THE ROCKS: Cramond Island is a lump of tough dolerite, part of a series of igneous intrusions formed across this area around 330 million years ago. It has been beautifully exposed and shaped by flowing ice during the ice age. On the shore, various sedimentary layers are exposed, giving a glimpse into the geological variety of this area.

THE WALK: We will walk across the causeway at low tide, circle around the island and return. Distance 4.5km. This is classified as an Easy Walk, although the causeway can be slippery in places. It may be wet, windy or cold. Come equipped with strong footwear and waterproof clothing.

MEETING POINT & ROUTE: Start of the causeway to Cramond Island. Grid reference: NT190771 | Nearest Postcode: EH4 6NU | What3Words: sank.coins.fairly | Route Map.
