2. Top Things to Do in Cat Ba in August

While August in Cat Ba comes with occasional rain, it’s also a rewarding time to explore its lush landscapes and quiet bays. Many outdoor activities remain accessible during dry hours, and the scenery is particularly vivid thanks to recent rainfall. Here are the top things to do:

2.1. Trek Through Cat Ba National Park

One of the highlights of the island, Cat Ba National Park is lush and alive in August. The forest trails are shaded and cooler, especially in the morning. The trek to Ngu Lam Peak offers panoramic views of the jungle and limestone mountains, especially atmospheric when mist rolls in after a light rain.

Guided hikes are recommended for those unfamiliar with tropical terrain. Be sure to bring proper footwear and water.

2.2. Go Kayaking or Take a Boat Tour in Lan Ha Bay

Lan Ha Bay, often called the quieter sibling of Ha Long Bay, is stunning in August. You can rent a kayak or join a boat tour to explore hidden lagoons, floating fishing villages, and remote beaches.

Morning tours offer the calmest weather and the clearest skies. If you're lucky, you might catch sight of golden-headed langurs, one of the world’s rarest primates native to the region.

2.3. Visit Hospital Cave

On rainy days, Hospital Cave is an ideal indoor attraction. This historical site was used as a secret hospital and shelter during the Vietnam War. Inside, visitors can explore the multi-level chambers carved into limestone, complete with operating rooms and sleeping quarters. The cave is cool and dry, perfect for escaping the afternoon heat or sudden downpours.

2.4. Relax on Cat Co Beaches

Cat Co 1, Cat Co 2, and Cat Co 3 are the main beaches near Cat Ba town. In August, they’re less crowded than in peak season and still offer soft sands and swimmable waters.
Choose the early morning or after 4 PM to avoid heat and possible rain. Some beachfront cafes and bars provide shaded spots to relax with a drink and enjoy the breeze.

2.5. Take a Sunset Cruise

Despite the weather, many evenings in August offer beautiful sunsets across Lan Ha Bay or from Cannon Fort. Booking a sunset cruise is a relaxing way to enjoy the coastal scenery, especially with fewer boats out at this time of year. Some cruises include light snacks and cocktails on board.

2.6. Explore Cai Beo Floating Village

Believed to be one of the oldest floating villages in Vietnam, Cai Beo is still home to hundreds of local fishermen and their families. Take a guided boat tour through the village to see traditional floating homes and experience a quieter, authentic side of island life.
