Durdle door is part of the Jurassic Coast and is located in Dorset, England. After parking the car, I walked down the tourist track to reach Durdle door. Before I reached the pebbled beach to view the natural limestone arch, there is a platform in the middle of the cliff. This platform gives you a spectacular view of the sea. The sea is like a chameleon. Depending on her mood, the sea has shades of green or blue.
