Bottle Beach is the best beach in Koh Phangan, and the one people cross the island for. The bay on the north coast is ringed by forested hills. With no proper road down to it, the ways in are a longtail from Chaloklum or a steep trail of about an hour and a half. The other four here each suit a different day: Thong Nai Pan for families, Mae Haad for snorkelling, and Haad Yao and Haad Son (Secret Beach) for west-coast sunsets.
None of them is Haad Rin. The Full Moon Party beach, on the island's south-eastern tip, gets a short note further down, and our guide to the best beaches in Thailand covers it in full. November is Koh Phangan's wettest month, so this guide looks ahead to the dry season that settles in after New Year and runs to April 2027, and to July and August, when the seas are usually calm.
Which side of Koh Phangan has the best beaches?
The north and east coasts have the remote bays, Bottle Beach and Thong Nai Pan. The west coast has the sunsets, more roads and shallow water that can turn a swim into a wade at low tide. That split decides most beach days on the island.
The main ferries from Koh Samui, Koh Tao and the mainland land at Thong Sala on the south-west coast, so the travel times below start from there.
| Beach | Coast | Best for | How to get there | Watch for |
|---|---|---|---|---|
| Bottle Beach (Haad Khuat) | North | A quiet day away from the roads | Longtail from Chaloklum, about 30 min, or a 1.5-hour trail | Boats stop in rough seas; bring cash |
| Thong Nai Pan Noi and Yai | North-east | Families, calm swimming | Hill road from Thong Sala, 25 to 30 min | Steep bends; monsoon swell late in the year |
| Mae Haad and Koh Ma | North-west | Snorkelling, the sandbar walk | Road from Thong Sala, about 25 min | Coral close to the surface at low tide |
| Haad Yao (Long Beach) | West | A long beach with bars and sunsets | Road from Thong Sala, about 25 min | Shallow at low tide |
| Haad Son (Secret Beach) | West | Sunset and a short swim | Road, then a steep lane on foot | Shallow at low tide |
The five are ranked best first, and the best takes the most effort to reach.
Bottle Beach (Haad Khuat), by longtail or the trail from Haad Khom
Bottle Beach faces north into a bay closed off by hills on three sides. A few bungalow resorts line the back of the sand, and almost everyone arrives by boat or on foot.

Longtails leave from the beach at Chaloklum, the fishing village to the west, and take about 30 minutes. Boats run from about 8am to 5pm and go once four or more people are aboard, so a solo traveller may wait. Thai Holiday Guide's July 2026 page puts the fare at roughly 400 baht each way, though it doesn't say whether that is per person or per boat. Agree the price and the pick-up time on the sand before you set off, because the last boats leave in the late afternoon.
The alternative is on foot. A paint-blazed trail climbs over the headland from the Haad Khom end of Chaloklum and takes about an hour and a half. It is hot and steep in places, so carry water and wear proper shoes. Haad Khom, the small beach at the trailhead, is worth a stop either side of the walk.
Bring cash. The beach has no ATMs, and the boats and bungalows take cash only. In rough weather the boats may not run at all, which matters most from October to December, when the wind comes from the north-east and the bay takes the swell.
If the boat and the trail sound like too much, the next pick is reached by road.
Thong Nai Pan Noi and Yai, the twin bays at the end of the hill road
Thong Nai Pan is two bays side by side on the north-east coast, split by a wooded headland. Noi, the smaller, northern bay, has the upmarket resorts. Yai, to the south, is the bigger bay, more open and better for a cheaper bungalow.

Noi is the island's best family beach. The water is calm, with no coral reef to step around, and the resorts on the sand mean food, shade and toilets are never far away. Trails over the headland link the two bays, so a stay on one gives easy access to both.
The road is the price of entry. It climbs from Thong Sala over the island's hills in a run of steep bends, and the drive takes 25 to 30 minutes. A shared songthaew (pick-up taxi) costs 200 to 300 baht a person, according to Thai Holiday Guide's June 2026 page. If you have never ridden a scooter on hills, take the songthaew: the bends are no place to learn, and the road is slippery after rain and unlit after dark.
The northeast monsoon hits this coast squarely from October to December, according to Thai Holiday Guide. The bays are calm in January and February and again from June into September. In the monsoon months, November above all, the sea can be rough enough to cancel the high-season longtails from Haad Rin and Chaloklum.
Mae Haad, on the north-west tip, is also a drive from Thong Sala.
Mae Haad and the sandbar walk to Koh Ma
Mae Haad is the starting point for the island's best-known shore snorkelling. A sandbar runs from the beach to Koh Ma, a small island just offshore, and at low tide it rises clear of the water, so you can walk across.

