The annual flower festival at Loei’s famous hilltop, Phu Ruea, ended earlier this month, but the blooming of the colorful winter flowers is ongoing until the end of February, thanks to its location 1,365 meters above sea level which makes the weather chilly all year round. Rumor has it that temperatures could plummet to lower than 10 degrees Celsius this season. More information at Phu Ruea National Park, 042-884-144.
