Huay Mae Khamin Waterfall (Huay Mae Khamin Waterfall) is considered one of the most beautiful waterfalls in Thailand. Located within Srinakarin Dam National Park in Si Sawat District, Kanchanaburi Province, the waterfall originates from Huay Mae Khamin Stream, which flows down from the Kala Mountain Range before emptying into the Srinakarin Dam reservoir. The waterfall consists of seven tiers, each with its own distinctive character and poetic name: Man Khamin, Wang Na Pha, Chedi Rang, Chat Kaeo, Lai Chon Long, Dong Phu Suea, and Rom Kaeo.

One of the most remarkable features of this waterfall is that it is a limestone waterfall (Limestone Waterfall). The pale limestone surfaces remain relatively free from algae compared to many other waterfalls, allowing the water to flow softly in delicate strands resembling a curtain. This creates a unique and picturesque landscape unlike many other waterfalls in Thailand. The waterfall flows throughout the year, although water levels may decrease slightly during the dry season.

Each waterfall tier offers a different experience. Tier 1, "Man Khamin," is easily accessible and suitable for families. Tier 2, "Wang Na Pha," and Tier 3, "Chedi Rang," feature natural pools and shaded relaxation areas surrounded by forest. Tier 4, "Chat Kaeo," is the most famous and iconic section of the waterfall. Water cascades elegantly over large limestone terraces, creating a stunning curtain-like effect. When sunlight reflects through the mist, the scene becomes particularly spectacular and is highly popular for photography and sightseeing. Tiers 5, "Lai Chon Long," Tier 6, "Dong Phu Suea," and Tier 7, "Rom Kaeo," offer a quieter atmosphere and are ideal for nature lovers seeking a more immersive forest experience.

Within the waterfall area, visitors can enjoy a 2.2-kilometer nature study trail connecting all seven tiers. The national park has developed wooden walkways, bridges, and stairways throughout much of the route, making it convenient for visitors of all ages, including families with children and elderly travelers.

In addition to its scenic beauty, visitors can swim in designated areas approved by park authorities, particularly in the lower tiers where natural pools and gentle currents provide safe conditions. However, visitors should always follow park regulations and avoid swimming during periods of heavy rainfall or flash-flood warnings.

Another feature that makes Huay Mae Khamin highly popular is its cliffside camping ground near Tier 4. From here, visitors can enjoy panoramic views of the Srinakarin Dam reservoir, especially at sunrise when the sun emerges above the water and surrounding mountain ranges. The campground is often regarded as one of the most beautiful camping areas in western Thailand. Facilities include restrooms, shower rooms, restaurants, welfare shops, and visitor service areas, making it ideal for overnight stays in nature.

The surrounding ecosystem consists of mixed deciduous forest, dry evergreen forest, and natural bamboo forest, providing habitat for a variety of wildlife including squirrels, hornbills, insect-eating birds, and numerous butterfly species. In particular, Tier 6, "Dong Phu Suea" (Butterfly Forest), is well known for its abundance of butterflies during the rainy season and early winter.

The waterfall offers different experiences throughout the year. During the rainy season (June–October), water levels are at their highest and the forest becomes lush and vibrant. During the cool season (November–February), temperatures are pleasant, making it perfect for camping and sunrise viewing. During the hot season (March–May), water levels decrease somewhat, but the area remains beautiful and considerably less crowded.

Although both Huay Mae Khamin and Erawan Waterfall are famous limestone waterfalls in Kanchanaburi Province, Huay Mae Khamin offers a more peaceful atmosphere, fewer crowds, and camping grounds located closer to the waterfall itself. It is therefore an excellent destination for travelers seeking a genuine nature retreat.

Huay Mae Khamin Waterfall perfectly combines the beauty of a limestone waterfall, a rich natural ecosystem, nature study trails, swimming areas, quality camping facilities, and breathtaking views of the Srinakarin Dam reservoir. It remains one of the must-visit natural attractions in Kanchanaburi Province.

• From Kanchanaburi City, take Highway 3199 (Kanchanaburi–Si Sawat Road), passing the entrances to Erawan Waterfall and Srinakarin Dam. Continue along the paved Erawan–Huay Mae Khamin Road (Highway 4002). The total distance from Kanchanaburi City is approximately 110 kilometers. The road is fully paved and in good condition, allowing sedans, vans, and small buses to reach the waterfall entrance comfortably.

• The main parking area is located at Tier 4 (Chat Kaeo), the central point connecting all seven waterfall tiers.

• The most beautiful period to visit is August–December, when water levels are high, forests are lush, and the weather is refreshing.

• Wear suitable hiking shoes or non-slip footwear, as the trails between waterfall tiers involve walking up and down stairs and pathways.

• Visitors planning to camp overnight should reserve camping space in advance, especially during the cool season and long holiday periods.

• Pets are not allowed inside the national park, and food or beverages (except drinking water) are prohibited around the waterfall area to help preserve cleanliness and the natural ecosystem.
