Koh Yao Yai

The one that tourism mostly skipped

Koh Yao Yai is the bigger of the two Koh Yao islands in Phang Nga Bay, but it receives far fewer visitors than its smaller neighbor Koh Yao Noi. The reason is largely logistical: the ferry from Phuket’s Bang Rong Pier takes 90 minutes to reach Koh Yao Yai compared to 60 minutes to Koh Yao Noi, and Koh Yao Yai has even less tourism infrastructure to reward the extra journey. There are a few guesthouses, several local restaurants, and a main road connecting the villages — and that’s mostly it.

Where	Phang Nga Bay, ~35 km east of Phuket
Getting there	Ferry ~90 min from Bang Rong, or 10 min by longtail from Koh Yao Noi
Time needed	1–2 days, often as an add-on to Koh Yao Noi
Cost	Around 150 THB ferry, 100–150 THB longtail from Koh Yao Noi
Best time	November–April for calm crossings

What this means in practice: you can cycle down a road with Phang Nga Bay karst scenery on one side and rubber trees on the other, stop at a local market selling grilled corn and fresh coconut, and not see another foreign tourist for several hours. For a specific type of traveler — one who came to southern Thailand and is tired of organized beach tourism — this is genuinely valuable.

The island has a long west-facing beach (Hat Yao, which means “long beach”) that stretches for several kilometers in relative quiet. The swimming is good in calm conditions; the sea views include the limestone towers of Phang Nga Bay. A handful of beach chairs and food stalls operate here during high season.

Getting there and around

The most efficient approach is to stay on Koh Yao Noi for 2–3 nights and take a day trip to Koh Yao Yai by longtail (10 minutes, roughly 100–150 THB per person on a shared boat, or 400–600 THB for a private longtail). This way you use Koh Yao Noi’s better guesthouses as a base while still seeing Koh Yao Yai.

If you want to stay on Koh Yao Yai itself, accommodation is basic — basic guesthouses from 500–1,000 THB per night. The one mid-range option with a proper beachfront setting is Koh Yao Yai Village Resort, which has bungalows and a pool at around 2,000–3,500 THB per night.

Motorbike rental is the standard way to see the island (250–350 THB per day). The main road is paved; several tracks through the interior are dirt. Cycling is possible but the distances are larger than Koh Yao Noi, and the flat terrain across paddy fields and plantations is less scenically concentrated.

What to see and do

Hat Yao (Long Beach): The main beach on the west coast runs for roughly 5 km with minimal development. The water is calm, the sand is reasonably clean, and sunsets facing toward Phuket are reliably vivid. This is the most photogenic part of the island for casual visitors.

Local village life: The main settlements are Ban Tha Khao on the south coast (nearest to the Koh Yao Noi ferry crossing) and Ban Lo Pa Yai further north. Local markets operate in the morning. The Muslim fishing community is the same demographic as Koh Yao Noi — modest dress and respectful behavior around mosques is appreciated.

Phang Nga Bay views: From several elevated points on Koh Yao Yai, particularly near the north tip, the limestone karst panorama of Phang Nga Bay is visible. These viewpoints are less famous than those on Koh Yao Noi (and therefore less visited) but comparable in quality.

Snorkeling and kayaking: There’s modest reef around the island’s south tip and near some of the smaller islets visible from the east coast. Kayaks are rentable from one or two operations on Hat Yao during high season. This isn’t a dive destination — for serious underwater activities, Racha Island or the Similan Islands are the right choices.

Food, cash and staying connected

Eating options are basic and local: a handful of family-run restaurants near Ban Tha Khao and Ban Lo Pa Yai serve pad thai, fried rice, and grilled seafood at local prices (60–120 THB per dish), plus a small morning market selling fruit and snacks. There’s no restaurant strip in the Phuket sense — most kitchens close by early evening, so plan dinner rather than assume something will be open.

Cash is non-negotiable here. ATMs are limited to one or two machines near the main pier and can run dry on busy weekends; card acceptance outside the Village Resort is close to nonexistent. Bring enough baht from Phuket or Koh Yao Noi to cover your whole stay. Mobile signal is present but patchy away from the villages — a Thai SIM bought in Phuket before crossing is the sensible move, since nothing is sold locally.

