Thong Krut Beach, Koh Samui Pier for Pig Island Boats and Seafood

Overview

Thong Krut Beach (หาดทองกรูด) sits on the far southern tip of Koh Samui, Thailand, roughly 20-25 minutes from Nathon and about 45 minutes from Samui International Airport. Unlike the resort strips on the east coast, Thong Krut is a working fishing village first and a beach second: a narrow bay of colorful longtail boats, seafood shacks, and quiet village life that has changed little in decades.

What draws most visitors here isn’t sunbathing. Thong Krut Pier is the main departure point on Samui’s south coast for island-hopping trips to Koh Tan (also spelled Koh Taen) and Koh Madsum (better known as Pig Island), plus access to the wider Ang Thong Marine Park archipelago further offshore. Longtail boat operators have run trips from this pier since the late 1980s, and the pace of the place still feels closer to a fishing community than a tourist stop. Our Koh Samui long tail boat guide covers prices and what to check before boarding.

The beach itself stretches about 1.5 km along the coast, with the Ring Road (Route 4170) running only about 30 meters from the shoreline. The sand is coarse and mixed with pebbles and coral fragments rather than the fine powder of Chaweng or Maenam, and the shallow, rocky seabed means Thong Krut is better known for boats and seafood than for swimming.

History: A Working Fishing Village

Thong Krut has always been defined by the sea, but not in the way most Samui beaches are. While the east coast turned to tourism in the 1980s and 1990s, Thong Krut’s economy stayed anchored to fishing. Families here have worked the waters around Koh Tan and Koh Madsum for generations, and the multicolored wooden longtail boats moored along the bay are still used for both fishing and passenger trips.

The village’s tour trade grew out of that fishing tradition rather than replacing it. Local operators such as TK Tour Samui, which says it has run boat services from the pier for more than three decades, started by ferrying fishermen and cargo before expanding into snorkeling and island-hopping trips as word spread about the reefs around Koh Tan. Today the pier area mixes working fishing boats with tour longtails, and it’s common to see nets being mended a few meters from where tourists board for Pig Island.

Because Thong Krut never had the flat, wide sand that attracted big beach resorts, development stayed modest: a handful of small hotels and guesthouses rather than international resort chains. That has kept the village’s character largely intact: a genuine, low-key slice of the south coast rather than a manufactured “authentic village” experience.

The Beach: Sand, Tides, and Swimming

Thong Krut Beach runs for about 1.5 km between the neighboring stretches of Thong Tanod and Bang Kao, in the Taling Ngam sub-district on Samui’s southern shore. At high tide the beach is roughly 7-15 meters wide; the sand is coarse, mixed with small pebbles, shell fragments, and pieces of coral rather than the soft, fine sand found on the north and east coasts.

Is Thong Krut Beach good for swimming?

Not especially. The seabed shelves out very gradually, shallow water extends a long way offshore, and at low tide much of the nearshore area is exposed rock and sand flat, which locals and visitors alike describe as unattractive for a swim. The bottom near shore also has patches of stone and coral debris, so reef shoes are worth packing if you do wade in. Families with small children will generally find the calmer, sandier water at nearby Taling Ngam Beach or Lipa Noi Beach more comfortable for swimming.

What Thong Krut’s beach does offer is a working waterfront view: rows of multicolored longtail boats bobbing at anchor, small wooden piers, and sunset light over the water toward Koh Tan and Koh Madsum in the distance. It’s a beach for photos, seafood dinners, and boat departures more than for laps in the sea.

Island Hopping: Gateway to Koh Tan and Koh Madsum

This is Thong Krut’s main draw. The pier sits directly opposite two small satellite islands that have become some of the most photographed day-trip destinations near Samui.

Koh Tan (Koh Taen)

A largely undeveloped island roughly 30 minutes away by longtail boat, Koh Tan has shallow fringing reefs in about 2-5 meters of water with typical visibility of 5-10 meters. Expect to see parrotfish, butterflyfish, angelfish, sea urchins, and starfish, with occasional sightings of green sea turtles. The island has a handful of simple beach bars and not much else, which is largely the point.

Koh Madsum (“Pig Island”)

About 10 minutes further by boat from Koh Tan, Koh Madsum is famous for a small colony of free-roaming pigs that wander the beach and swim out to greet arriving boats. Most tours let visitors feed them bananas, watermelon, or vegetables from the shallows. Beyond the pigs, Koh Madsum has a quiet white-sand beach and a second, smaller snorkeling spot.

