The ideal time to visit Thien Ha Cave is summer when sunlight shines brightly. Although hot weather will cause discomfort for tourists when visiting, this is an exception. Ninh Binh and Thien Ha Grotto are covered with green trees and calm rivers, and when it’s sunny, the lights shining into the cave make it seem bright.

Besides, visitors will feel the temperature difference inside and outside when they visit the cave in the summer. The temperature inside the cave will be 12 degrees Celsius lower than outside. That means even if it’s hot and sunny outside, you will feel much cooler when entering the cave. In winter, thanks to the natural insulation layer, the temperature inside will be much warmer than outside. So Thien Ha Cave is suitable for visiting both in summer and winter.

Besides, on beautiful sunny days, visitors will see places where light shines into the cave, creating a beautiful scene. If you’re lucky, you’ll see the “heaven’s gate” inside the cave, an opportunity to take a great photo.

Thien Ha Dry Cave is situated within a limestone mountain range that was formed during the Triassic period, approximately 250 million years ago. Although only about 200m long, the dry cave is located high up, where it receives a lot of light, so it’s easier for visitors to observe. Thanks to those lights, the cave becomes sparkling, and the stalactites seem to be plated with gold.
