The landscape cluster of Hon Yen in the central coastal province of Phu Yen was recognised as a national relic site in April 2018. This is an ideal destination for seeing coral reefs.
Located 30km from Tuy Hoa city, Hon Yen island is well-known as a favourite check-in destination among young travellers.
Aside from being home to popular tourist attractions such as Da Dia reef and Bai Xep beach, Hon Yen island attracts a large number of visitors thanks to its beautiful coral reefs on land and crystal-clear blue water.
When the tides recede on the island, visitors are able to savour the scenic views of coral reefs on the land.
According to local residents, the tide only recedes in the afternoon of the first few days of the month or during the middle of the lunar month and lasts only for a few days. If visitors miss this then they have to wait another 15 days to have the chance of glimpsing the coral reefs again.
