Is there any ksrtc rajahamsa bus fecility from mantralayam to dharmasthala?

As of my limited knowledge up to April 2023, there is no direct Rajahamsa bus available from Mantralayam to Dharmasthala operated by Karnataka State Road Transport Corporation (KSRTC). However, there may be other bus services available operated by private bus operators. To get the most up-to-date information on available bus services, I recommend that you check with KSRTC's official website or contact their customer service department directly.
