The noise arrives before everything else. A dull rumble, then a splash getting closer, then the cold of the air laden with water vapor hitting your face as you ascend the path in the forest. The Erawan Waterfall, in the Si Sawat district of Kanchanaburi province, does not announce itself with tourist signs but with the sound of its own power. Seven levels of waterfalls follow one another along the course of the Khwae Yai River, each with its own natural pool, each with a different character, from accessible to wild.
The Erawan National Park was established in 1975 and covers about 550 square kilometers of dense tropical forest. The name Erawan comes from the three-headed elephant of Hindu mythology, a sacred figure in Thai tradition: according to legend, the shape of the waterfall at the seventh level resembles the head of this creature. It is not a legend hard to believe when standing in front of that white curtain of water that splits into three branches before plunging into the pool below.
The color of the water you won't forget
The detail that strikes every visitor, even those who have seen many tropical waterfalls, is the color of the water. It is not green, it is not blue: it is a saturated turquoise, almost unreal, produced by the high content of dissolved calcium carbonate in the river. The sunlight filtering through the treetops changes the shade every hour of the day, shifting from an emerald green in the early morning to a cobalt blue in the afternoon. In the lower pools, where the bottom is made of light sand and polished limestone, the effect is that of a natural pool illuminated from within.
Diving into these pools is allowed and encouraged at the lower levels. The water is cool even in the hottest seasons, and the current is manageable near the shores. But the detail that truly surprises visitors are the fish: Tor tambroides, a large local species, swim freely in the pools and approach bathers without fear, gently nibbling at the skin to feed on dead cells. It is not an organized service; it is simply the natural behavior of animals accustomed to human presence in a protected environment.
The path: seven levels, seven different experiences
The trail connecting the seven levels is about 1.5 kilometers long in total, but it requires attention because it alternates flat sections with climbs on slippery rock. The first three levels are easily reachable on foot in less than twenty minutes from the entrance and are the most frequented, with large pools and stable bottoms. From the fourth level onwards, the trail becomes more challenging: there are fixed ropes anchored to the rock to overcome some vertical sections, and the roots of the trees become improvised steps.
The seventh level is the one that justifies the entire climb. It is reached after about an hour of walking, and the difference compared to the lower levels is striking: fewer people, more silence, a higher waterfall cascading into a deeper pool surrounded by untouched vegetation. The water vapor rising from the waterfall creates a permanent mist that spectacularly filters the light during the central hours of the day. Here, the fish are even more numerous and less shy.
When to go and how to organize the visit
The park is open every day from 8:00 AM to 4:30 PM, with an entrance ticket of 300 baht for foreigners (about 8 euros) and 20 baht for Thai citizens. The best time to visit is between November and April, during the dry season: the water level is stable, the trails are safer, and the turquoise color of the pools is at its maximum saturation. During the rainy season, from June to October, the river flow increases significantly and some levels may be closed for safety.
To reach the park from Kanchanaburi, the nearest city, you can take a minibus from the local bus station: the journey takes about one and a half hours and covers about 65 kilometers. Alternatively, many visitors rent a scooter or join organized tours from the city. The most useful advice is to arrive at opening time, at 8:00 AM, to reach the upper levels before the heat becomes intense and before the lower levels fill up with visitors. Wearing trekking shoes with non-slip soles is essential: sandals are not suitable for the steeper sections of the trail.
The sound of the forest around the waterfalls
What photographs cannot convey is the sound dimension of the place. Each level has its own acoustics: in the flat stretches between one waterfall and another, you can hear the forest birds, the song of the cicadas, the rustling of the trees. Then, as you approach the next waterfall, the sound of the water grows until it covers everything else, and the steam rising creates a visual barrier that makes each level a separate world. It is this alternation of silence and power, of opening and closing, that makes Erawan an experience hard to compare with any other waterfall in the region.
