Namtok Phlio National Park

This section is being updated and will be available shortly.

Namtok Phlio National Park protects forested hills southeast of Chanthaburi town, centred on the famous Phlio Waterfall. One of Thailand's older national parks, it is best known for the crystal pool below the falls teeming with soro brook carp, and for two royal monuments built in memory of Queen Sunanta.

Few Thai waterfalls combine natural beauty and royal history like Phlio. The short, shady walk to the falls, the swarms of fish visible in clear water, and the nineteenth-century chedi and pyramid erected under King Rama V make it Chanthaburi's signature nature stop, easily reached from town.

The multi-tiered Phlio Waterfall and its fish-filled plunge pool are the stars, alongside the Alongkorn Chedi and the pyramid-shaped memorial to Queen Sunanta. A pleasant nature trail loops through evergreen forest, and the stream crossings and mossy boulders give the park its cool, green character.

Walk the paved trail to the falls, watch or wade among the carp where permitted, and visit the two royal monuments beside the stream. Longer nature trails explore the surrounding forest, and picnicking near the entrance area is popular with Thai families on weekends.

Do not miss the main waterfall viewpoint, the swarming soro brook carp in the lower pool, the Alongkorn Chedi and the stone pyramid containing memorials to Queen Sunanta. The stream-side path itself, crossing small bridges under tall forest, is as memorable as the destination.

Arrive at opening time on a weekday and you may have the falls nearly to yourself. Quieter upper vantage points above the main tier reward a short scramble, and the forest along the nature trail hides butterflies, birdlife and impressive strangler figs most visitors hurry past.

The royal monuments tie the park to King Rama V, who visited Phlio repeatedly and honoured Queen Sunanta here after her death. Thai visitors often treat the site with quiet reverence, and observing this blend of nature outing and remembrance is part of the experience.

The park protects moist evergreen forest on the Chanthaburi hills, home to macaques, butterflies, hornbill sightings and abundant stream life. The falls flow year-round, strongest late in the rainy season, and short marked trails make the forest accessible without serious trekking.

Children love feeding-frenzy views of the carp and paddling in designated shallow areas when conditions allow. Paths to the main falls are short and manageable with kids, and the picnic lawns near the entrance make it an easy family half-day from town.

There is no nightlife at the park; it operates as a daytime destination and the gates close in the late afternoon. Evening entertainment means returning to Chanthaburi town for riverside dinners, night markets and a quiet drink.

The classic shot pairs the waterfall with the chedi or pyramid in the foreground. Slow-shutter images of the cascades, the shimmering mass of carp in clear water, and light shafts through the forest canopy all reward a tripod; mornings give the softest light.

King Rama V visited Phlio many times in the late nineteenth century and ordered the Alongkorn Chedi built, later adding the pyramid memorial holding relics of Queen Sunanta, who drowned in 1880. The area was declared a national park in the 1970s, among the earlier entries in Thailand's park system.

For Chanthaburi people, Phlio is a beloved weekend escape and school-trip staple, and the memorials keep royal history alive in local memory. Vendors near the gate sell fruit and snacks from surrounding orchard communities, linking the park to the province's farming life.

November to February combines full, clear water with cool, dry weather. Late rainy season, around September and October, brings the most powerful flow but slippery paths. Weekday mornings avoid the weekend crowds that gather at the main pool.

Chanthaburi's hills catch heavy rain from roughly June to October, keeping the falls strong but trails muddy. March to May is hot though shaded, and November to February is pleasantly cool and dry, the most comfortable season for walking.

The park itself hosts no major festivals, but visits pair well with provincial events: the fruit festival season around May and June, Songkran in April, and Loy Krathong in November back in town. Important royal memorial days may bring commemorative activity at the monuments.

Spend the morning walking to the falls and monuments, then picnic or lunch near the entrance. In the afternoon, continue to Laem Sing's beaches and historic sites or return to Chanthaburi town for the waterfront and gem streets, keeping the whole outing to one relaxed day.

