Samut Songkhram Nature Trip
Don Hoi Lot–Fireflies–Coconut Farms

Samut Songkhram is Thailand's smallest province, but if you like quiet, low-key nature, it packs a lot into a drive of just over an hour from Bangkok. We've laid this out as a 2-day, 1-night trip: walk the river-mouth sandbar at Don Hoi Lot, take a boat into the Khlong Khon mangroves, stop at a coconut farm to watch locals boil down fresh palm sugar, then finish with an evening boat ride to see fireflies along the lamphu trees. It's an unhurried pace, good for anyone who wants a break from the city.

Samut Songkhram Nature Trip Don Hoi Lot–Fireflies–Coconut Farms

🔄 Updated 21 Jun 2026

Mae Klong and Amphawa are best known for their floating market and the famous Maeklong Railway Market, but the real charm of this province is its three-water geography — fresh, brackish, and salt water all meeting at the mouth of the Mae Klong River. Because of that, you get coconut groves, mangrove forest, and an estuary sandbar all in one province. This nature trip strings those three together: daytime is split between the gardens and the sea, and the nighttime firefly outing is saved to close out the day.

One thing to know before you go: a lot of the boat activities here run on the tides and the season, especially the fireflies, which come out in numbers from the rainy season into early winter (roughly June–October). If you can, come on a Friday–Sunday, since the firefly boats and Amphawa Floating Market only operate on weekends.

Day 1 — River mouth, mangroves, and fireflies after dark

Day 1

Don Hoi Lot → Khlong Khon → Amphawa Floating Market → firefly boat

08:30

Leave BangkokIt's about an hour and a half via Rama II Road to Mae Klong town. Without a car, you can catch a Bangkok–Mae Klong minivan from the new Southern Bus Terminal (Sai Tai Mai).

10:00

Walk the Don Hoi Lot sandbarThis sand-and-mud bar sits at the mouth of the Mae Klong River. At low tide it surfaces in a wide flat, and locals head out to gather razor clams using lime. It's a nice spot to stroll and catch the sea breeze. Check the low-tide schedule before you go and the bar will be far more exposed.

11:30

Seafood lunch by the barSeafood restaurants line the road from the entrance all the way to the Krom Luang Chumphon shrine. Spicy stir-fried razor clams, Mae Klong short mackerel, grilled prawns — mid-range prices, around 120–250 THB a dish.

13:30

Mangrove boat at Khlong KhonAt the Khlong Khon Mangrove Conservation Centre you take a longtail boat winding through the mangroves to see crab-eating macaques, shorebirds, and cockle farms. Some groups also do mud-sledding to collect cockles and replant mangroves. Contact the community tourism group ahead of time and it goes more smoothly.

16:30

Check in around AmphawaThere are riverside homestays and resorts set in the gardens at a range of price points. Drop your bags and rest a bit before heading out in the evening.

17:30

Walk Amphawa Floating Market for dinnerAmphawa Floating Market runs Friday–Sunday, from afternoon into the evening. There's food all along the canal — grilled river prawns, fried oyster omelette, Thai sweets. Graze your way through before getting on the boat.

19:00

Firefly boat along the lamphu treesBoard at the municipal pier near the bridge over the canal. Tickets are around 60 THB/person, or about 400–500 THB to charter a whole boat. It takes you along the Mae Klong River to find lamphu trees where the fireflies cluster and blink. The trip runs about 45 minutes to an hour.

What to know about the fireflies

Fireflies are living creatures, not fairy lights. Some nights there are loads, some nights only a few, depending on the weather and the water. Moonless nights with no rain are when they show up best. Don't shine bright torches at the lamphu trees, as it disturbs them, and pick a boat that switches its lights off while you watch, so the blinking stands out more.

Day 2 — Coconut farms, palm sugar, and a café in the grove

Day 2

Coconut farm → sugar stove → garden café → home

08:00

Early morning by the canalIf you're staying at a waterside homestay, get up to watch locals paddle by. On some canals you can still catch people giving alms to monks who come by boat.

