Why Choose Lan Ha Bay for Your Swimming Adventure?

While Halong Bay draws millions of tourists annually, Lan Ha Bay remains a hidden gem offering equally spectacular scenery but with fewer crowds and more pristine swimming conditions. Located southeast of Cat Ba Island, Lan Ha Bay features over 300 limestone karsts and islands, creating a secluded paradise for swimming enthusiasts.

What sets swimming apart:

  • Clearer Waters: The emerald waters of Lan Ha Bay are typically cleaner and more transparent than the more heavily trafficked areas of Halong Bay.
  • Secluded Beaches: Lan Ha Bay boasts numerous untouched white sand beaches tucked away between dramatic limestone formations.
  • Diverse Marine Life: The bay’s less disturbed ecosystem supports a richer variety of marine creatures to observe while swimming.
  • Calm Waters: Protected by surrounding islands, Lan Ha Bay offers tranquil swimming conditions with gentle currents throughout most of the year.
  • Authentic Experience: Fewer tourists mean a more intimate connection with the natural beauty of Vietnam’s coastal landscape.
