Phu Tub Berk

Introduction: The Peak of Cabbage Fields and Sea of Mist

Situated in Wang Ban Sub-district, Lom Kao District of Phetchabun Province in Lower Northern Thailand, Phu Tub Berk (also spelled Phu Thap Boek) is the highest peak in Phetchabun, standing dramatically at 1,768 meters (5,800 feet) above sea level. Inhabited primarily by Hmong hill-tribe communities, this towering mountain is famous across Thailand for two distinct features: its vast emerald-green cabbage fields covering rolling hillsides and its year-round cool climate with spectacular morning "Sea of Mist" (Thale Moch) formations.

Offering an alpine-like highland escape just a 5-hour drive north of Bangkok, Phu Tub Berk attracts road-trippers, campers, and nature photographers. Visitors come to stay in cliffside glamping domes, drive winding mountain switchbacks, and wake up to dense white clouds rolling across mountain valleys below.

Key Highlights & Highland Landmarks

Phu Tub Berk offers panoramic vistas, unique highland agriculture, and cool mountain weather:

1. The Highest Viewpoint & Trigonometric Benchmark Point

Located at the summit of the mountain near the meteorological station, this 1,768-meter viewpoint features an iconic thermometer tower structure and panoramic 360-degree views overlooking the winding Route 2331 switchbacks and surrounding mountain ranges.

2. Endless Hmong Cabbage Fields

Phu Tub Berk is Thailand's largest cabbage-growing center. Whole mountain ridges are carved into vibrant terraced agricultural fields cultivated by local Hmong farmers. The harvesting season (from July to December) paints the hillsides in lush shades of green.

3. Year-Round Sea of Mist & Cool Climate

Due to its high elevation, temperatures remain cool year-round (averaging 15°C–22°C during the day and dropping to 5°C–12°C at night). Following rain showers or during cool winter mornings, thick sea-of-mist clouds fill the valley below, creating an ocean-like cloudscape.

4. Wild Himalayan Cherry Blossoms (Thailand's Sakura)

During the cool months of December and January, thousands of wild pink cherry blossom trees bloom along the roadsides and inside nearby national park areas, turning mountain ridges pink.
