Phu Kradueng National Park

Introduction: The Legendary Bell-Shaped Plateau

Situated in Si Bun Rueang and Phu Kradueng Districts of Loei Province in Northeastern Thailand (Isan), Phu Kradueng National Park is one of Thailand's most legendary, celebrated, and physically rewarding trekking destinations. Established in 1962 as Thailand's second official national park, this massive sandstone mountain features a famous flat-topped, bell-shaped plateau rising abruptly to 1,316 meters (4,318 feet) above sea level.

Covering 348 square kilometers, Phu Kradueng is renowned across Thailand as a rite of passage for adventurers, students, and hikers. The summit plateau spans over 60 square kilometers of high-altitude pine savannas, evergreen cloud forests, cascading waterfalls, wild rhododendron groves, and dramatic sandstone cliffs overlooking sea-of-mist mountain valleys.

Key Geographic Features & Iconic Viewpoints

Phu Kradueng's summit plateau offers a vast, flat playground connecting iconic natural landmarks along well-marked walking trails:

1. Pha Mak Ruk & Pha Lom Sak Sunset Cliffs

Located on the western edge of the summit plateau. **Pha Lom Sak** is the undisputed symbol of Phu Kradueng—a dramatic flat sandstone ledge extending out over a vertical cliff face with a solitary, bowing pine tree. It is world-famous as Thailand's ultimate mountain sunset spot, where hundreds of hikers gather every evening to watch the sun dip below mountain ridges.

2. Pha Nok Aen Sunrise Cliff

Located on the eastern cliff edge, just a short flat walk from the central park campsite. Hikers gather here in the early morning darkness to watch golden sunrise beams pierce through rolling white seas of fog filling the valleys below.

3. Summit Waterfalls & Red Maple Trails

The interior plateau features a network of peaceful forest streams and waterfalls, including **Pen Bob Waterfall**, **Tham Yai Waterfall**, and **Wang Kwang Waterfall**. During the cool season (December to January), red maple leaves fall across mossy stone stream beds, creating one of Thailand's rare autumn-like landscapes.

4. Anusawari Rock & Anodat Lake

A serene natural freshwater lake surrounded by pine forests and wild grasslands in the center of the plateau, serving as a peaceful resting spot during long day hikes.
