Co To Island is a fresh destination for visitors on Vietnam’s northern seaboard. Renowned for its untouched beaches and peaceful atmosphere, the island is gaining popularity with tourists as a natural and peaceful destination, free from the hustle and bustle of over-visited tourist spots. Located in Quang Ninh Province, it’s an alternative choice to Ha Long Bay, but every bit as beautiful. Before organizing your trip, it’s worth knowing about the climate, travel, and essential places to visit that make Co To Island an interesting destination for your holiday.
Is Co To Island Worth Visiting?
Co To Island is a serene, lesser-known paradise off Vietnam’s northeast coast, belonging to a 40–50-island archipelago in Quang Ninh Province. Celebrated for its unspoiled white sandy beaches, crystal-clear waters, and lush forests, this island stands apart from busier coastal destinations.
Travelers usually praise its peaceful ambiance and genuine charm. TripAdvisor travelers label it the “green pearl” that everyone wants when craving a tranquil escape. Attractions are wide-open beaches like Hong Van and Van Chay, sea-cliff scenery at Cau My rock, and camping out under the stars.
There is also an array of activities that make the island worth visiting. Beach-hopping, kayaking, jet-skiing, and snorkeling are thrilling activities, while hiking to Co To Lighthouse gives stunning views. Actual cultural experiences like squid fishing at night with the locals, enjoying freshly-caught seafood during a beachside barbecue, or staying in homestays add character and depth to your vacation.
Planning advice: Despite being in its earliest stages, the island has good facilities – accommodations, transport rentals, restaurants, and a single ATM. Some of the facilities close down in the off-season, however, so it’s best to pre-book for months of high season. For people seeking a mix of nature, genuine culture, and relaxation away from crowds, Co To Island Vietnam is well worth visiting.
