In the 1930s, Englishman Dr. Kerr started a small botanical garden in this location 12 kilometers along the Mae Sa Valley. The current garden was opened in 1992 and covers a large area that incorporates many vegetation types, including some rare species. It also houses research facilities, student accommodation and an information center. The mountain location makes it an enjoyable escape for everyone, particularly nature enthusiasts. The best time to see the flowers in bloom is during the cool season. Visitors can take a leisurely walk along the many winding nature trails and generally get away from it all.
