About 20 km south of Phan Rang is the small fishing village of Mui Dinh. It sits at the edge of large sand dunes and coastal hills. Sitting at the top of one of those hills is the Mui Dinh Lighthouse. It is s a 15 minute walk up a steep path, but well worth it because of the great views. It is also a great location for a picnic, so bring food and drinks. The sand dunes bordering the beach are also awesome to explore.
