Horse Island is a small island in the Summer Isles archipelago off the northwest coast of Scotland. It is one of several rocky isles in the group and is not permanently inhabited.

Visitors encounter a largely natural coastline used by seabirds and marine wildlife rather than amenities or built attractions. The island is visited mainly for wildlife observation, photography and short landings from local boat operators.

Like many small Scottish islands, Horse Island has seen only occasional human use, historically for grazing or seasonal camps, and has no continuous modern settlement. Its landscape is dominated by rock, turf and coastal vegetation.

The Summer Isles lie off the coast of Ross and Cromarty near Achiltibuie and Ullapool in northwest Highland Scotland, and Horse Island sits within that group, accessible only by sea.

  • Access: There are no visitor facilities on the island, so landing requires a private boat and visitors must be self-sufficient and aware of tidal and weather conditions.
