After entering the temple, need to get down a few steps in the main room called Gabhara to have glimpse of the Lord Shiva. There is one Shivalinga at the centre of Gabhara.
The best thing I like about this temple is its never crowded, and not commercialized yet. People get enough time for darshan and get blessings from Bholenath.
Only at Maha Shivratri temple is overcrowded. There is Big Fair on Maha Shivratri. On this day more than 4-5 lakh people visit the temple to seek blessings from lord Shiva. Maha shivratri Fair continues for 3-4 days starting 2 days prior and extending to 1 day after shivratri as well. Temple is additionally crowded on all Mondays of Shravan, Month of Hindu Calendar. Definitely worth a visit and easily accessible by train from Mumbai. Visit this temple if you ever been to Ambarnath.
Getting There and Distance: How to reach Ambarnath
By road, its a one and half hour drive. Temple is located about 2 km from Ambarnath Railway Station (East). From Mumbai, It is better to go to Ambarnath (which is on the central line) by train and then take an auto-rickshaw (share rickshaws which go to Ulhasnagar @10 rupees).
