The tunnel is located near the Dr. Phol Klibua mine and can be accessed via the same route. It is not far from the scenic viewpoint at Heaven Hill. This tunnel allows vehicles to drive in, and upon entering, visitors will emerge from another tunnel that used to be a lead mining site. It has recently opened for tourists to explore. There are pickup trucks available, accompanied by a guide, to take visitors through the experience. The cost is 200 Thai Baht per person, with a capacity of about 8 people per vehicle. If your group has fewer than 8 people, you will need to book the entire vehicle for 1,500 Baht. Alternatively, if you're comfortable driving your own vehicle (a pickup truck), you can do so under the condition that an officer rides along to ensure safety and provide information about the mine. The cost for this option is 1,000 Baht per vehicle. Tours are available throughout the year. For inquiries, please contact the Cooperative Tourism Association.
