Two kilometres past the Maesa Elephant camp is the Queen Sirikit Botanic Gardens , featuring a shorn mountainside displaying 227 hectares of various exotic and local flora for conservation and research purposes. Near the administration building is the orchid collection, containing over 400 species, the country's largest public display. The highlight of the garden is the glasshouse complex sitting near the mountain peak.
The Rainforest House recreates a southern Thai forest with ferns, palms, ginger and other tropical species.
