Arriving in Co To Island, you will be immersed in a truly heaven with smooth white sandy beaches and pure sea water along with gentle wind. The most fascinating feature is the white sand on Co To Island, which is rarely seen in Northern Vietnam.  Some slices of the mountains that contain sa huynh (golden sand) create a special beautiful mountain color. The golden sand color under the sunshine, by the blue of the sea and the white of the waves, creates a spectacular and amazing scene.

III. What to Do in Co To Island?

1. Calm and Beautiful Beaches


There are 3 main beaches here in Co To Island which tourists visit the most: Tinh Yeu Beach, Hong Van Beach and Van Chai Beach. Among these, Van Chai seems to be the cleanest beach, while the other two sometimes get clogged with plastic. All beaches are often really calm, with clear blue sea and very smooth white sand stretches. Especially, the beautiful white sandy beaches here will immediately help you relax and unwind.  

While walking and watching the scenery around the sea, you will find the bungalows that look really creative, friendly and close to nature. If you want to enjoy the gentle and fresh sea breeze, you can book a room in that house. With just an open window, you will be able to watch the sunrise and sunset everyday. 

Standing in the vast sea and sky and enjoying the gentle, salty breeze, you will find yourself lost in this peaceful paradise. Here, you and your family or friends can participate in sports such as soccer, volleyball or simply cover yourself with sand,…. In addition, you can also bring camping gears to sleep overnight here – a great experience for your exciting summer.

To experience more of the nature, you can go kayaking or scuba diving to watch the lovely, colorful fish weaving in the “forest seaweed” winding with the waves. The most romantic time at this beach is in the evening, in which you can enjoy a seafood feast with fresh squid, shrimp, fish or nail snails in the sound of the waves and under the shimmer the spirit of the delicately arranged lanterns.


2. “Photoshoot” material Places

2.1. Co To Lighthouse


Going to the east side of the archipelago, you will find the Co To lighthouse. The lighthouse was builts in the late 19th century, and it is one of 30 “night sea eyes” operating throughout the territorial waters of Vietnam.  It is located on top of a mountain, 5 kilometers far from the town. The lighthouse is located at an altitude of 100m above sea level, and next to the main light, there is also a smaller light.

Currently, the lighthouse has been invested in solar lighting with automatic and semi-automatic control systems. Thanks to the lighthouse, the people who lit the sea lamp no longer have to row the boat to light the sea lamp with kerosene like in the old days. 

To get to the lighthouse, it is quite an adventure since the forest on the mountain is dense and tropical, therefore hiking would take time and some effort. However, it is a must visit when you come to Co To island thanks to the wonderful panoramic views of the whole island that it offers that sparks great imagination in our minds.

IV. What to Eat in Co To Island?

The price of nail-shaped shellfish in local market is about: VND 140.000 – 180.000/kilograms 

2. Jellyfish salad (Salad Sứa)

Following, they will mix it with other ingredients such as herbs, papaya, chicken, lemon, etc. to make its flavor sour and sweet. 

3. Grilled Oysters (Hàu Nướng)

A wide range of dishes can be made from oysters, however, grilled oyster is voted the best by locals and tourists. After being processed, oysters are mixed with a little oil, and then grilled. When the oyster turns yellow, the chef will add some scallions and peanuts to it. In some places, they also put cheese in the oyster to fit the appetizer of foreign tourists. It is important that you be careful to avoid overcooking, as it will harm the oyster’s flavor and texture.