Two to three hours covers the falls, monuments and a short trail at an easy pace. Add time for swimming spots, picnics or the longer nature loop, and the park comfortably fills half a day.

The park entrance lies roughly fourteen kilometres southeast of Chanthaburi town off the Sukhumvit highway toward Trat. Songthaews and local transport run toward Phlio from town, though many visitors hire a car, motorbike or driver; from Bangkok, reach Chanthaburi by bus first, about four hours.

Inside the park, everything centres on walking: paved and dirt trails link the entrance, falls and monuments over short distances. Wear grippy footwear for wet stone, and expect to leave vehicles at the car park near the headquarters.

Chanthaburi bus terminal is the nearest long-distance hub, with connections along the eastern seaboard. Local songthaews serve the Phlio area from town, and the nearest airports, Trat and U-Tapao, are each an hour or more away by road.

The park opens daily during daylight hours, typically from morning until late afternoon, as with most Thai national parks. Exact times can vary seasonally, so check locally or with the Department of National Parks before a tight schedule.

Standard national park entry fees apply, with separate rates for Thai nationals and foreign visitors and small vehicle charges. Fees are collected at the gate in cash; check current rates locally as they are revised from time to time.

Simple restaurants and stalls cluster near the park entrance, selling noodles, som tam, grilled chicken and cold drinks, with fruit vendors in season. For fuller menus, Chanthaburi town and the Laem Sing coast offer seafood and Thai standards within an easy drive.

Chanthaburi treats worth seeking after your visit include sen chan noodles, crab dishes, durian and mangosteen in season, and fruit preserves from local orchards. Stalls near the falls often sell seasonal fruit picked nearby, a fitting snack for the drive.

Most visitors stay in Chanthaburi town, where guesthouses and mid-range hotels are plentiful, or at beach resorts around Laem Sing and Chao Lao. The park area itself has limited lodging; national park camping or bungalows may be available, so ask the headquarters if you wish to stay close.

Costs are modest: the park fee, cheap eats at the gate and local transport keep a visit inexpensive. Hiring a car or driver for the day raises the budget but adds flexibility for combining the falls with beaches and town sights. Carry cash in Thai Baht.

Stalls near the entrance sell snacks, seasonal fruit and simple souvenirs rather than serious shopping. Save gem browsing, dried fruit and durian chips for Chanthaburi town, where weekend markets provide far more choice.

Rocks around the falls are slippery, so mind your footing and supervise children near water. Do not feed or provoke macaques, secure food in bags, avoid swimming in strong wet-season flow, and follow ranger signs about where entering the water is allowed.

The main path toward the falls is relatively short and partly paved, but steps, roots and wet stone limit wheelchair access beyond the entrance area. Visitors with limited mobility can still enjoy the lower stream and monument surroundings with assistance.

Signage at the park includes English, and rangers manage basic English, though Thai dominates. A polite wai, and phrases like sawasdee and khop khun, smooth interactions; asking staff to point on a map works well when words fail.

Come early, wear shoes with grip, and bring a change of clothes if you plan to get wet. Keep a respectful manner at the royal monuments, do not bring food to the pool edge where fish and monkeys gather, and carry out everything you bring in.

Pack water, insect repellent, sun protection, swimwear with a modest cover-up, sturdy sandals or shoes, and a dry bag for electronics near the spray. Cash for entry fees and stalls is essential, and a small towel earns its keep.

Never feed the fish or wildlife, take all litter out, and stay on marked trails to protect the forest floor. Choosing refillable bottles and respecting no-swim zones helps rangers keep this long-protected park in good condition for the next visitor.

Laem Sing Beach, the Red Building and Khuk Khi Kai historic sites sit toward the coast nearby, with Oasis Sea World in the same district. Chanthaburi town's waterfront, cathedral and gem market are a short drive north, making a natural full-day circuit.

The park is managed by Thailand's Department of National Parks, Wildlife and Plant Conservation, with a headquarters and visitor centre at the entrance. Rangers there provide trail advice, current fees and safety notices; the TAT office covering Chanthaburi also supplies regional information.
