Rach Vem Beach, or in Vietnamese Bãi Rạch Vẹm, belongs to the commune of Ganh Dau.
This rural beach on Phu Quoc Island is in a beautiful setting, but similar to Rach Tram Beach, Rach Vem is a working fishing village and not really a place for beachbumming. The village however is picturesque and the people are really friendly and you might find some remote beaches if you follow the coastline.
Nearby there is the Phong Lan guesthouse, but the rest of the area is fairly undeveloped, so bring water and food if you want to spend time on the remote beaches near Rach Vem village, where the life has not changed much during the last years.
Many houses are built on stilts, especially the shelters out on the water. The area is something like a parking lot for fishing boats, while the sea is dotted with traps for various types of sea creatures. That makes a nice spot for taking pictures.
The inhabitants are of Khmer ethnicity and their daily life includes breeding chickens and ducks that run around between the huts, together with stray dogs. Expect the children to follow you around, because tourists are quite rare in this area.
As everywhere on Phu Quoc Island, if you are able to speak Vietnamese or Khmer, you can have a nice chat with the locals. But don’t bring up the war between Vietnam and Cambodia and the terror regime of the Khmer Rouge. It is still a highly sensitive topic.
