Hoa Lu and Trang An represent the perfect harmony between Vietnamese history and breathtaking nature. Hoa Lu, the ancient capital, stands as a testament to the country’s past, featuring majestic temples nestled against rugged mountains. Not far away lies Trang An, a UNESCO World Heritage site famous for its spectacular "eco-tourism" boat trips. As you glide along the crystal-clear water, you are surrounded by towering limestone cliffs and hidden water caves. This area is often called an "outdoor geological museum," offering a serene and mystical atmosphere that captures the heart of every traveler.
