How to visit Lenyadri Caves and Bhimashankar Jyotirling ?

Hey Punians, I reside in Mumbai and Planning to explore Maharashtra on solo trip. I am planning a trip to Lenyadri Caves and Bhimashanker Jyotirlingam. What is the best way to commute to these sites from Pune itself ? Onlune search was not of much help since i don't have my own ride. Thanks.
