Black Holm, Tidal island in Orkney Islands, Scotland.
Black Holm is a tidal island west of Corn Holm in the Orkney Islands featuring distinctive red sandstone rock formations. These formations emerge from the water at low tide, creating a prominent geological feature in this part of the archipelago.
This formation is part of the ancient Orkney archipelago, where maritime communities have navigated these waters since prehistoric times. The red sandstone geology shaped how people adapted to living along these particular coasts.
Local fishermen have long recognized this formation as a landmark in their daily work on these waters. The island remains embedded in how Orkney residents understand their maritime surroundings.
Access requires careful planning around tide schedules, as water levels determine when you can safely reach the island. Check local tide conditions before visiting to ensure you can view the formations properly.
At low tide this formation connects to Corn Holm through Isle Rough, creating a temporary natural pathway between the islands. Walking across this temporary connection reveals additional sandstone details that remain hidden underwater at other times.
