Cannon Fort is not only a work of historical significance, but also an impressive tourist destination with pristine, majestic, and very poetic scenes in Cat Ba island. For one of the best views in Halong Bay, visit Cannon Fort where you can gaze in awe at the panoramic vistas of Cat Ba Island – its forest-clad hills rolling down to the colorful cluster of fishing boats in the port and out to the emerald waters of the bay.
Cannon Fort was constructed by Japanese troops during World War II. Visitors get to explore underground tunnels, bunkers, trenches, two gun emplacements (one featuring life-size Viet Minh mannequins), and two viewing decks overlooking the island. It’s quite a treat because the historical remains are well-preserved. There’s even a cafe and a small museum. A short visit here will give you impressions of Vietnam’s turbulent past as well as the beauty that nature has endowed to this unique place.0
