Laem Son National Park

This section is being updated and will be available shortly.

Laem Son National Park protects a long ribbon of Andaman coastline south of Ranong town, taking in casuarina-backed beaches, mangrove channels and a scatter of offshore islands including the Kam group. Its centrepiece on the mainland is Hat Bang Ben, a vast, flat beach near the park headquarters, and the whole park remains one of the quietest marine parks in southern Thailand.

Laem Son offers national-park nature without national-park crowds: empty beaches, boat trips to unspoiled islands and mangroves alive with birds and macaques. For travellers working down the Andaman coast, it is the easiest way to see what Thai shorelines looked like before mass tourism.

Hat Bang Ben's enormous low-tide sands and casuarina shade, boat excursions to Koh Kam Yai, Koh Kam Nui and Koh Khang Khao, and mangrove creeks threading behind the shoreline are the park's stars. Sunset views across island silhouettes and the chance of spotting hornbills, sea eagles and crab-eating macaques round out the highlights.

Swim and stroll at Bang Ben, arrange longtail or speedboat trips to the islands for snorkelling and beachcombing, and explore mangrove channels by kayak where boats and paddles can be hired. Camping under the casuarinas, birdwatching at dawn and long picnics are the park's other classic pastimes.

Hat Bang Ben and the view from its sands across the offshore islands is the essential experience, followed by a boat day to the Kam islands for clearer water and coral. The mangrove forests behind the beach reward even a short paddle or walk along their fringes.

Quieter beaches north and south of the headquarters area, reachable by short walks or local boats, see almost nobody midweek. The park's estuarine corners shelter kingfishers and mudskippers, and staying overnight in park accommodation or a tent delivers star fields and dawn beaches that day-trippers never see.

Small fishing communities live along the park's edges, and watching longtails work the channels or buying seafood near the park approach connects you to coastal Ranong life. Moken sea-people heritage threads through this coast; treat villages respectfully and ask before photographing people or homes.

The park spans beach, casuarina woodland, mangrove and sea, so wildlife ranges from macaques and monitor lizards to shorebirds, hornbills and wintering waders on the flats. Offshore, the islands hold patches of coral and clear seasonal water, while the mangroves function as nurseries teeming with juvenile marine life.

Families enjoy Bang Ben's shallow, gently shelving sands, which give children huge safe areas to run and paddle at low tide. Camping, macaque-spotting and easy boat trips make the park a good adventure for school-age kids, though facilities are simple and shade beyond the treeline is limited.

Nightlife consists of campfire-free quiet, sea sounds and exceptional stars, with park rules keeping evenings subdued. Ranong town, about an hour away, is the nearest place with evening restaurants; most park visitors simply eat early and sleep early.

Sunset from Hat Bang Ben, with offshore islands stacked on the horizon, is the signature frame. Low-tide reflections, casuarina silhouettes, mangrove textures and the white curves of the Kam island beaches all photograph superbly, and morning light favours the mangrove side.

The park was established in the early 1980s to protect this stretch of coast and its islands from development and overfishing, taking its name from a cape within its boundaries. It has since become an important refuge as neighbouring coastlines developed, while remaining one of the least-visited marine parks in the region.

The surrounding districts live from fishing, rubber and oil palm, and park-edge communities supply boats and seafood to visitors. Southern Thai courtesy, Muslim and Buddhist households side by side, and a relaxed attitude to time set the tone; simple politeness and modest dress fit in everywhere.

November to April is the season, with calm seas for island boat trips and dry days for camping. The park stays open in the May to October monsoon, but island crossings often stop, seas turn rough and the beach shows its wilder face.

Expect heavy, persistent rain from roughly May to October, courtesy of Ranong's exceptionally wet monsoon, then a dry, breezy stretch from November to February and rising heat in March and April. Sea conditions track the seasons closely, calm in the dry months and boisterous in the wet.

The park itself hosts no festivals, but nearby communities mark Songkran in April and Loy Krathong in November, and southern temple and mosque fairs punctuate the year. Long Thai holiday weekends bring domestic campers, the closest the park gets to a busy season.

With one day, reach Bang Ben by mid-morning, walk the beach, picnic under the casuarinas and stay for sunset. With two, camp or use park lodging, then dedicate the second day to a boat trip around Koh Kam Yai, Koh Kam Nui and Koh Khang Khao with snorkelling stops.

