The pond occupies the site of a former sand quarry that ceased operations in the mid-20th century.
The emerald color of the water is a result of light refraction against the submerged sandy bottom and mineral content.
The pond serves as a natural reflecting pool for the 'Milenci' (Lovers) rock formation, one of the tallest in the reserve.
It is categorized as a protected area within the Broumovsko Protected Landscape Area.
Adršpašské pond, often referred to as Pískovna, is a flooded former sand quarry located at the main entrance to the Adršpach-Teplice Rocks nature reserve. The body of water is noted for its emerald-green color, caused by mineral content and depth. A circular walking trail surrounds the pond, providing a panoramic view of the surrounding sandstone rock formations. The site is a primary access point for the rock city circuit. It sits at an elevation of approximately 500 meters above sea level. Swimming in the pond is strictly prohibited to protect the local ecosystem and water quality.
The small wooden pier located on the northern shore provides a clear view of the reflection of the sandstone towers.
Walk the trail counter-clockwise to save the best vantage points for the end of your circuit.
Bring polarized sunglasses to better view the reflection of the sandstone towers on the water's surface.
Visit during the shoulder seasons to avoid the bottleneck of visitors at the narrow entry paths.
Do not attempt to swim in the water, as the banks are steep and the water temperature remains low even in summer.
The area is accessible year-round, though paths may be icy or muddy during winter and early spring.
Swimming, fishing, and watercraft use are strictly forbidden; stay on the designated gravel path.
