Although development started in this area, it's still worth a visit. The best place, by far, is Hoa's Guesthouse. He is even recommended by Lonely-Planet but with wrong adress for 2 year already. So here is how you can find him: 1) Take a motorbike-taxi in Hoi An to bring you to Marble Mountains. Fix the fare!!! 50.ooo Dong is the regular price.
2) At Marble Mountain draw a line between the big pagoda (you can't miss it) and the beach. If you see a police-school you have arrived at your destination
3) If you see big bunkers for airplanes from the American War turn around and go back :)

De Hoi An, 30 minutes de motorbike et vous etes a china beach. Grande plage, tres agreable avec pleins de restaurant de fruits de mer frais. (de la mer a ton assiette). c est la que les Americains on debarques pour les guerre de destruction. Et en continuant sur la route vers le nord, on apercois un immense Boudha sur la colline Nui Son tra. Il vaut le detour, la vue sur la baie est magnifique.

Take a Moto from the City to this beautiful sandy beach, which is always empty.
