It's a shame how Halong Bay has been mercilessly spoiled by mass tourism. BUT, for visitors to Vietnam, there's still hope. Escape the crowds and polluted waters by sailing through Bai Tu Long Bay instead of the popular tourist route.
Halong Bay vs. Bai Tu Long Bay. What's the difference? Bai Tu Long Bay in Vietnam is part of the UNESCO World Heritage site that is much less populated with tourists and other boats than Halong Bay. Only certain companies have licenses for Bai Tu Long Bay, giving you a glimpse into this natural, karst-filled wonderland.
