Phu Kradung National Park
Located in the north eastern province of Loei , the park is one of Thailand's most romantic spots. The 1360 meters high mountain might have received its name Phu Kradung from its bell like shape ( kradung means bell in Thai ).
The park is largely covered with seasonal tropical rain forest and ever green forests. The 60 square kilometers (mountain top) plateau is a savanna of pines, oak, beech, etc.
Phu Rua National Park

Phra That Si Song Rak
Located on a hill by the Man River and built in 1560 on the border of the Ayutthaya and Lang Xang Kingdoms, Phra That Si Song Rak symbolizes the resolve of the kings of these two kingdoms not to invade each other territory and to join forces against Burmese invaders.
