Khao No-Khao Kaeo is a limestone mountain that has Wat Khao Lo at its foot. A stairway leads to the cave at the peak where a large Buddha image sits in front.

When King Rama V visited here via the Ping River, he stayed overnight on the mountain. The province later built a monument to commemorate the occasion. There are numerous monkeys at the foot of Khao No mountain and you can see plenty of bats that live in the cave flying out to feed in the evening, making a long black line in the night sky. Khao Kaeo nearby also has bats flying out at night
