45 minutes drive from Rawai, 30 minutes from Bang Tao. From central Phuket Town, allow 25 minutes. Grab doesn't always reach Bang Rong Pier — take a car, rent a scooter, or arrange a driver. Parking at the pier is ฿50 per day.
The Beaches of Koh Yao Yai
Laem Haad Beach
The iconic sandbar that stretches into Phang Nga Bay at low tide. Best photographed at sunrise or dusk. Not ideal for swimming — shallow, but spectacular scenery with karst backdrop.
Baan Tha Khao Beach
Long, quiet beach on the west coast. Calm water in high season, good for swimming and snorkelling. A few low-key beach restaurants serving seafood. Very little tourist infrastructure.
Lo Paret Beach
Requires a short trek or scooter ride on a rough track. Almost always empty. The kind of beach you have entirely to yourself on a weekday. Basic shade from casuarina trees.
Klong Hia Beach
West coast beach with clear sightlines to the sun setting behind the karst islands of Phang Nga Bay. Small fishing pier gives the view some foreground. Local atmosphere.
A word on managing expectations: Koh Yao Yai's beaches are not Nai Harn or Surin. The water is greenish-murky in rainy season, the sand is fine but not powder-white. What you're here for is the scenery — the karst tower backdrop of Phang Nga Bay, the quiet fishing village atmosphere, the feeling of being somewhere real.
What to Do on Koh Yao Yai
The honest answer is: not much that's formal, and that's the entire appeal.
- Rent a scooter from the pier (฿200–300/day) and just ride — the island is roughly 20km end-to-end and the roads wind through rubber plantations, fishing villages, and rice fields
- Mangrove kayaking — several resorts offer guided kayak trips through mangrove channels on the east coast, with Phang Nga Bay karst views
- Snorkelling trips — the surrounding waters have coral gardens; book via your accommodation or at the pier for day trips to nearby reefs
- Visit Laem Haad at low tide — check tide tables the day before (high tide makes it largely disappear)
- Eat at local seafood restaurants — Koh Yao Yai is a Muslim-majority island (no alcohol at most local restaurants, but some resorts serve it to guests)
- Cycling — the flat inland roads make for good cycling if you bring or rent a bike
Accommodation on Koh Yao Yai
Koh Yao Yai has a reasonable range of accommodation for an island this quiet:
| Type | Price Range (THB/night) | Notes |
|---|---|---|
| Basic bungalows | ฿400–800 | Fan only, shared bathroom, very simple — true budget style |
| Guesthouse rooms | ฿800–1,500 | AC, private bathroom, local family run |
| Mid-range resorts | ฿1,500–3,500 | Pool, sea view, basic amenities, some allow alcohol |
| Boutique resorts | ฿3,500–8,000+ | Koh Yao Yai has a few genuinely lovely eco-boutique properties |
Living on Koh Yao Yai: The Honest Assessment
Some people fall so in love with Koh Yao Yai they consider moving there permanently. A few actually do. Here's what the reality looks like:
- Internet: 4G mobile internet works reasonably well (AIS is best on this island), but speeds are slower than Phuket — 5–20Mbps typical. Fibre is extremely limited. Not ideal for heavy video calls or large file transfers.
- Healthcare: There's a small government health centre on Koh Yao Yai but no major hospital. For anything serious, you need to ferry to Phuket and then get to Bangkok Hospital Phuket (076-254-425) or Siriroj. Factor in 60–90 minutes minimum for emergency care.
- Schools: No international schools. The island has Thai government schools. If you have children needing international education, Koh Yao Yai is not practical for full-time family life.
- Visas: The same Thai visa rules apply as on the mainland. TM30 registration (reporting your address) still required. The nearest immigration office is in Phuket Town.
- Cost of living: Cheaper than Phuket for accommodation but imported goods cost more. Excellent cheap local seafood. Alcohol is available but limited.
- Community: Small expat community — mostly long-term retirees who value the extreme quiet. Very different from the active social scene in Rawai or Bang Tao.
Verdict: Koh Yao Yai works brilliantly as a base for digital nomads between visa runs who want total peace of mind, or for retirees without school-age kids who genuinely prefer isolation and nature over convenience. For families or those who need reliable high-speed internet, Phuket remains the better base.
