Sunflower Field at Bueng Sam Phan

The sunflower fields at Bueng Sam Phan are seasonal farmland in the hills of Tambon Sa Kaeo, Phetchabun — not a permanent attraction, and not the same place as the Bueng Sam Phan reservoir roughly 25 km away that shares the district’s name. Sunflowers bloom here in a short window from December into January, peaking in early-to-mid December most years. Outside that window, the same slopes are bare ground or growing other crops — there’s nothing to see here most of the year.

When they’re in bloom, the flowers climb the hillsides around Phu Chuk in bands rather than lying flat, so the view is as much about the rolling terrain as the flowers themselves — hills rising and falling behind rows of yellow blooms against open sky. The district runs an annual festival around the bloom, typically in early December, with a largest-sunflower contest and local agricultural stalls alongside the viewing.

Watch out: This is working farmland owned by individual growers, not a managed park. There’s no confirmed fixed entrance fee — access and parking arrangements are set locally and can vary by season or by which farmer’s field you’re visiting.

Outside the festival period, the atmosphere is rural and unhurried — locals working the land rather than a tourism operation built around the view. That changes for the couple of weeks each December when the bloom peaks and visitor numbers pick up alongside the festival.

Insider Tip: Confirm the bloom is actually up before making the trip — sunflower planting dates shift year to year, and arriving even two or three weeks early or late can mean bare fields instead of the display you came for. Check recent local reports or the district office (0 5681 0801) closer to your travel date.

The fields sit in Bueng Sam Phan district, reached via Highway 21 through Nong Phai district and then Highway 225 toward the Chaiyaphum direction. Bring sun protection and comfortable shoes for walking the farm tracks; there’s no shade once you’re among the flowers. If you’re passing through the district, Bueng Sam Phan reservoir is a separate stop worth combining with the sunflower fields when both are accessible, though they’re not within casual walking distance of each other.
