Queen Sirikit Botanic Garden >> Ministry of Natural Resources and Environment

There are 4 main garden trails, and a Greenhouse Complex for visitors to enjoy various kinds of plants, both native and exotic species.

Arboretum Trail: Along the trail, visitors will see plants (mostly trees) grouped according to their botanical families. More than 10 families of plants are featured, such as banana (Musaceae), palm (Arecacea),

pine (Pinaceae), pea (Caesalpiniaceae), ginger (Zingiberaceae), cycad (Cycadaceae); and ferns and their allies.

Climber Trail: A collection of vines or climbers (weak-stemmed plants which scramble upward by attaching themselves to other plants or objects). A beautiful trail with more than 200 species of climbers.

The Waterfall and Ornamental Beds: Passing by the Mae Sa stream and Mae Sa Noi Waterfall, the path leads to the ornamental beds and eventually onto the Thai Orchid Collection. Plants from the families Agavaceae, Moraceae, Verbenaceae, Euphorbiaceae, Cactaceae,

and Clusiaceae are featured along the trail.

Medicinal Plants: The garden values the importance of indigenous knowledge in plants and their medicinal properties. One of the garden trails is designated specifically for the medicinal plants. In this collection, many native species with medicinal value are displayed along the trail.