The tide decides what you do. Walk the sandbar at low tide and snorkel at high tide. Coral starts about 30 metres from the beach, but at very low tide there may not be enough water over it to swim without scraping the reef, Thai Holiday Guide warns in its July 2026 page on Koh Ma. Masks and fins can be rented on the beach, and there is no entry fee.
Mae Haad is about 14km (9 miles) from Thong Sala, around 25 minutes by road through Chaloklum, with a few restaurants behind the sand. The coral sits close to the surface, so don't stand on it, and use a reef-safe sunscreen.
From Mae Haad, the coast road runs south along the west coast, where the island turns to face the sunset.
Haad Yao, where the west coast does sunsets and beach bars
Haad Yao (Long Beach), on Phangan's west coast, is the island's most complete beach resort: a long, shallow bay of white sand with bungalows, beach bars and scooter rental along it. Don't confuse it with the smaller beach of the same name on the east coast, north of Haad Rin.

It faces west across the Gulf, so evenings are the main event, and in January and February the water is calm and clear enough for snorkelling. It is about 25 minutes from Thong Sala by scooter or 30 minutes by songthaew, though songthaews on the west coast are infrequent. The narrow access road can flood after heavy rain.
Swimming here depends on the tide, as it does along most of this coast. The bay is shallow, so you can wade a long way before it is deep enough to swim. Come for a swim around mid to high tide, and for the sunset whatever the tide.
A short ride south, the island's best-known cove does the same sunset in a smaller frame.
Haad Son (Secret Beach), a west-facing cove for sunset
Haad Son is a small cove between Haad Yao and Zen Beach, and it is no secret. It faces due west, so the sun sets straight in front of the sand. Arrive 45 to 60 minutes before sunset to get a spot.