Thong Krut Pier to Koh Madsum: booking a boat

Longtail boats can be hired directly at Thong Krut Pier or booked through restaurants that double as tour desks. A private half-day longtail charter for a small group typically runs ~3,500-6,000 THB (~100-171 USD) depending on the boat and itinerary, while joining a shared group tour with hotel transfer runs closer to ~2,800 THB (~80 USD) per adult and ~1,400 THB (~40 USD) per child. An entry fee of about 50 THB (~1.50 USD) per person, paid in cash on arrival at Koh Madsum, is usually not included in tour prices. Morning departures around 9 AM generally get calmer water and better light for photos.

Activities and Boat Tours

Thong Krut is built around the water, and most activities here connect back to a boat.

• Island-hopping day trips: the main activity, combining Koh Tan snorkeling with a stop to feed the pigs on Koh Madsum. Half-day and full-day options are both common; see the Koh Madsum and Koh Tan day trip guide for prices and operator tips.
• Snorkeling: bring or rent gear for Koh Tan’s shallow reefs; visibility is best in calm, dry-season conditions.
• Fishing charters: several operators, including TK Tour Samui, offer half-day and full-day fishing trips around the southern islands.
• Kayaking: some tour packages pair a longtail crossing with kayaking around Koh Tan’s sheltered coves.
• Ang Thong Marine Park access: while most Ang Thong tours depart from Nathon or Bangrak, some southern operators run charters from Thong Krut out toward the 42-island archipelago; ask locally, as this is less standardized than the Koh Tan/Koh Madsum run.
• Village walks and photography: the working pier, drying nets, and stacked fishing traps make for an authentic contrast to Samui’s resort beaches.

For hikers exploring the island’s interior on the same trip, the Ang Thong Wua Talab Viewpoint hike is a different way to see the same Mu Ko Ang Thong National Park archipelago from above, on a separate boat-and-hike day.

Thong Krut Koh Samui in Half a Day

A half day covers the pier, the island trip and a seafood lunch.

1. Arrive around 8:30 AM and agree the boat price, inclusions and return time at the pier.
2. Depart about 9 AM for Koh Tan (about 30 minutes), then Koh Madsum (about 10 minutes further), carrying cash for the entry fee.
3. Return for a seafood lunch on the bay (about 400-700 THB for two, as of 2026).
4. Add Laem Sor Pagoda or sunset at Taling Ngam on the way back.

Full prices and operator tips are in the Koh Madsum and Koh Tan day trip guide.

Where to Eat: Thong Krut Seafood Scene

Thong Krut’s dining reputation outweighs its size. The bay is lined with small, family-run seafood restaurants built right at the water’s edge, several of which are considered among the best value seafood spots on Samui.

What to order

Grilled whole fish, steamed crab, stir-fried squid with basil, and prawns grilled or in tom yum soup are the standard order here, all sold at prices well below the equivalent dish in Chaweng. A full seafood dinner for two with rice and a couple of Chang beers typically runs ~400-700 THB (~11-20 USD), noticeably cheaper than beachfront dining on the east coast.

Price guide

• Budget: Noodle and rice dishes from ~60-100 THB (~1.50-3 USD)
• Mid-range: Fresh seafood plates ~150-400 THB (~4.50-11 USD)
• Groups: Whole grilled fish or crab by weight, typically ~300-800 THB (~8.50-23 USD) depending on catch and size

Nearby Attractions

Under 10 minutes

• Taling Ngam Beach: about 10 minutes west, a quieter sunset beach with views toward the outer islands.
• Samui Snake Farm / Wildlife Rescue: a small local charity a short drive from the pier.

Under 20 minutes

• Laem Sor Pagoda: a golden chedi built directly on the shoreline, one of the more photogenic temple stops on the south coast. The small cove beside it has its own guide: Laem Sor Beach.
• Wat Khunaram: home to Samui’s famous mummified monk, seated in a glass case inside the temple grounds.
• Lipa Noi Beach: a long, quiet stretch further west, popular for sunsets over the Gulf of Thailand.

Where to Stay

Thong Krut has far fewer beds than Samui’s east coast, which is exactly why some travelers seek it out. Options lean toward small hotels, guesthouses, and private villas rather than international resort brands.

Because the area has “only two resorts” directly on the beach itself, with a couple more just behind the Ring Road, most visitors either stay in nearby Taling Ngam or Lipa Noi and drive in for the boat trips and seafood.