Combining with Koh Yao Noi and Phang Nga Bay tours

The standard Koh Yao region itinerary from Phuket: one night in Koh Yao Noi (or two), with a morning day trip to Koh Yao Yai by longtail, and a Phang Nga Bay kayaking tour either from Koh Yao Noi or as part of a return journey to Phuket. This covers both islands, the bay’s most photogenic sites, and uses the ferry/speedboat network sensibly without too much backtracking.

Honest assessment: who Koh Yao Yai is actually for

Koh Yao Yai is specifically good for travelers who:

• Have already been to the main Phuket beaches and want something different
• Want to see working rural island life without the package-tourism overlay
• Are staying on Koh Yao Noi and want to explore both islands

It’s not a good choice for first-time visitors to Thailand looking for Andaman island experiences. The lack of facilities means you need to be comfortable with basic options, and the island’s appeal is largely in its absence of things — no crowds, no beach clubs, no organized tours every 20 minutes — rather than in specific attractions.

Frequently asked questions about Koh Yao Yai

How do you get to Koh Yao Yai from Phuket?

The regular ferry from Bang Rong Pier on Phuket’s northeast coast takes about 90 minutes and costs around 150 THB. Alternatively, take the faster 60-minute ferry to Koh Yao Noi and then a 10-minute longtail between the two islands. Speedboats are also available from Bang Rong for faster travel at higher cost.

Is Koh Yao Yai bigger than Koh Yao Noi?

Yes — despite being the less visited island, Koh Yao Yai is larger in area and population (approximately 8,000 residents vs. 6,000 on Koh Yao Noi). The extra size means more cycling distance, more empty beaches, but also more sparse infrastructure.

What is the main beach on Koh Yao Yai?

Hat Yao (Long Beach) on the west coast is the main beach — several kilometers of open shoreline with calm water and sunset views toward Phuket. It’s significantly less developed than most Phuket beaches, with only a small number of beach chairs and food stalls.

Is there nightlife or entertainment on Koh Yao Yai?

No. Koh Yao Yai has no nightlife infrastructure. The island is a predominantly Muslim fishing community and strictly follows local customs. Restaurants near the pier may serve beer, but bars and entertainment venues don’t exist here. If nightlife is part of your travel plan, stay in Patong or Phi Phi.

Can you do a day trip to Koh Yao Yai from Phuket?

Technically yes, but the 90-minute ferry each way leaves limited time on the island. A more practical approach is to base yourself on Koh Yao Noi (60 minutes from Phuket) and day trip to Koh Yao Yai by longtail (10 minutes from Koh Yao Noi). This gives you adequate time to cycle around and have lunch.

Is Koh Yao Yai safe for solo travelers?

Yes — the island is safe. The community is welcoming. The main concern is the lack of tourist infrastructure: if you have a medical emergency or mechanical issue with a rental motorbike, assistance is limited. Solo travelers should have travel insurance and a basic plan for communication. Mobile signal is present in the main villages.

What’s the best way to combine Koh Yao Yai with a Phuket itinerary?

Allocate one full day from Phuket, or ideally spend 2 nights on Koh Yao Noi and include a morning on Koh Yao Yai by longtail. On the return journey, some speedboat operators allow routing through Phang Nga Bay to include a stop at James Bond Island before returning to Phuket — check with operators at the Koh Yao Noi pier.

Are there ATMs or card payment on Koh Yao Yai?

There’s a small number of ATMs near the main pier, and they can run out of cash on busy weekends and holidays. Card acceptance outside the Village Resort is minimal. Bring enough baht from Phuket or Koh Yao Noi to cover your whole visit, including motorbike rental and meals.

Can I rent a motorbike on Koh Yao Yai?

Yes — a handful of shops near Ban Tha Khao and the pier rent motorbikes for around 250–350 THB per day. This is the practical way to cover the island’s larger distances compared to Koh Yao Noi, since the flatter terrain makes cycling less scenic and more of a slog. Bring cash, as rental shops rarely take cards.
