Lalu is a new natural attraction of Sakaeo. It is located in BanKlong Yang of Tambon Tapraj. It is approximately 36 km. Away from the town hall. “Lalu” is a Khmer word meaning “pierced”, due to the natural phenomenon of spectacular rock formations caused by a shallow depression in the ground where soil erosion has produced strange shapes like city wall, cliff, rocket and others also found in “Phae Muang Phi” of Phrae Province. For this reason, Lalu is also known as “New Phae Muang Phi”.
