Which month of year is better to visit lingshan Buddha ?

I am Ashok Tapase, from Mumbai, India. I am Buddhist by faith and I am admirer of Emperor Ashoka. I have learned Ashokan Script on Ashokan Pillers in India and published a book on Ashokan Inscriptions in India.
I have visited all Ashokan Pillers in India and also all Ashokan Rock Inscriptions. I am very much interested in visiting Ling Shan Buddha.
Which month is better to visit Ling Shan Buddha so as there is less rush and pleasent atmosphere ? Is there any other means of reching top, for the people who cannot climb 216 steps ?
