Khao No is a prominent limestone mountain in Banphot Phisai District, holding historical significance as King Rama V stayed at Wat Khao No during his royal visit along the Ping River. Today, it is a popular adventure destination featuring a steel stairway with over 700 steps leading to a 360-degree panoramic viewpoint of rice fields and limestone formations. The base of the mountain is home to a large colony of monkeys and a cave housing a significant reclining Buddha image.
