25. The Scottish Highlands, Scotland/UK
The Scottish Highlands are famed for their remote, wild landscapes and dramatic beauty. Yet, this rugged region is also one of the most challenging environments in the UK to survive in. Unpredictable weather, sudden storms, freezing winds, and boggy terrain can catch even experienced hikers off guard. Navigation is tricky, and shelter is often scarce in the vast open moors and steep mountains. Unprepared visitors may quickly find themselves in real danger.