The way in is a short lane off the main road, about 10km (6 miles) and 20 minutes by scooter from Thong Sala. The last stretch is steep and narrow, so park at the top and walk down if you're not confident on a scooter. Entry is free. The Koh Raham bar and restaurant, part of the Haad Son resort, is on the right as you face the sea.
The cove is calm, better for a dip than a long swim, and it can get shallow at low tide. The clearest water is in the dry months.
Three other beaches come up often enough to need a word.
Haad Salad, Zen Beach and Haad Rin, the Full Moon Party beach
None is worth building a day around.
- Haad Salad: a small, quiet bay just south-west of Mae Haad on the north-west coast, which Rough Guides lists among the west coast's sunset bays. Like its neighbours, it is best for a swim around high tide.
- Zen Beach: the west coast's sunset gathering place at Srithanu, with a drum circle, yoga and dancing on the sand. The water is calm and shallow, good for a swim or a paddle, over a mostly sandy floor with rocks and sea urchins in places, so water shoes help.
- Haad Rin Nok: also called Sunrise Beach, the Full Moon Party beach, on the peninsula at the island's south-eastern tip. Haad Rin Nai (Sunset Beach), across the peninsula, is quieter. Our Thailand guide, linked above, covers both bays.
Back on the west coast, the tide matters as much as the beach.
Check the tide before a west-coast swim
Much of Phangan's west coast is shallow. Haad Yao and Zen Beach are shallow, Haad Son can get shallow at low tide, and at Mae Haad the coral comes close to the surface at very low tide. Around high tide the same beaches are fine for swimming and snorkelling.
Before a west-coast day, look up the times for the island on Tide Forecast's Ko Pha Ngan page and plan the swim for the hours either side of high water. If the tide is wrong for the west coast, drive across to Thong Nai Pan Noi, where there is no reef to worry about.
The other thing that decides a beach day is the month.
When to go: Koh Phangan's dry months in 2027
Koh Phangan runs on a different calendar from Phuket and the Andaman coast. Its rain comes late in the year, carried by the northeast monsoon. The Thai Meteorological Department's outlook for November 2026 to January 2027, issued in October 2026, puts the heaviest rain on the east coast of southern Thailand, Koh Phangan's side, in November and the first half of December.
Koh Phangan has no station of its own in the World Meteorological Organization's 1991 to 2020 climate normals. The nearest, on Koh Samui across the strait, gives these averages:
| Month | Rain (mm) | Days with rain | What it means for the beaches |
|---|---|---|---|
| November | 445 | About 17 | The wettest month; north- and east-facing bays rough |
| December | 263 | About 12 | Still wet; boats to Bottle Beach can be cancelled |
| January | 127 | About 9 | Drying out; seas calming |
| February | 64 | 4 | The driest month |
| March and April | 83 to 116 | 5 to 6 | Dry and hot; east-coast bays calm |
| July and August | 102 to 117 | About 11 | Showers, but calm seas |
For a trip booked now, February to April 2027 is the safest window, and January is a reasonable bet if you can live with some showers. July and August 2027 are the second choice: Thai Holiday Guide notes the seas stay calm into September, so the east-coast bays are at their best then too.
If your dates are fixed in November or December, stay on the west coast, where the beaches face away from the northeast wind and the monsoon swell, though the rain falls island-wide. Then treat Bottle Beach and Thong Nai Pan as maybes for a calm day.
Box jellyfish, red flags and what to do if stung
Box jellyfish are found off Koh Phangan. The Tourism Authority of Thailand's jellyfish advice, published in August 2025, lists Ko Pha-ngan and Ko Samui among the areas with occasional reports, and says the jellyfish are more commonly seen in the monsoon months. Protective nets are installed in some places, it says, but not everywhere.
Hotels, beachside restaurants and dive operators must keep vinegar on hand, according to TAT, which also suggests carrying your own. Its first-aid steps if someone is stung:
- Get them out of the water and call the national emergency line, 1669.
- Keep them as still as possible, and don't rub the sting or rinse it with fresh water.
- Pour vinegar over the area for at least 30 seconds.
- Get medical help at once for severe pain, confusion, chest discomfort, difficulty breathing or a change in skin colour, and start CPR if they lose consciousness.
Rough water is the other risk. People have drowned in strong riptides in Thailand, the UK Foreign Office's Thailand travel advice warns. In Thailand, lifeguards work at some designated beaches, a flag system marks safe swimming, and red flags should always be obeyed. Our guide to what beach flag colours mean explains the rest of the set. On Koh Phangan, the northeast monsoon from October to December drives swell onto the north- and east-facing beaches, so check the flags there with particular care. Checked November 2026.
Getting to Thong Sala and around the island
There is no airport on Koh Phangan, so everyone arrives by sea, most of them at Thong Sala.
- Ferries: the operator Lomprayah runs to Koh Phangan from several piers on Koh Samui, from Koh Tao and from Donsak on the mainland, and has a route from Surat Thani airport. Its site gives about 45 to 90 minutes by high-speed boat, depending on the route. It has posted a temporary timetable and pier change from 5 November to 5 December 2026, so check the details before booking in that window. Checked November 2026.
- Songthaews: shared pick-ups wait at Thong Sala pier for the main beaches. Thai Holiday Guide gives 200 to 300 baht a person to Thong Nai Pan; agree the fare before you get in.
- Scooters: the easiest way to beach-hop, with a warning. The Foreign Office says motorbikes for hire in tourist areas are often unregistered and can't legally be used on a public road, so check your travel insurance first.
- Longtails: the way to Bottle Beach, from Chaloklum. They run in calm weather only.
For a first visit with a car or songthaew, the simplest plan is a base on the west coast at Haad Yao, with Haad Son and the sunsets on the doorstep, and a day each for Mae Haad and Bottle Beach. Families should book Thong Nai Pan Noi for February to September and stay put. And if the sea is flat and the boats are running from Chaloklum, go to Bottle Beach first: it is the one day on the island that depends most on the weather.
