Harihareshwar is a town in Raigad district, in Maharashtra, India. It is surrounded by four hills named Harihareshwar, Harshinachal, Bramhadri and Pushpadri. The river Savitri enters the Arabian Sea from the town of Harihareshwar. Towards the north of the town is the temple of Lord Harihareshwar, said to have been blessed by Lord Shiva. Hence Harihareshwar is often referred to as Dev-ghar or "house of God".
Besides a major pilgrimage center, Harihareshwar is a popular beach resort with two beaches, one to the north and the other to the south of the temple. Maharashtra Tourism Development Corporation has a resort on the south beach. Harihareshwar, along with Shrivardhan and Diveagar Beach forms a popular weekend beach destination from Pune (190 km) and Mumbai (210 km).
