Northeast of Phan Thiet the coastal road climbs over the slope of a Cham-Tower-topped hill and descends onto the long, sandy crescent of Mui Ne Bay. The formerly little-inhabited beach south of the fishing village of Mui Ne proper has seen some serious development in the last 15 years. Now it's a 15-km long strip of resorts that line up like pearls on Nguyen Dinh Chieu street, shaded by coconut palms. The main resort strip lies between the addresses of 2 and 90 Nguyen Dinh Chieu.
Given the choice, nature would move the sand around, much to the dismay of some developers. Beach sand tends to migrate southward, leaving some (but not all) spots above 90 Nguyen Dinh Chieu with just a concrete breakwater rather than sandy beach. Accommodations at higher addresses tend to be smaller and less expensive, somewhat removed from the main tourist section and more mixed in more with local life. If a sandy beach is important to you, some research is called for before booking in that area.
A few bargain hotels have popped up on the inland side of the road, across from the beach-side resorts. If you stay on the inland side, you will need to pass though one of the resorts to reach the beach, which might or might not result in some hassle from the guards. The resorts jealously guard their lounge chairs and palapas, though the beach itself is open to everyone. If all else fails, you can always access a nice sandy stretch of beach via the Wax Bar at 68 Nguyen Dinh Chieu.
