Co To island is undergoing a strong transformation with the focus on promoting and developing underwater tourism services and products for tourists. Not only meeting the increasing demand for experiences of tourists, this direction also helps standardize and enhance the brand, creating a difference for Co To on the map of sea and island tourism.

In recent years, Co To island has become a familiar destination thanks to its wild beauty, fine white sand beaches, many beautiful small islands and cool climate. However, this potential has not been fully exploited; some services and experiential tours have been illegally exploited, creating a bad impression...

Meanwhile, the demand for exploration experiences, especially underwater tourism services and products, tends to increase rapidly. According to statistics, in July 2025, Co To welcomed more than 129,000 visitors. Underwater tourism services and products are a special highlight for young tourists. Because now, tourists coming to Co To not only swim, take photos, but also experience jet skiing, parasailing, visit islands, dive to see corals... "From that demand, underwater tourism products are identified as the spearhead to elevate and differentiate Co To, while increasing the attraction, competitiveness and length of stay of tourists" - Deputy Head of Co To Culture, Tourism and Science and Technology Department said.

Accordingly, in 2025, Co To special zone has deployed a pilot project for underwater entertainment and island sightseeing activities, opening up opportunities to exploit a variety of products such as jet skiing, parasailing, kayaking, and sup. The selected locations include Van Chay, Hong Van, Vung Tron, Ba Chau, and Co To Con. At the same time, the district focuses on managing and exploiting island tours such as the 3-island tours (small Co To island, Ca Chep island, and Su Tu island) and the journey to Tran island, creating a chain of linked sea-island products.

Co To also constantly improves the quality of services at Hong Van and Van Chay beaches, while regulating spontaneous beaches such as Tinh Yeu beach. The highlight is that coral diving products and kayaking, sup, and sunset canoeing are developed in a controlled manner, ensuring safety, limiting spontaneous activities, and maintaining the image of a civilized destination.

Co To Special Zone has implemented a pilot project for inter-island tours, requiring businesses to meet legal, vehicle, rescue personnel and environmental standards. At the same time, it is testing the Net Zero tour model, associated with the “Plastic Waste Free District” project, creating a chain of experiences that reduce emissions from transportation, accommodation to entertainment - very suitable for environmentally sensitive underwater products.

To promote its potential and position its brand, Co To has identified underwater tourism and island tours as its core products. The orientation focuses on four solutions: Diversifying products (sea sports, island tours, night economy), investing in infrastructure (renovating Co To passenger port, completing wharf/port infrastructure, controlling temporary wharfs in Bac Van - Hong Van), tightening management (handling spontaneously, controlling prices, safety, environment) and developing human resources (rescue training, training diving instructors, international standard sea sports).

It is known that in the long term, Quang Ninh province aims to build a marine reserve associated with Tran island to sustainably manage resources and develop controlled eco-tourism. With synchronous steps, Co To is aiming to become a green, safe, and experience-rich sea-island tourism center.

Upgrading underwater tourism products is not only a temporary solution to increase the number of visitors, but also a long-term strategy to affirm Co To's position on the island tourism map. From strict management, infrastructure investment, environmental attention to human resource training, all are aimed at the common goal: Building Co To into a unique and distinctive destination.
