Nestled in the lush forest of Prachantakham District, Prachinburi Province, lies a small and quietly hidden waterfall in Ban Khao Noi, Bu Fai Subdistrict. This is Sompoi Waterfall. Though not a large or nationally famous cascade like those in major national parks, it carries a unique charm that wins over many visitors. Clear water steps down across rock shelves for roughly 400 meters, forming a string of small pools that are safe and pleasant to dip in.

 

The essence of Sompoi Waterfall is friendly simplicity. Nature remains pristine and peaceful, without crowds—ideal for those seeking rest. The sound of the falls is gentle rather than roaring, like a soft natural melody flowing over rocky riffles along the stream. The varied drops create several spots for wading and relaxing, making it suitable for families, groups of friends, or anyone wanting to be close to the forest without long hikes or steep climbs.

 

The stream corridor is lined with mature trees and small plants clinging to crevices and banks. Mist from the falls keeps the forest green year-round, so visitors feel refreshed from the first steps into the area. Rest spots range from broad rock slabs ideal for sitting and watching the water, to shaded areas perfect for spreading a mat, reading, or enjoying a simple picnic—always with good trail manners: keep voices low and pack out all trash.

 

As for the name Sompoi Waterfall, a common local explanation links it to the “sompoi” shrub, a native plant used in traditional rites to symbolically wash away misfortune. The belief adds a cultural layer to the place—as if wading in the stream releases fatigue from daily life. While there is no definitive written proof, the tale reflects the bond between local communities and the surrounding nature.

 

To reach Sompoi Waterfall from downtown Prachinburi, follow the same route used for Than Thip Waterfall, heading toward Bu Fai Subdistrict. Drive along the rural road (Ror.Por.Chor.) until about the 14 km marker, then turn off and continue roughly 2 km to the falls. The route is mostly paved with some concrete sections. In the rainy season, drive carefully as surfaces may be slick with standing water. Using online maps helps confirm turns and parking spots.

 

The waterfall forms a sequence of low steps along the stream. Water flows over naturally polished rock, giving the stone a smooth sheen. Shallow pools appear at intervals. During the rains, the flow is stronger and more dramatic—beautiful, but requiring extra caution. In late-rain to early-cool season, the water remains clear and cool, ideal for photos and easy walking. In the hot season, the flow can diminish in places, yet the quiet, shaded atmosphere remains the key draw.

 

Popular activities include wading in shallow pools, strolling along the stream to discover fresh photo angles, and resting beneath large shade trees. If visiting with children, supervise closely—stream rocks can be slippery. Wear footwear with good grip, quick-dry clothing, and carry a bag for packing out your own trash. Responsible travel keeps areas like this pristine for the long run.

 

Compared with nearby falls such as Than Thip and Takhro, all three share the character of tiered, low cascades. But Sompoi Waterfall stands out for its tranquility and friendly, intimate setting. It suits visitors who want a light, unhurried nature fix. Plan a half-day or full-day loop: relax at Sompoi first, then continue to Than Thip or Takhro for a change of scene.

 

One key safety note: during off-season rain bursts or prolonged heavy showers, flash floods can arise unexpectedly. If you notice water turning muddy quickly or the level rising abnormally, exit the stream immediately and move to higher ground. Follow local advisories and avoid entering the water at dusk when visibility drops.

 

For smoother planning, pack essentials like non-slip footwear, a towel, change of clothes, sunglasses, sunscreen, basic first-aid, and a dry bag for phones or cameras. If picnicking, bring your own food and drinks—but keep the area clean and never leave leftovers that could attract animals to the wading spots.

 

The best time to visit is from late rainy season into early cool season when the water is ample and clear and the air is pleasantly cool. Still, safety first: when the flow is strong, choose to relax on rock slabs or shaded banks instead of entering deeper spots. In the hot season, although the flow may be lower, exposed rock strata and riffles photograph beautifully, especially in late-afternoon light.

 

Without a private car, access can be challenging since no public bus stops at the entrance. Feasible options include chartering a vehicle from Prachantakham District or hiring a local motorcycle taxi—agree on the fare and pick-up points in advance. Expect a short walk from the drop-off to the stream corridor.

 

Though Sompoi Waterfall is modest in scale, it holds real value in natural and local cultural terms. Respecting the site preserves it: no campfires, no loud music, and no soaps or shampoos in the stream. Remember we are guests—such mindfulness keeps the water clear and the place friendly to all forms of life.

 

For day-trip planning, an early start works well. Stop first at Sompoi Waterfall for 2–3 hours of relaxing, then connect to nearby Than Thip or Takhro Waterfalls. Later, head into town for local food, or visit cultural landmarks like Wat Kaew Phichit or the Prachinburi National Museum for a nature-and-culture day in one.
