In order to reach Cramond Island there is a walkway which is accessible during low tide. The walkway is 1 mile (1.6km) out to sea and is connected at low tide to Dunn Sands. There are concrete pylons on one side of the path which were put in place as an anti-boat boom during WWI.
The views from the top of the hill on the island over the Dunn Sands and walkway are stunning. People standing on the sands looked like they were walking on water.
