Just east of Ha Long Bay is Bai Tu Long Bay. Both of these places share many of the same geological characteristics, the exception being that Bai Tu Long is a bit of a hidden gem and has a lot fewer tourists. This is what makes Bai Tu Long such an interesting alternative to northeastern Vietnam's most popular destination. With limestone karst islands just as impressive as those in Ha Long Bay, Bai Tu Long doesn't have as many grottos but is equally beautiful.

The Cathédrale Saint-Pierre is a Roman Catholic cathedral also listed as a national monument by the French government. It houses an organ that was built between 1840 and 1842 by Nicolas-Antoine Lété, an organ builder of the French king. A lot of concerts are organised there, especially in summer.

For brave souls seeking the world’s most exhilarating swim, Devil’s Pool delivers an unforgettable adrenaline rush. This natural rock pool, sculpted by millennia of erosion, sits precisely on the precipice of Victoria Falls, where the Zambezi’s waters cascade 100 metres into the gorge below. Accessible only during the dry season (typically mid-August to mid-January), the experience begins with a boat ride to Livingstone Island — the very spot where explorer David Livingstone first laid eyes on the falls in 1855. The adventure continues as visitors wade and swim through gentle currents, guided by experts to the pool’s edge. Here, a submerged rock lip creates a natural barrier, allowing swimmers to peer safely over the thunderous drop while the river’s force swirls around them. In the driest months (October-November), some may walk across exposed rocks to reach the pool, though a guide remains mandatory. While the sight of bathers lounging at the waterfall’s brink makes for iconic photos, the reality is even more breathtaking. As over 500 million litres of water plunge past each minute, the pool’s deceptive calm contrasts with the roaring abyss just beyond your fingertips. Five daily tours depart for this once-in-a-lifetime experience, though nature dictates the schedule — high waters from March to May render the pool inaccessible. For those who dare, Devil’s Pool offers not just a swim, but a visceral connection to the raw power of Africa’s greatest waterfall.
