Shree Ghanteshwar Hanuman Mandir is most spiritual and believed temple for Hindu community. The accessibility is very simple, we visited there last month with our family with the bus. you can take a local bus from Mumbai to Khar for temple and bus will drop you next to the mandir. the temple is very beautiful with thousands of bells handing in the temple with a very beautiful statue of Lord Hanuman. You can also visit local parks and hotels if you are in Khar. You get hotels at an average price not too high nor too low and there is 100% security of your luggage no worries of that.