09:30

Visit a coconut farm to see sugar tappingAmphawa's raised-bed orchards grow aromatic coconuts and sugar coconuts. In the morning, farmers climb up to collect the sweet sap from the coconut flower stalks — a traditional way of life that's still genuinely practised here.

10:30

Watch fresh coconut sugar being boiledSugar stoves in the community boil the sap over firewood until it thickens into solid palm sugar, filling the shed with a sweet, toasty smell. You can taste the fresh sugar warm and buy some to take home — the real thing, straight from the source.

12:00

Local lunchTry sour curry with short mackerel, fried Mae Klong mackerel, or stir-fried morning glory with fresh prawns at the orchard or canal-side restaurants — bold, homey flavours.

13:30

Café in a coconut groveAmphawa has several cafés set among the raised-bed coconut orchards, shady and relaxed. Many use local coconut sugar in their drinks and desserts. It's an easy place to sit before heading back.

15:30

Pick up souvenirs and head homeThe nature-trip souvenirs here are solid palm sugar, Mae Klong mackerel, and seasonal fruit from the orchards. You'll make it back to Bangkok well before dark.

Packing for a nature trip

Check the tides — Don Hoi Lot looks best at low tide, when the sandbar is widely exposed, while the Khlong Khon and firefly boats are easier at high tide. Look up the tide times for the upper Gulf of Thailand before setting your schedule.
Come Friday–Sunday — Amphawa Floating Market and the firefly boats only operate on weekends. If you come midweek, there may be no firefly boat running.
Firefly season — they come out in numbers from the rainy season into early winter (roughly June–October). Moonless nights with no rain are clearest; in the dry season you may see fewer.
Shoes and sun protection — the sandbar and mangroves are muddy underfoot, so wear shoes you don't mind getting wet or that slip off easily. Bring a hat and sunscreen, as the coastal sun is strong.
Book boats ahead — for the group mangrove boats at Khlong Khon, contact the community tourism group in advance. You can buy firefly-boat tickets at the pier, but on busy weekend nights it's worth arriving early.

You can do it in a single day

If you only have one day and want to focus on nature, do Don Hoi Lot in the late morning, Khlong Khon in the afternoon, then the firefly boat in the evening — skip the coconut farm for now. That gets you both the sea and the fireflies in one day, but you'll need to start a bit early.

Rough budget per person (2 days, 1 night)

Homestay / garden resort — around 600–1,500 THB/night (split it if there are a few of you)
4 meals — around 600–900 THB, depending on how heavy you go on the seafood
Firefly boat — 60 THB/person (shared ticket) or 400–500 THB to charter a boat for your group
Khlong Khon mangrove boat — depends on the group package; ask the price when you book ahead
Fuel / minivan round trip — minivan is around 80–100 THB each way; if you drive, count fuel at actual cost

FAQ

When should I visit Don Hoi Lot to actually see the sandbar?

Go at low tide — the sand-and-mud bar is widely exposed for walking, and you'll see locals gathering razor clams. At high tide you'll just see open water. Check the tide times for the upper Gulf of Thailand before picking your day and time.

How much is the Amphawa firefly boat, and where do you board?

A shared ticket is around 60 THB per person, or about 400–500 THB to charter a whole boat for your group. You board at the municipal pier by the bridge over the canal in Amphawa Floating Market. The boats only run Friday–Sunday, set off at dusk, and take about 45 minutes to an hour.

Which season has the most fireflies?

Fireflies come out in numbers from the rainy season into early winter, roughly June to October. Moonless nights with no rain are when the blinking is clearest, while the peak dry season may have fewer — it's nature, so it can't be guaranteed.

Do I need to book ahead for Khlong Khon?

For group mangrove activities — the boat tour through the mangroves, mud-sledding, or replanting — you should contact the Khlong Khon community tourism group in advance so they can prepare the boats and gear. If you just want to stop for seafood at the edge of the mangroves, you can walk right in.

Can this nature trip be done in a single day?

Yes. If you only have one day, do Don Hoi Lot in the late morning, Khlong Khon in the afternoon, then finish with the firefly boat in the evening, skipping the coconut farm for now. Just leave Bangkok early so you can fit everything in.
