The beach is situated within the Cat Ba Biosphere Reserve, designated by UNESCO.
The water depth increases rapidly a few meters from the shore, unlike the shallower beaches found on the mainland.
The cliff-side walkway connecting the three Cat Co beaches was carved directly into the mountain rock to provide pedestrian access between the coves.
The beach faces the East Sea and is prone to strong waves during the typhoon season (late summer months).
Cat Co 1 Beach is the largest of the three primary sandy coves on Cat Ba Island in Hai Phong, Vietnam. It is characterized by its semicircular shape, enclosed by forested limestone mountains on three sides. The beach is connected to Cat Co 2 and Cat Co 3 beaches via a concrete cliff-side walkway known as the Cat Ba coastal path. The water is deep and suitable for swimming, though currents can become strong during high tide. The beach features a backdrop of dramatic karst formations typical of the Lan Ha Bay region. It remains the most commercially developed of the Cat Co beaches, offering numerous facilities for visitors. It serves as a primary access point for water activities like kayaking and boat excursions to nearby islets.
From the elevated cliff-side walking path overlooking the bay to capture the entire crescent shape of the beach.
Walk the coastal path during low tide to safely access the neighboring beaches.
Wear water shoes, as the seabed features rocky patches common in karst-formed coastal areas.
Visit on a weekday to avoid the peak crowds of domestic tourists arriving from Hai Phong and Hanoi.
Avoid swimming outside of marked buoy areas due to unpredictable currents and sharp limestone rocks under the surface.
The beach is prone to seasonal closures during severe weather warnings or typhoon events between July and September.
Standard beachwear is acceptable, but cover-ups are encouraged when walking through the town area.