Getting There

From Samui Airport (USM)

Thong Krut is on the opposite side of the island from the airport, so allow around 45 minutes by car or taxi, longer in heavy traffic. Airport taxis use fixed zone fares (500-1,500 THB island-wide; confirm the zone for Thong Krut at the counter, see the Koh Samui airport guide). A Grab booked once you’ve left the terminal also works.

From other beaches

• From Nathon (ferry port): ~20-25 minutes via the Ring Road.
• From Taling Ngam: ~10 minutes.
• From Chaweng or Lamai: roughly 40-50 minutes around the south of the island.
• From Lipa Noi: ~15-20 minutes.

Driving in

Route 4170, Samui’s Ring Road, runs about 30 meters from the shoreline through Thong Krut, so the beach and pier are easy to spot from the road: look for the cluster of longtail boats and a local police booth marking the turn down to the pier.

Getting around

There’s no need for a scooter once you’re at the pier: everything worth seeing in the village is walkable. To reach nearby beaches and temples, a rented scooter (~200-300 THB/day, ~6-9 USD) or car (~1,200-1,800 THB/day, ~36-54 USD) is the most practical option, since public songthaew routes are less frequent on this side of the island than on the north and east coasts.

---

Best Time to Visit

Boat operators generally recommend December to August for the calmest crossings to Koh Tan and Koh Madsum and the best underwater visibility. September through November brings Samui’s wettest, choppiest conditions, and island-hopping trips are more likely to be cancelled or rescheduled at short notice.

---

Practical Tips

• Book boats in the morning: 9 AM departures usually mean flatter water and better snorkeling light before the afternoon wind picks up.
• Bring cash: small seafood shacks and boat operators in the village mostly deal in cash, not cards.
• Wear reef shoes: the rocky, coral-flecked seabed near shore is uncomfortable barefoot, especially at low tide.
• Check the tide table: swimming directly off Thong Krut Beach is only worthwhile close to high tide.
• Confirm trip inclusions: ask whether snorkeling gear, lunch, and hotel transfer are included before agreeing a price for a longtail charter.
• Sun protection: there’s little shade on the open longtail boats used for island trips; bring a hat, reef-safe sunscreen, and water.

FAQ

Is Thong Krut Beach good for swimming?

Not really. The seabed near Thong Krut Beach is shallow and shelves out gradually, with a rocky and coral-flecked bottom that’s more comfortable close to high tide. Most visitors come for the boat trips and seafood rather than swimming, nearby Taling Ngam and Lipa Noi beaches offer sandier, calmer water for a proper swim.

How do I get to Koh Tan and Koh Madsum from Thong Krut?

Longtail boats depart Thong Krut Pier for Koh Tan in about 30 minutes, with Koh Madsum (Pig Island) roughly 10 minutes further on. You can hire a private longtail charter for around 3,500-6,000 THB (~100-171 USD) for a small group, or join a shared tour with hotel transfer for around 2,800 THB (~80 USD) per adult.

How far is Thong Krut Beach from the airport?

About 45 minutes by car, since Thong Krut sits on the opposite, southern side of Koh Samui from Samui International Airport. It’s roughly 20-25 minutes from Nathon ferry pier and about 10 minutes from Taling Ngam.

What is Koh Madsum, or “Pig Island”?

Koh Madsum is a small island near Thong Krut famous for a colony of free-roaming pigs that swim out to meet arriving boats and are commonly fed bananas or vegetables by visitors. It also has a quiet white-sand beach and a smaller snorkeling area, and is usually visited together with Koh Tan on the same boat trip.

What food is Thong Krut known for?

Fresh, affordable seafood. Small family-run restaurants along the bay, including Nuch’s Green Ta’lay Restaurant and The Beach Restaurant, serve grilled whole fish, steamed crab, and stir-fried squid at prices well below Samui’s east coast beaches, often eaten with a cold Chang beer at the water’s edge.

How much is the Koh Madsum entry fee from Thong Krut?

About 50 THB (~1.50 USD) per person, paid in cash on arrival at Koh Madsum. Operators usually do not include it in the tour price, so carry small notes. Boat fares from Thong Krut Pier are separate: roughly 2,800 THB per adult on shared tours, or 3,500-6,000 THB for a private longtail.

Is Thong Krut worth visiting if I’m not doing a boat tour?

It’s still worth a stop for the seafood and the atmosphere of a genuine Samui fishing village, but the main reason most travelers come to Thong Krut is the boat trip to Koh Tan and Koh Madsum. Without a tour booked, plan on an hour or two for lunch and a walk along the pier rather than a full beach day.
