There are jain temple - lord shantinath and one digamber temple also, Dargah - Navgaja Pir and hindu temple - lord panchmukhi mahadev are also situated on the same hill. Also there are other goddess temples situated here. The well - veni vachhraj(situated opposite mahadev temple) is very much deep as said by local who look after the mahadev temple. The Mahadev temple is 3000 year old and similar to pashupatinath temple, Nepal.
Do not miss: Ruthi rani palace situated on small hill/ highest hill. You need to wear tracking shoes as only stone pathways leading you over there. Also the way to this hill is slippery so avoid in monsoon. Also avoid to visit Idar in summer season too.
Ghost Palace is ruined place and it is not much crowded with people. Jain temple is under renovation and dharamshala on hill is not in much use. But at the foothill near Rani lake the dharamshala is good for staying and food also.
