Mahuli is a popular trek in Sahyadris on Mumbai-Nasik highway. It is advisable to carry snacks and mineral water along with you. The directions to the top are very clear in the form of white marking on rocks right through. You can also hire a boy from the village near the Temple to help you reach quickly.
Usually a dog from the temple will lead the way and so even if you don’t get a guide, the Dog will play that role!
