Siriphum Waterfall possesses a deep historical background and holds immense spiritual significance for the Thai people. Originally, this waterfall was known locally as Lao Pue Waterfall, named after the headman of the Hmong village in the Khun Klang area. Later, when The Royal Agricultural Station Inthanon was established to improve the quality of life for highland ethnic groups, M.C. Bhisadej Rajani, then Chairman of the Royal Project Foundation, requested a new name from His Majesty King Bhumibol Adulyadej the Great for auspiciousness. The name Siribhumi was graciously bestowed, derived from the combination of the names of the Royal couple Siri from Her Majesty Queen Sirikit the Queen Mother and Phumi from His Majesty King Bhumibol Adulyadej.

The dendrological and ecological interest of Siribhumi Waterfall lies in its status as a national conservation area for ancient flora. The area surrounding the waterfall was developed into Siriphum Royal Garden, which serves as a collection hub for temperate ornamental plants, particularly the "Fern Garden" that gathers numerous rare fern species from both Thailand and abroad. It also features various species of Rhododendrons that bloom brilliantly during the winter. The cascading water does not only offer scenic beauty but also functions as a natural Mist System, maintaining humidity for epiphytic plants and groundcover throughout the year.

The topography of Siribhumi Waterfall is unique, characterized as a Twin Waterfall flowing down a steep granite cliff, clearly visible from a distance in the Khun Klang village area. The two streams plunge in long white lines, contrasting sharply with the deep green of one of the most fertile hill evergreen forests on Doi Inthanon. Geologically, the cliff face is part of a natural uplifted fault line, creating a high gradient that makes the falling water resemble white curtains swaying in the wind. This creates an enchanting allure for photographers and naturalists seeking to capture the perfect balance between the strength of the rock and the grace of the water.

Beyond its beauty, this waterfall is a model for highland water resource management under the care of the Royal Project Foundation. Water from Siribhumi is systematically managed for use in temperate vegetable research greenhouses and for community consumption. This reflects the concept of wise reliance on nature and the preservation of watershed forests for sustainable water use. Entering the waterfall via a short nature study trail allows visitors to experience the essence of an ancient hill evergreen forest that is strictly conserved.

Visiting Siribhumi Waterfall is more than just viewing one of the tallest waterfalls in the Royal Project; it is about touching a historical milestone in Thailand's highland development. The tranquility and the chilling mist circulating around will lead visitors to truly understand the phrase The Forest is Life. It is a landmark that provides both agricultural academic knowledge and the profound joy found in this supreme auspicious beauty.

• Private Car: From Chiang Mai city, take Highway 108 to Chom Thong, then turn right onto Highway 1009 up Doi Inthanon. At KM 31 (National Park Headquarters), turn right toward The Royal Agricultural Station Inthanon. The waterfall is located behind the station.

• Public Transport: Take a yellow songthaew (Chiang Mai–Chom Thong), then transfer to an Inthanon-bound songthaew. Get off at the front of Khun Klang village (KM 31) and walk or hire a local transport service to the waterfall.

• Additional Info: Vehicles can easily access the parking area in front of Siribhumi Garden. The entrance is slightly steep but is a well-paved asphalt road.

• Best Visiting Season: December to February offers the coldest weather and the most beautiful garden flowers, ideal for wide-angle shots showing the parallel twin falls.

• Walking Path: The path to view the waterfall consists of concrete steps and soil paths. It is short but watch for slipperiness caused by moss near the falls.

• Photography: The best vantage point is from the main road in Khun Klang village to see the falls across the cliff, and another is within Siribhumi Garden to see the base amidst giant ferns.

• Safety: Do not climb the waterfall cliffs as they are very steep and slippery. Wear warm clothing as the temperature under the forest canopy near the water is lower than usual.

• Support: Visitors are encouraged to support Royal Project products and the restaurant at the station to contribute to the income of the local highland farmers.
