LIGHT: Safe and beautiful hiking experience in the dark along the UNESCO World Heritage Site The lighting concept focuses on two main principles: fascinating natural surroundings and safe hiking experience. The natural properties such as water and green are illuminated with a neutral color temperature, which emphasizes the freshness and organic quality. The trail itself is illuminated in warm and inviting color temperature, with a focus on even lighting, good overview and safety. The contrast between the two color temperatures creates a drama that you can only experience in natural surroundings.