A half day suffices for Bang Ben alone, a full day if you add a boat trip, and an overnight stay unlocks the park's quietest hours. Most visitors slot Laem Son in as one or two days within a Ranong itinerary.

The park entrance road leaves Highway 4 south of Ranong town, roughly an hour's drive away, then runs several kilometres west to the coast at Bang Ben. Private car or motorbike is easiest; buses along Highway 4 can drop you at the junction, leaving a motorbike-taxi ride for the final stretch.

On the mainland section you walk the beach and short trails, while everything offshore moves by chartered longtail or speedboat arranged near headquarters. A motorbike is handy for exploring beaches beyond the core area; distances inside the park are modest.

Highway 4 buses between Ranong and points south pass the park turn-off, and Ranong town holds the nearest bus terminal and airport. From the junction, local motorbike taxis or pre-arranged transfers cover the last leg to the shore.

The mainland park area is typically accessible during daylight hours, with overnight stays possible for campers and guests of park accommodation. Boat trips run to daylight and tide schedules; check at headquarters on arrival for current arrangements.

As a national park, Laem Son charges an entry fee, with the usual higher rate for foreign visitors and small charges for camping or park lodging; boat charters are priced separately by distance and group size. Bring cash and confirm current rates at the gate.

A simple park-area restaurant and vendors operate near headquarters in season, and small southern Thai eateries line the approach road and highway junction. Choices are basic, so campers often bring supplies from Ranong town or the nearest market town.

Southern coastal cooking rules here: grilled fish, sour yellow curries, squid and shell-fish from the very channels you look at. Roadside stalls add sticky rice, fried chicken and fruit, ideal for assembling a beach picnic.

Options include park bungalows and a casuarina-shaded campground at Bang Ben, plus a handful of low-key resorts and guesthouses along the coast road outside the boundary. Ranong town, an hour away, offers the full range of budget to mid-range hotels for those preferring a day trip.

Costs stay low: park entry, modest lodging or camping fees and cheap southern food. The main discretionary spend is an island boat charter, which is most economical shared among a group; overall the park is a bargain compared with famous marine parks further south.

Beyond drinks, snacks and a few park souvenirs near headquarters, there is little to buy inside Laem Son. Stock up in Ranong town or highway market towns, where dried seafood and local cashews make good take-homes.

Swim with care outside the calm season, as currents and surf strengthen when the monsoon builds, and keep food secured from bold macaques. Sandflies bother some visitors at dawn and dusk, so repellent helps, and boat trips should be postponed without argument in rough weather.

The headquarters and the top of Bang Ben beach are reached by vehicle on flat ground, making the shoreline viewable for visitors with limited mobility, though soft sand and simple facilities limit further movement. Island trips involve boarding longtails from the beach and are difficult without assistance.

Park staff and boat operators speak Thai first, with basic English at headquarters in season. Learning a few Thai courtesies, writing down numbers when negotiating charters and using translation apps for anything complicated keeps everything friendly and clear.

Come with cash, sun protection and your own snorkel gear if picky about fit, and aim for a falling tide at Bang Ben when the sands are at their widest. Weekdays outside Thai holidays are gloriously empty; book park lodging ahead for weekends.

Carry water, sunscreen, insect and sandfly repellent, a hat, swimwear, dry bags for boat trips and cash for fees and charters. Campers need full kit plus food; a torch, power bank and light rain layer are wise in any season.

Follow park rules strictly: no coral touching or collecting, no feeding macaques, all litter packed out and reef-safe sunscreen only. Choose local boatmen, keep drone use within regulations, and remember the mangroves are nurseries, so paddle quietly and take nothing.

The Kam islands and Koh Khang Khao lie within the park's own waters, while Koh Phayam and Koh Chang are reached from Pak Nam Ranong to the north. Ranong town's hot springs, Ngao Waterfall and the Khao Fa Chi viewpoint fill out a rounded provincial itinerary.

Laem Son is managed by Thailand's Department of National Parks, Wildlife and Plant Conservation, with a staffed headquarters near Hat Bang Ben handling fees, lodging and boat information. The regional Tourism Authority of Thailand office covering Ranong can advise on seasonal conditions before you travel.
