Central Botanical Garden (Phu Kae)

Central Botanical Garden (Phu Kae) is Thailand’s first officially registered botanical garden, opened in 1941 on Phahon Yothin Road in Saraburi, roughly halfway between Saraburi and Lopburi towns. Admission is free, open daily 08:00-18:00.

Experience

The garden is a lowland site set against a forested limestone hill — Phu Khae — rather than a cool highland retreat, and it’s managed by Thailand’s Royal Forest Department. The grounds span about 5,051 rai (roughly 8 square kilometres), combining planted collections with naturally regenerated dry evergreen forest. Paths and a one-way drive loop pass through themed sections: an arboretum, a palm collection, bamboo and medicinal-plant plots, and stands of native forest trees labelled for study. Birds and butterflies are common in the quieter corners, and there’s a small natural-history museum near the entrance.

Atmosphere & Timing

This is a place for a calm walk and plant-spotting rather than a manicured flower garden, and it sees few foreign visitors compared with Saraburi’s better-known temple sites like Wat Phra Phutthabat Ratchaworamahawihan. Weekday mornings are quietest; weekends draw more Thai families on the drive between Bangkok and the northeast.

Practical

The garden sits directly on Phahon Yothin Road (Highway 1), easiest reached by car, though Saraburi-Lopburi buses pass the entrance. Combine it with a stop at Muak Lek Arboretum if you’re touring Saraburi’s parks and gardens in one trip.

Insider Tip: Drive the one-way loop road rather than just walking the entrance area — the labelled forest-tree sections further in get almost no visitors even on weekends.

Watch out: There’s little shade along parts of the drive loop and forest trails. Bring water and insect repellent, and wear closed shoes — this is working forest, not a manicured park.
